As knowledgeable users of the Internet in 2024, we would do well to assume that nothing is 100% “safe” (I.e. there’s no such thing as perfect security/privacy).

However, some things, like Tor, can make your use of the Internet safer.

If all you’re doing is arguing that Tor shouldn’t be used because it isn’t/was never “safe”, then you might as well not use the Internet at all.

Agreed – you can never truly be completely "safe", but Tor remains the most privacy-preserving tool we've got.

When people say they're distrustful of Tor (for various reasons) to the extent they refuse to use it, they seldom suggest alternative tools/measures that provide anywhere near the level of safety offered by Tor.

They have the opposite of a point. The logical conclusion of that line of reasoning is that everyone should use privacy tools so no one can be singled out. And that ordinary users with "nothing to hide" should be the first to start using them.

I mean, sure. And while we're at it pigs should fly.

Functional security means understanding your risks, and using privacy tools is a risk - in the sense that it does single you out in the current environment.

Your actual communications can be secure, but that doesn't stop a bad actor/government from picking you up and beating you with a wrench until you talk - if they get suspicious enough.

Just saying "everyone should use these tools!" is not actually a counter-argument. It's a fine long term goal, but it's not addressing the real risk that some folks might be in.

Pigs have significantly higher density than birds and lack wings. Getting them to fly under their own power would be quite a challenge. By contrast, installing Tor Browser is actually pretty easy.

In general this is not what happens in e.g. the United States. The act of installing or using Tor doesn't in and of itself cause anyone to beat you with a wrench. Try it. Visit HN using Tor Browser. No one comes in the night to put a bag over your head.

> Just saying "everyone should use these tools!" is not actually a counter-argument. It's a fine long term goal, but it's not addressing the real risk that some folks might be in.

If you live in an authoritarian country and actively oppose the government, you are already doing something that will get you punished if you're caught and then the question is, which is more likely to get you caught? Tor has several measures to reduce the probability that you're detected. Private entry guards, pluggable transports, etc. You might still get caught, but these things reduce the probability, whereas if you openly oppose the government without using any privacy technology, you're much easier to catch. Using it in this case is pretty clearly to your advantage.

If you live in a country that has a modicum of respect for fundamental rights like privacy and due process, then you can use Tor when you're not breaking any laws and are just trying to avoid being tracked across the internet by Google and Facebook, because using Tor isn't in itself illegal. And doing this not only benefits you, it benefits the people in the first group who need it even more than you do, because it makes them stand out less.

So who are the people who shouldn't be using it?

There are no "100% safe" solutions. There will always be weaknesses and vulnerabilities in any system. The sort of criminal who requires or expects 100% safety is quickly going to be caught due to being a dullard.

As opposed to... people who undergo illegal activities with the intention to BE caught???

mtlmtlmtlmtl 5 hours ago | root | parent | prev | next |

As someone who's actually used Tor for illegal activities(buying drugs) this is completely missing the point. Criminals generally are not thinking about doing something completely risk free. The dumb ones don't consider risk at all, because they're desperate/addicted, and just hope/assume they won't get caught. More clever ones assume they'll be caught and try to make conviction less likely.

For instance, for buying drugs, the ordering isn't the risky bit. Receiving it in the mail is. Even if tor was magically "100% safe" the crime overall wouldn't be. The point of using tor is not to eliminate all risk, it's just to decouple payment from reception. I had my drugs intercepted by customs once, but they couldn't prove I ordered them, so they dropped the case. I'm sure it might've been possible for them to prove it if they spent a lot of resources trying to trace crypto transfers and so on, but police only do that if the fish is big enough because they're resource constrained.

Tor is just another tool criminals can use to reduce risk. It's not perfect, but for most things it's the best thing available.

The only 100% safe method is to not do the illegal activity at all. There's always a risk/rewards analysis to be performed when committing any act that could have negative consequences whether you're playing the stock market or doing credit card fraud. For any major criminal that gets caught, you can usually read the arrest affidavit which offers a pretty interesting look into how the criminal was caught despite the careful measures they took. The one for DPR is interesting to read and shows how despite taking careful measures, DPR left a trail of breadcrumbs that investigators used to track him down. His use of Tor was pretty solid (assuming the whole affidavit isn't complete parallel construction fiction) but it was everything else he did outside of it that got him in the end. There's another story of a university student that sent threats to his school to get out of an exam or something through anonymous emails over Tor. They only caught him because he was the only person using Tor on the school network at the time the email was sent. If he was off campus, he may have remained anonymous.

An analog crime I think about is the murders in Moscow, Idaho. The criminal did take some careful measures like wearing gloves but he left a knife sheath behind that contained DNA evidence. Everything else they had on him was circumstantial, he owned a similar car to what police thought they saw on people's doorbell cameras and his phone went offline during the time of the murders and also pinged a tower close to the crime scene hours afterwards. Police found a partial genealogy match to his DNA which I'm sure they compared to similar car owners and cell tower records. If he hadn't left the sheath behind, wore something like a Tyvek suit, and simply left his phone at home, the suspect pool would have likely been too large. His careful measures (turning off his phone, making multiple passes in his car) likely contributed to police focusing on him once the DNA proved a link.

AnthonyMouse 2 hours ago | root | parent |

Nope. Not even that is 100% safe because you can be falsely convicted of a crime you never even committed. Many privacy tools reduce that risk as well, because you're less likely to be convicted by e.g. a lazy prosecutor willing to take things out of context if you provide them with less source material to trawl through.

Here is what I don't understand: Let's say I as a private individual fund 1000 tor nodes (guard and exit nodes included) and have them all log everything. This could cost less than $5000 for a month, with some time needed to get guard node status.

I want to find a certain kind of person so I look for people that access a specific hidden service or clearnet url.

Surely eventually I'm going to get a hit where all three nodes in the circuit are my nodes that are logging everything? It will take a long time, and I can't target a specific person, but eventually I can find someone who has all three bounces through tor nodes I control, no?

bragr 21 hours ago | root | parent | next |

>This could cost less than $5000 for a month

I ran a bunch of nodes for a couple years and that's optimistic by perhaps an order of magnitude. No $5 a month VPS provides enough bandwidth to sustain the monthly traffic of a Tor node, and nodes need to be continuously online and serving traffic for about 2-3 months[1] before they will be promoted to guard relays. Throttling traffic to stay in your bandwidth allocation will just get you marked as a slow node and limit the number of connections you get. Sustaining just 1 Mbps will blow your monthly transfer allocation on the cheap tiers of both Digital Ocean or Linode.

[1] https://blog.torproject.org/lifecycle-of-a-new-relay/

belorn 20 hours ago | root | parent | next |

Now to add additional problems. 1000 tor nodes on a single platform would be very noticeable and geographically limited. Platforms also have different weight attached to them in the consensus, which adds further time requirements before a node is promoted. The developers do not want a single platform provider to be able to observe a large portion of all the traffic, so there are counter measures.

The attacker could try to create a handful of accounts on hundreds of platforms in as many countries as possible, assuming one verify that the platforms accepts tor and do not share underlying providers and data centers. The cost would then be the average price of said providers, which is going to be a fair bit more than the cheapest providers out there. Managing and spreading them out is also going to cost a lot of man hours. Also the secops need to be fairly on the point and need to be maintained quite strictly across all the providers.

Pardon my ignorance, but I thought it fruitful to ask: Are there any issues that can arise by doing this on a VPS?

I ask because I know of stories of law enforcement sending inquiries to owners of, say, exit nodes requiring certain information about given traffic. I don't know if this happens for middle-nodes (or whatever they're called).

Moreover, are there any issues with associating a node to, you know, your name and billing information?

I don't know much about this, and although I could look it up, I think that my questions - and your respective answers or those of others - might do some public service of information sharing here.

I never operated a TOR node, but as far as I know and heard from other sources, TOR realays don't get much attention from law enforcement, it any attention at all. Which makes sense: all they're doing is getting encrypted traffic in and giving encrypted traffic out. It would hard for them to link a relay node to a specific connection, and even if they do, you can't help them in any way: even you as the node operator are only able to see encrypted traffic.

Edit: there's a youtuber called "Mental Outlaw" that published a while ago some videos about setting up and operating TOR nodes. He sometimes gives inaccurate information regarding more theoretical topics, so I don't follow him much. But I think he can be trusted for this practical topics.

At the time Elizabeth Holmes was on trial and a lot my videos involved me reading ArsTechnica articles on the subject (credited) while offering my personal opinions on the matter. While not successful, those videos got more views than anything else I ever created. Was that a crappy thing to do? I didn't think so at the time and I don't think so now.

Plagiarism, generally.

Those are generally where my current model of plagiarism comes from.

A specific concern would be the inaccurate telling of information that isn't understood. A video saying, "Here I will summarize this HN thread," is perfectly ok, and a good thing. A video saying, "Here I will tell you how $thing works," should be well researched and cited. Doesn't matter if the content's entirely from an HN thread for from 40 different SEO farms, it's low-quality content and it's wasting everyone's time at best, and probably actively misinforming people. (Because how true and complete is information gleaned from HN comments anyway?)

Either they are grossly negligent/incompetent (IMO unlikely given the extent of their research), or they knew it was intercepted on purpose (either by law enforcement, the provider itself or one of their upstreams) and intentionally aren't saying so.

Before 2020 when /r/privacy stimulated conversation that was worthy of good discussion you learned Tor the software made less available nodes accessible with newer deployments, that’s why it got faster. Regardless of how many nodes existed. The routing shifted. Now it’s way faster and there's specifically designated guard nodes seemingly pinged repeatedly out to the same allied nations.

chatmasta 20 hours ago | root | parent | prev | next |

You don’t technically need separate nodes, just separate IP addresses. Although Tor has some marginal protections against circuits sharing relays with similar IP, so you couldn’t just get a /24 and hope they all get the same circuit.

tga_d 18 hours ago | root | parent | next |

Not only would you need the node to expose IPs with a wide enough distribution to allow the right path selection, you'd also need to have enough bandwidth available to look like distinct hosts, and ensure any losses in connectivity aren't correlated enough to draw attention (people monitor metrics.torproject.org pretty diligently, and would notice if there was a chunk of bandwidth coming and going in lockstep). At that point, the difference in cost to just actually running legitimately separate hosts is negligible. All empirical evidence points towards the status quo that has existed for most all of Tor's existence: if you want to identify Tor users, there are cheaper ways to do it than dominating the network (and those ways are expensive enough to be outside most people's threat models).

That said, any bandwidth anyone wants to contribute to mitigate such attacks is always appreciated, even if it's more useful for performance reasons in practice. ;)

The word "eventually" is doing a lot of heavy lifting here. Let's say you actually manage to add 1000 servers to the tor network somehow without getting detected. The network currently sits at just under 8000 nodes. For simplicity, lets also ignore that there are different types of nodes and geographical considerations and instead just ask what is the probability that someone randomly chooses three nodes that you own. The answer is less than 0.14%. If that someone decided to use 4 nodes to be extra-safe, that number goes down to 0.015%. And it decreases exponentially for every additional relay he adds. Combine this with the fact that tor nodes are actively monitored and regularly vetted for malicious behaviour[1], and these attacks become increasingly difficult. Could someone like the NSA with limitless resources do it? Quite probably, sure. But could you or any other random guy do it? Almost certainly not.

Edit: For all the cynics and doomsayers here, consider this: Tor has been around for a long time, but there has never been an uptick in arrests that could be correlated to cracking the core anonymity service. If you look closely at the actual high profile cases where people got busted despite using tor, these people always made other mistakes that led authorities to them.

75% [0] of all Tor nodes are hosted within 14 Eyes [1] countries, so it would actually be quite trivial for the NSA to de-anonymize a Tor user.

It baffles me that Tor Browser doesn't provide an easy way to blacklist relays in those countries.

Maybe someone, somewhere, has decided that allowing petty criminals to get away with their crimes is worth maintaining the illusion that Tor is truly private.

It's also worth noting that it's significantly easier to find the mistakes someone has made that could lead to their identity if you already know their identity.

This is what I believe. If they do have a way to track people, it wouldn't be worth blowing their cover for small stuff that wasn't a ridiculously huge national security threat that they could afford to throw away 20+ years of work for.

In fact there have been court cases that were thrown out because the government refused to reveal how their information was obtained... I think that usually means they're hiding it on purpose for a bigger cause. I also wouldn't be surprised if multiple SSL CAs are secretly compromised for the same reason.

keepamovin 11 hours ago | root | parent | prev | next |

The original purpose of TOR was to provide agents and handlers with a means of secure communication, allowing them to organize subversive or espionage activities. It was created by the Department of Defense to propagate their interests and spread democracy around the world using these secure capabilities. Given this context, it's not unreasonable to assume that TOR is still being used in a similar manner today.

Because of its origins, access to the identities of users on the TOR network—even if they could be de-anonymized—would likely be extremely restricted, compartmentalized, and classified. This would make it much more difficult for such information to be used in law enforcement proceedings. Perhaps that, rather than a technical limitation, is the reason most high-profile arrests related to TOR involve criminals making some other mistake, rather than the security of the network itself being compromised.

Additionally, it’s interesting to speculate that some of the secure private defense and intelligence networks—parallel or classified world internets—could themselves be implemented as possibly enhanced forms of TOR. It would make sense that nation-states, through shell companies and other disguises, might run and control many seemingly innocuous machines acting as secure relays in these parallel networks. While I have no data to back this up, it seems logical, given that TOR was originally created by the DoD and then open-sourced.

Why wouldn’t they keep something that works, build on it, and enhance it as a means to secure their own global communications?

I have no doubt that the government doesn't want to demonstrate how weak Tor is to the public, but it's also got to be dead simple to find those kinds of "other mistakes" they can use when they've identified the person they're looking for and can monitor whatever they do.

keepamovin 4 hours ago | root | parent |

What you’re claiming is not necessarily correct, but it’s an avenue of interesting speculation. Nevertheless, let’s clarify a few of your possible misunderstandings or points of confusion:

I’m not saying TOR is weak, nor that the reason for its concealment is to project a false sense of government strength.

What I am saying—and what you seem to have misunderstood—is that the TOR network is most likely used, precisely because of its strength, for highly sensitive clandestine operations. This results in blanket classification of all involved identities, making them inaccessible to law enforcement. Law enforcement likely understands this, which is why they don’t pursue it—knowing it’s a dead end. Instead, they rely on side-channel effects or mistakes made by criminals.

To my mind, this explains the public information we see.

Now that I’ve clarified, what do you think?

sangnoir 2 hours ago | root | parent |

> What I am saying—and what you seem to have misunderstood—is that the TOR network is most likely used, precisely because of its strength, for highly sensitive clandestine operations.

Tor seems to be a poster child of the "Nobody But Us"[1] principle the NSA likes so much: it's strong when used by American spooks, but weak when used against them. If a country developed body armor that's impervious to all rounds except their own special alloy rounds, their use and promotion of that armor is not evidence of its utter robustness.

I don't doubt a lot of darknet busts involve a lot of parallel construction - the intelligence community doesn't have to give detailed logs; summaries are enough (IP addresses, dates and times). This is before considering that the FBI is involved in both (counter) intelligence and law environment.

If you can find TOR nodes, so can the Chinese government. They can then just block these addresses.

Furthermore, the great firewall is quite advanced, they use machine learning techniques to detect patterns, so even if it is TLS on port 443, they may be able to detect it after they have gathered enough traffic. There are workarounds of course, but it is not as simple as just using a TLS tunnel.

godelski 17 hours ago | root | parent | prev | next | 

  > the US Navy
Tor was made for spies. But you know what's really bad for spies? If accessing a certain IP/protocol/behavior reliably reveal your spy status.

For Tor to be effective for hiding spies it has to be used by the public. Even if it's only nefarious actors (say spies + drug dealers + terrorists) it adds noise that the adversary needs to sort through.

What I fucking hate about many of these conspiracies is how silly it is once you ever work with or for any government entities. You can't get two police agencies in neighboring cities to communicate with one another. The bureaucrats are fucking slow as shit and egotistical as fuck.

It's important to remember that the government and even a single agency (like the NSA) is just as chaotic, disconnected, and full of competing entities as any big tech company has (if not worse). Yeah, most of the NSA is focused offense, but there's groups working on defense. Those groups are 100% at odds. This is true for the 18 intelligence agencies. They have different objectives and many times they are at odds with one another and you bet each one wants to be getting credit for anything.

The US involvement should warrant suspicion and with any technology like Tor you should always be paranoid. But it's not proof. Because guess what, the US wants people in other countries to use high levels of encryption to hide from their authoritarian governments while the US can promote democracy movements and help put a friendly leader into a position of power. AT THE SAME TIME they also want to spy on their own people (and there are plenty of people in the gov that don't want this). Inconsistency is the default because it's a bunch of different people with different objectives. So the US gov both wants Tor to be secure and broken at the same time.

>> I can't target a specific person, but eventually I can find someone who has all three bounces through tor nodes I control

Tor estimates that 2.5 million people use the network per day.

Let's assume that in a month, 10 million people use it.

Let's also assume that 80% of monthly users are not committing crimes, while the 20% who are criminals make an average of four Tor connections per month.

With those assumptions we could expect a malicious operator who controls 1,000 nodes could capture the sessions of 10,940 criminals in a given month.

For $60,000, the regime monitors Tor for a year, identifies 6,500 activists, and marches them off to the camps.

And by discrediting Tor the regime pushes the other 93,500 activists even farther underground, constraining their ability to recruit, limiting their ability to coordinate with each other, and reducing what they can publish about what's happening to their country.

What does that mean? The way I understand it you would be getting traffic correlations -- which means an IP that requested traffic from another IP and got that traffic back in a certain time period. What does that tell you, exactly, about the criminal? If you aren't looking for a specific person, how would you even know they are doing crimes?

During WW2, the British cracked the German codes. They would create pretexts for "discovering" where German ships would be, so that the Germans wouldn't suspect that they cracked their codes.

It's impossible for us to know if the US government have cracked Tor, because the world would look identical to us whether they had or hadn't. If the only evidence they have is via Tor, and the individual is a small fry, they will prefer they get away with it rather than let people know that Tor has been cracked.

These pretexts for "discovering" are a "bedrock principle" in law enforcement called parallel construction.

Random? My arse. Of the thousands of cars on the NJTP the cops just happened to pick the one loaded with drugs? A couple times a year? I don't buy it. But what are they going to say? They have someone on the inside that tipped them off? That's not going to happen.

Using those same network-health dashboards as DDoS target lists, to temporarily degrade/shut down the whole network except for your own nodes.

Also, big nodes route more Tor circuits each. Costs more to run them, and they intentionally don't function as exit nodes (to avoid the "obvious" attack) — but just having a bunch of these big nodes in the network handling only middle hops, biases the rest of the network away from handling middle hops, toward handling end hops. Which means that if you then run a ton of tiny nodes...

You can use crypto to pay if you want anonimity (this is actually the main reason I used to use bitcoin - I'd pay ISPs in Iceland to run TOR exit nodes for me without linking them to my identity).

This isn't a difficult problem. A single individual with a good job could do it.

And sure, each connection only has a very small chance of being found, but aggregate it over a year or two and you could catch half of the users of a site if they connected with a new circuit one time per day.

The second to last point is laughable since it's long been authorized in executive order that if the NSA stumbles upon information relating to criminal activity while searching for other stuff that they can report that info to the FBI.

Heck - FBI is allowed to do the same damn thing with the data they're given by the NSA. Y'know, the whole "backdoor search loophole" which amounts to laundering authorities across agencies to get access to data they wouldn't otherwise be permitted to have.

If I were an intelligence agency that had "cracked" tor -- I'd probably make sure nobody would notice I had access, so I could keep eavesdropping. Not do anything that could expose my access.

It certainly could be happening. Nothing is 100%. Nothing. Just a fact. Tor is probably pretty good at what it does.

(and keep in mind, for what we're talking about in this kind of attack, all I get access to is network contacts, not the actual messages, right?)

Assuming tor always was or became broken and is exploitable by law enforcement, authorities would try to maintain a false believe of tor's integrity so as to crack high profile cases for as long as possible.

Within this scenario, it is plausible to assume that authorities can decipher and discover information that can be used as the official pretextual charge / minor reason ("they made the mistake to use their public email address on the dark net forum") in order to not spill the beans on the actual means (here, tor being broken).

The police used self-powered GPS devices[1] to track criminals. These devices are used in various situations, such as when someone violates parole. The police don’t need to report the violation immediately. Instead, they wait for the person to re-enter their jurisdiction, then catch and arrest them.

Parallel construction wasn't tested, but the means of them catching criminals this way was tested in court.

And even catching 0.14% of pedophiles would probably be worth it to the FBI or whatever, nevermind Iran catching dissidents or whatever.

My point is that is seems very cheap to do this (I as a random staff engineer could do it myself) and catch some people. A nation state could easily catch a much higher percentage if they increased the number of logging nodes slowly and carefully and deliberately did things like use many isps and update the servers gradually etc.

londons_explore a day ago | root | parent | prev | next |

You only need to control the entry and exit node - since you know the next and previous hop for all traffic you touch, and default chains are 3 long. With circuits changing every 10 mins, within a few days you would have deanonymized at least some percentage of traffic for nearly every user.

I'd call tor broken against any adversary with a little technical skill and willingness to spend $5000.

I'm 80% sure Tor is designed as a US supported project to focus those needing anonymity into a service only governments with global security apparatus (who can grab a good chunk of internet traffic) can access.

Using Tor, like all security and privacy tools, must be balanced against what it is being used for. We will always live in a world of limited resources for policing, and systems of privacy work by increasing the difficulty and cost to deanonymize someone. They don't have to be perfect, they just have to be expensive.

If you want basic anonymity while researching someone powerful or accessing information, it's extremely unlikely anyone is going to go the lengths people are bringing up here as a way to compromise Tor. The intersection of expertise, funding and time required is too great for such a low value target.

thewanderer1983 19 hours ago | root | parent | next |

The problem with this assumption, that all possible attacks have been narrowed down to expensive only attacks i.e nation station level. These are complex systems and its not possible to prove that the only form of attacks are within these overton Windows. There may be much simpler forms of attack that aren't expensive, but the experts aren't aware of them, and therefore not focusing on. This is one of the big reasons for provably secure systems like Sel4 and other functional programming paradigms. We can't prove that all the problems are in this expensive box we put ourselves in, and all it takes is a 12 year old to discover one of these cheap attacks with a tooth pick or kids toy undermine very expensive defence systems.

Take for example, John Draper who discovered in the 60's that a Captain Crunch whistle toy could be used to make free phone calls on the telephone systems. Or the discovery of Side Channel attacks by an engineer at Bell Telephone company who noticed that a Bell Telephone model 131-B2 would produce distinct spikes for each key pressed on the oscilloscope across the room. Therefore not requiring nation station level expense to break the encryption used by Navy and Army's encryption systems. Or during the Afghan war, the US was deploying armored vehicles that they assumed would provide good protection, and would be expensive to attack by the enemy. Turned out they could make IEDs from inverted copper cheaply and within locals kitchens. That proved very successful. Or the kid who discovered he could bypass the mint screensaver by smashing random keys on the keyboard (https://github.com/linuxmint/cinnamon-screensaver/issues/354). The list of these types of cheap attacks are throughout history.

Doesn't a solid VPN service also satisfy this exact need? Tor seems to occupy a narrow niche in which you have to care much more about privacy than the average person, but not at a nation state level. I think that is how it got associated with that 2nd tier of internet crime like buying drugs on the dark web or sharing CSAM. The truly sophisticated internet criminals probably know better and the people who only really care about anonymizing themselves are probably doing something simpler.

Finding a solid one is the hard part. With tor, you kind of know what you are buying. The risks are in the open. With VPN maybe the operator is selling your data to advertizers. Maybe they are keeping logs. You kind of have to just trust them and have no way to verify.

Why not just have greater number of relays by default? Internet bandwidth tends to increase over time, and the odds of this correlation attack are roughly proportional to the attacker's share of relays to the power of the number of relays used.

So latency issues permitting, you would expect the default number of relays to increase over time to accommodate increases in attacker sophistication. I don't think many would mind waiting for a page to load for a minute if it increased privacy by 100x or 1000x.

> we need more relay operators. Can’t wave a magic wand. There’s like 8000 relays. Haven’t looked in a while.

The reason that there are so few relays and exit nodes is that everyone that runs an exit node believes, for very good reason, that they'll be opening themselves up to subpoenas and arrest for operating one. You know who never has to worry about getting arrested? Surveillance agencies tasked with running exit nodes.

Consider the two classes of relay and exit operators:

1. People who operate relays and exit nodes long term, spending money to do so with no possibility or expectation of receiving money in return, and opening themselves up to legal liability for doing so, whose only tangible benefit comes from the gratification of contributing to an anonymous online network

2. Government agencies who operate relays and exit nodes long term, spending government allocated money to operate servers, with no material risk to the agencies and whose tangible benefit comes from deanonymizing anonymous users. Crucially, the agencies are specifically tasked with deanonymizing these users.

Now, I guess the question is whether or not you think the people in group 1 have more members and more material resources than the agencies in group 2. Do you believe that there are more people willing to spend money to run the risk of having equipment seized and arrest for no gain other than philosophical gratification than there are government computers running cost and risk free, deanonymizing traffic (which is their job to do)?

If you're looking for static assets, why would you need to see the whole chain? Wouldn't a connection to a known website (page) have a similar fingerprint even if you wrap it in 3 layers of encryption? Does Tor coalesce HTTP queries or something to avoid having someone fingerprint connections based on the number of HTTP requests and the relative latency of each request?

I've always assumed that, if a global adversary attack works, you'd only need to watch one side if you're looking for connections to known static content.

I don't know much beyond the high level idea of how Tor works, so I could be totally wrong.

alasdair_ a day ago | root | parent | next |

If I don't know the whole chain (or I don't use a timing attack with a known guard and exit node) then I don't see how I'd know who sent the packet in the first place. The person in the chain would connect to a random tor guard node, which would connect to another random node which would connect to my evil exit node. My evil exit node would only know which random TOR node the connection came from but that's not enough to tell who the original person was.

Say there are only 2 sites on Tor. Site 'A' is plain text and has no pages over 1KB. You know this because it's public and you can go look at it. Site 'B' hosts memes which are mostly .GIFs that are 1MB+. You know this because it's also a public site.

If I was browsing one of those sites for an hour and you were my guard, do you think you could make a good guess which site I'm visiting?

I'm asking why that concept doesn't scale up. Why wouldn't it work with machine learning tools that are used to detect anomalous patterns in corporate networks if you reverse them to detect expected patterns.

alasdair_ a day ago | root | parent |

The point is that there aren't only two sites available on the clearnet. Is the idea that you find a unique file size across every single site on the internet?

My understanding (that may be totally wrong) is that there is some padding added to requests so as to not be able to correlate exact packet sizes.

donmcronald a day ago | root | parent |

> Is the idea that you find a unique file size across every single site on the internet?

Not really. I'm thinking more along the lines of a total page load. I probably don't understand it well enough, but consider something like connecting to facebook.com. It takes 46 HTTP requests.

Say (this is made up) 35 of those are async and contain 2MB of data total, the 36th is consistently a slow blocking request, 37-42 are synchronous requests of 17KB, 4KB, 10KB, 23KB, 2KB, 7KB, and 43-46 are async (after 42) sending back 100KB total.

If that synchronous block ends up being 6 synchronous TCP connections, I feel like that's a pretty distinct pattern if there isn't a lot of padding, especially if you can combine it with a rule that says it needs to be preceded by a burst of about 35 connections that transfer 2MB in total and succeeded by a burst of 4 connections that transfer 100KB combined.

I've always assumed there's the potential to fingerprint connections like that, regardless of whether or not they're encrypted. For regular HTTPS traffic, if you built a visual of the above for a few different sites, you could probably make a good guess which one people are visiting just by looking at it.

Dynamic content getting mixed in might be enough obfuscation, but for things like hidden services I think you'd be better off if everything got coalesced and chunked into a uniform size so that all guards and relays see is a stream of (ex:) 100KB blocks. Then you could let the side building the circuit demand an arbitrary amount of padding from each relay.

Again, I probably just don't understand how it works, so don't read too much into my reply.

The issue that TOR has is that it's a layered routing concept that won't respect ASN based spreading/scattering of traffic.

Circuits are temporary but the traffic is not scattered across the network to make MITM fingerprinting of request/payload sizes/timestamps impossible.

A typical MITM like the FBI surveillance van next door can identify you by observing the network packets and by _when_ they were requested and by _how large_ the payloads were. There was a famous court case where this was enough evidence to identify a user of an onion service, without the FBI having access to the Wi-Fi of the user. But they had access to the exit node logs that were encrypted, the pcap logs to the onion service from that exit node, and the encrypted Wi-Fi packets of the user.

(Also TLS lower than 1.3 and SNI related problems are relevant here, because DNS TTL 0 effectively makes everyone's privacy compromised, shame on you if you set a DNS TTL to 0)

My point is that with more randomized hops across the network and across ASNs it would be less likely that a threat actor can control both guard and exit nodes.

(Assuming that they parse RIR datasets to map organizations across ASNs, which the datasets already provide)

The problem is also that different network stack implementations have different MTU values and different TCP headers.

There's a lot of tools available that can fingerprint different applications pretty well these days. For example, Firefox and TOR Browser can be fingerprinted because of their custom network library that's OS independent.

It gets worse if you use a DSL2 connection with scaling because that will uniquely make your packets fingerprintable because they have a specific MTU size that's dependent of the length of the cable from modem to the next main hub. Same for cable internet, because the frequencies and spectrums that are used are also unique.

(I'm clarifying this, because an FBI van not having access to your Wi-Fi still has access to the cable on the street when there's a warrant for surveillance / wire tapping issued)

Yeah those were early days for Tor but I don't think scale changes anything. If you're using Tor because you think it is private, you have fooled yourself.

The skilled labor to set that all up, especially in a way that TOR won't notice and shut you down will be worth much much more than $5k.

People that have such a sophisticated and resourced team actively hunting them down, likely know about it, and are using many additional layers of security on top of TOR. Even just for personal use out of curiosity to "see what the darkweb is," I used 1-2 additional methods on top of TOR.

It'd be ten times that cost, easily. You have to buy data volume.

Also since you aren't targetting specific people, rather specific interests, it'd be easier to setup an irresistible site serving content of the vice of interest. It can even be a thin wrapper on existing sites. Do you only need to control entry nodes in that case? You'll return user-identifying data in headers or steganographically encoded in images and since you control the entry node you can decrypt it. It doesn't work for a normal (unaffiliated) entry node but since your entry node is in collusion with the server I think this works.

Might one mitigating possibility be to use a VPN that uses padded and rate limited packets, so that it is always sending and receiving user_defined bit rate and your real traffic would be traffic shaped to take priority but not exceed the padded streams? Maybe this assumes one is running their own tor daemon on a server somewhere and the vpn terminates on that node. I assume this could be done with tc sch_htb class shaping or perhaps sch_cake and tagging packets with iptables mangle rules and two never-ending bi-directional rsync streams reading /dev/urandom or big random files.

e.g.

    Port 873 (native rsync) bulk traffic, low priority
    Port 3128 (squid mitm ssl-bump proxy) high priority

Federal agencies operate enough exit nodes to make Tor use risky at best. I have no idea if they have since implemented some feature to prevent this but if not I would stay far away from Tor if you're planning to do illegal things. There's also the risk of trusting service operators to secure any PII you expose on marketplaces.

Not that I think the Fed's would blow their cover to hunt down people buying drugs but still seems stupid to trust.

“The western governments run most of the exits” is one of those things everybody “knows” but rarely backs up.

The list of all relays is public knowledge by design. There’s contact information attached to relays. The big operators are known individuals and organizations. They contribute. Interact.

Which ones are actually the governments doing bad things against their citizens? It’s hard to tell? Then why do you make such claims?

Relays that observably do bad things are removed from the network all the time. Are those ones the government? Tor seemingly has a reasonable handle on the situation if that’s the case.

If the fed is doing correlation attacks, why would they run relays at all? “Just” tap the IXPs near major hubs of relays. Or heck, get data from the taps you already had. Silent and more widespread.

Pushing people away from tor potentially makes it even easier to deanonymize them, depending on the adversary model assumed.

I still think the IC, and especially the state department, benefits from having Tor fulfill its actual design goals most of the time. There are operations and state department goals that can benefit from Tor working properly. It's the same with encryption in general -- the IC benefits from there being strong and bug-free crypto implementations. That they have in the past backdoored some of them doesn't change that they've also hardened others. I'm sure they come up with and deploy various attacks on Tor all the time, same with foreign nations (whom the state department would like to thwart). I'm skeptical though that they can do working attacks at any time and against any set of people.

As for secrets? We probably have to distinguish a bit between secrets/data at rest vs. secrets/data in transit. I could well imagine that a good balance between security and privacy could require some tradeoffs when it comes to data in transit.

I browse social media sites like Facebook and Reddit using their onion services. I was sick of seeing ads pop up that were clearly based on tracking my general browsing activity through IP correlation, tracking pixels and embedded “like” buttons. So now I block all cleartext Facebook/Reddit traffic completely.

Using Tor this way doesn’t anonymize me—on Facebook at least, I’m logged in under my own account—but it limits the profile Meta builds on me to the union of what it directly observes on Facebook and what it can purchase through data brokers. Ever since I started doing this, I’ve noticed a huge drop in relevance in my Facebook ads, so apparently it’s working. When the ads become suddenly relevant again (which has happened a few times), it exposes an information leak: usually a credit card purchase that Meta must have obtained from either my bank or the shop vendor and tied to my identity.

Using a VPN could theoretically provide the same benefit, but in practice Facebook tended to temporarily lock my account when using a VPN and Reddit blocks VPN traffic completely. So I stick to the onion services, which are run by the websites themselves and so are less likely to be treated as malicious traffic.

If you use these platforms, I recommend bookmarking their onion sites in Tor Browser and using it as your primary interface to them for a while. Then, if you don’t find it too inconvenient, start blocking the non‐onion versions of the sites on your network.

I think it's prudent to point out that the article's title is quite 'clickbaity', but to address it directly, the correct answer is (as it usually is) is 'it depends'. In my view, it depends on the answer to the question 'safe for who?', i.e. what is the threat model to which you are trying to guard against? If it's the US, then of course not, as the code is well-known to the US and I would expect that they have known vulnerabilities that they can leverage to ascertain the users of their service. The fact that TOR is, 'on paper', non-governmental doesn't really matter these days with the merging of private and public (and non-affiliated open-source communities) inside the security community. I would say that even the fact that it's open source isn't much of guard against such attacks, given that it relies on proficient oversight (which many eyes may not guarantee). Against other 'nation state' type adversaries - I'd wager that the more prominent who have the capacity to host a large number of relay nodes, and have access to very large computational power, will find it possible to decode portions of the TOR traffic. Against less technically proficient adversaries, such as 'run of the mill' police forces and minor nation states I'd go so far as to say it might be secure but only if you are using it for something uninteresting to them, but I ask 'how hard is it really to do a man in the middle a TOR relay?', and in terms of the most general case, 'what about the endpoints?' which of course aren't secured via TOR. Ultimately the best defense against 'snooping' in my view is to use a pre-agreed communication protocol which is undocumented and is known only between the communicators and is unusual enough to be hard to recognize or hard to work out what it means (preferably with a key to those communications known only to the two parties), but then I suppose you could use any communication protocol...

You are under no legal obligation to assist police in their investigations.

Absolutist statements about services like TOR or VPNs are often not helpful. It's highly contextual to the threat. If the threat is a state actor it's likely nothing, TOR included, can preclude them from determining things about you that you would prefer them not to know.

Some specific state actors operate TOR entry and exit routers and can perform analysis which is different to others who just have access to the infra beneath TOR and can infer things from traffic analysis somewhat differently.

I have never been in a situation where my life and liberty depended on a decision about a mechanism like TOR. I can believe it is contextually safe for some people and also believe it's a giant red flag to a lead pipe and locked room for others.

This isn't written in the most confidence inspiring way

But the things that do inspire confidence:

Tor is updated against vulnerabilities pre-emptively, years before the vulnerability is known to be leveraged

Tor Project happens to be investigating the attack vector of the specific tor client, which is years outdated

They should have just said “we fixed that vulnerability in 2022”

with a separate article about the old software

While it has been fixed for years it was not a case of using old software from what I am reading.

The vulnerability is mitigated by shifting the economic incentives, not fixed by making it impossible. It can't be fixed without a completely different network design, like in Mixminion or Katzenpost. Someone suggested I2P, but it's mostly fundamentally the same as Tor. It uses unidirectional tunnels, which might help.

...We are writing this blog post in response to an investigative news story looking into the de-anonymization of an Onion Service used by a Tor user using an old version of the long-retired application Ricochet by way of a targeted law-enforcement attack.

...From the limited information The Tor Project has, we believe that one user of the long-retired application Ricochet was fully de-anonymized through a guard discovery attack. This was possible, at the time, because the user was using a version of the software that neither had Vanguards-lite, nor the vanguards addon, which were introduced to protect users from this type of attack. This protection exists in Ricochet-Refresh, a maintained fork of the long-retired project Ricochet, since version 3.0.12 released in June of 2022.

It's true that a majority is from the US government through various funding schemes and grants. They're very transparent about their funding and ongoing efforts to diversify.

And they want to do this to everybody, all the time. This might or not bite you in the future. You seems to imply that since nothing immediately bad is happening by using slightly bad security, then it’s OK and we shouldn’t worry about it, since Mossad is not after us. I think that we should have a slightly longer view of what allowing NSA (et al.) to know everything about everybody would mean, and who NSA could some day give this information to, and what those people could do with the information. You have to think a few steps ahead to realize the danger.

Wonder what has replaced “Xkeyscore” given the wide adoption of TLS. I know ISPs, especially national ISPs like AT&T (see: titanpointe - 33 thomas st, nyc) would feed data to NSA since traffic at the time was mostly via http (rather than https). I suppose the unencrypted dns queries are still useful (although DNSSEC is supposed to defend against snooping/deep packet inspection)

yupyupyups a day ago | root | parent | next |

>Wonder what has replaced “Xkeyscore” given the wide adoption of TLS.

Cloudflare is a US-based company that does MITM attacks on all traffic of the websites that it protects. It's part of how their DDoS mitigation works.

Many people still use large US-based mail providers such as Outlook or Gmail.

Many large services use AWS, GCP or Azure. Perhaps there are ways for the NSA to access customers' virtual storage or MITM attack traffic between app backends and the load balancer where TLS is not used.

itscrush 20 hours ago | root | parent | next |

Load Balancing && WAF or CDN enablement usually suggests at least a decrypt step or two in the HTTP(s) chain. WAF for layer7 payload inspection, or the default wildcard cert'ing your Cloudflare site for instance.

There's also significant aggregation of traffic at handfuls of service providers amongst service categories, all generally HTTP(s) type services too ... Mail, CDN, Video, Voice, Chat, Social, etc. Each of these are still likely to employ Load Balancing & WAF.

Most WAF/Load Balancing providers have documentation about when/where to perform decrypt in your architecture.

How many Cloudflare sites are just using the Cloudflare wildcard cert?

From there, plenty of 3 letter agency space to start whiteboarding how they might continue to evolve their attack chain.

snewman 21 hours ago | root | parent | prev | next |

Often the connection between the load balancer and app backend also uses TLS. I've operated a large / complex service on AWS and all internal communications at each level were encrypted.

Of course, in principle, a cloud provider could tap in anywhere you're using their services – ELB (load balancer), S3, etc. I presume they could even provide backdoors into EC2 instances if they were willing to take the reputational risk. But even if you assume the NSA or whoever is able to tap into internal network links within a data center, that alone wouldn't necessarily accomplish much (depending on the target).

sophacles a day ago | root | parent | prev | next |

It is MITM, but is it an attack? Literally the website owner hires Cloudflare explicity to decrypt and filter the traffic. Attack implies that it's unwanted behavior, yet the reality seems to imply that its wanted behavior by the site owner at a minimum, although continued use of the site by visitors also suggests that they want that behavior (or they'd go elsewhere).

Lots of juicy Internet protocols are still running in cleartext. OCSP, for example, and DNS, as you noted.

Start an NSA cutout called Cloudflare. Configure sites to use an SSL/TLS connection to Cloudflare, then a separate SSL/TLS connection from Cloudflare to your actual machine. Then have the marketing team call it "Strict" encryption. Make it free so everyone uses it.

treebeard901 15 hours ago | root | parent |

It is also a lot easier since ceetificate pinning has fallen out of favor. Many sites use LetsEncrypt. The Certificate Authority system itself is not reliable.

In a way it is the perfect solution from a Govt perspective. Other countries have systems at this scale and larger. China for example.

yencabulator 6 hours ago | root | parent |

What makes the CA system reliable is browsers insisting on Certificate Transparency before trusting a cert. If an attacker creates an evil cert by stealing the ACME verification traffic, there's a permanent record of it.

IIRC there were a lot more options by the time of the Truecrypt-Veracrypt shift.

No? Any modern disk encryption system with a strong passphrase (basically, anything but default-BitLocker) is very effective against "they have your physical machine and it's off" for any known, current adversary. And, the basic cryptography in use is common, robust, and proven enough that this is probably true even if your tinfoil hat is balled quite tightly.

Where modern research effort goes is into protecting against "they HAD your physical machine and they gave it back to you" or "they got your machine while it was on/running" - these are much more difficult problems to solve, and are where TEE, TPM, Secure Boot, memory encryption, DMA hardening, etc. come into play.

How does that work technically, if I am connecting with SSL?

The only thing I see is seeing which IP addresses are using Tor, when, and how much traffic exchanged, but mostly it will be a bunch of reused residential IPs? If you know who you are looking for anyway better to work with their ISP?

With the exit nodes, you know which IP addresses are being looked up. You might get an exit node IP when investigating a crime say. Raid that person, but can you find anything more?

This isn't an argument, but a question.

Does Tor Browser Bundle currently ship with Ublock Origin installed and on by default?

It would be irresponsible for it to do so. Ad blocker lists can inject scripts into web pages which could compromise user privacy.

jancsika a day ago | root | parent | prev |

In that case we're talking at cross-purposes, so I'll reserve judgment.

I'm concerned with what let's call Gorhill's Web-- that is, the experience glued together by gorhill's Ublock Origin that is viewed by the vast majority of HN commenters on a day to day basis.

What you're describing is the Web-based Wasteland that is experienced by the vast majority of non-technical users who view the web without an ad blocker.

Encouraging Wasteland users to use TBB may well be an overall improvement for them. But there are more and more popular parts of the web that are practically unusable without an ad blocker-- e.g., fake download buttons, myriad other ad-based shenanigans, multiple ads squeezed into short pieces youtube content that ruins the music, etc. And there's an older segment of the population who at I cannot in good conscience move away from Gorhill's Web.

If Tor uptake somehow spikes to the point that some services can no longer get away with discriminating against exit nodes, then great! But in the meantime, I and many others have solid reasons for encouraging more and more Ublock Origin use among a wide variety of users.

And as you point out, there are technical reasons why the ad blocker lists are at odds with TBB design goals. Thus, I find the top poster's "cui bono" comment low effort and unhelpful.

1. It's fun. Playing with these technologies is entertaining and will learn you some good stuff about the networking and the encryption and what not.

2. Tor allows reception of unsolicited TCP/IPv4 traffic if you are behind a NAT you can't open ports for, because your connection to the network is initiated on your side. This is nice, especially with increasing prevalence of CGNAT.

3. Something my niece stated when I talked to her about it, who I disagree with: Many countries have a notion of upstanding citizen enforced by well funded and maintained violence-monopoly actors (R) that are not equivalent to what the majority of citizens actually do (S). R minus S is T - the tolerance gap. Things that allow T to exist include lack of will to prosecute, general social acceptance of things that were not acceptable years ago, etc. All things that are quite mutable. If your activities fall into T, privacy-enforcement tech benefits you if R and S might change in the future.
