Tor Project Accuses CloudFlare of Mass Surveillance, Sabotaging Traffic (softpedia.com)

An anonymous reader writes: Tensions are rising between Tor Project administrators and CloudFlare, a CDN and DDoS mitigation service that's apparently making the life of Tor users a living hell. Tor administrators are saying that CloudFlare is making Tor users enter CAPTCHAs multiple times, tracking their Web sessions, and sharing data with other companies. Additionally, a study by some UK and US researchers found that are 1.3 million websites blocking access to Tor users, 3.67% being Alexa Top 1000 sites.

      Yeah, this seems to be a result of one of these factors:
      a) Tor lets good people do good things anonymously so as to avoid persecution
      b) Tor lets bad people do bad things anonymously so as to avoid persecution

      In this case, a lot of site would either legitimately block Tor or add extra hoops to stop (b). The same thing that lets some dude avoid censorship in his country also lets another dude attack somebody's site while obscuring his origin.

      What I would do is to increase the presence of US law enforcement on Tor.

      Tor was created by the US government, not for privacy but for freedom of political and cultural speech under oppressive regimes. The whole premise of Tor was that a citizen of a repressive regime would be able to access the internet as if they were in a free nation; they would appear on the internet as being from there, and the only people who would have enough network access to identify them would be the people on the western side.

      Those people are the "legitimate" traffic. The reason why libraries sign up as Tor nodes is to grant people under repressive regimes to view the world as it is viewed from a western library.

      It is hilarious the people who think Tor would be some sort of "privacy" service that would shield their browsing from the US Government. The whole premise was to create a safe space for communication that was locally banned, but legal in the US and like-minded States. In my opinion, if people want to prevent Tor from being banned as a source of abuse, all they have to do is limit its use to the intended use. If they want it to be broadly used for other things, eventually it will be blocked from accessing almost anything, because DoS attacks are a thing.

      And the Internet (ARPANET) was created because... who gives a shit, really? You talk like TOR is some kind of service like Facebook, shut it down and it's down. It's not, it's a piece of software. You can run TOR even if you ban all US nodes from touching your circuit, as long as there's someone out there willing to be your relay. That's kinda the whole point, to distribute the traffic through multiple nodes that aren't likely to collude to decrypt your traffic. So I can talk to TOR entry guard at a university in Germany that talks to a relay node in China that talks to an exit node in the US. Each link in the chain protects me against some abuse, including US abuse. Don't think the world will forgot the NSA's transgressions any time soon. Make a US panopticon if you want, but nobody will trust it.

    With Tor, I can specifically set which country I want my exit node to be from, and I have a large selection. If I want, I can select a single exit node and stick with it until the IP is blocked.

    This is useful for scanning, brute forcing, exploitation, ex-filtrating data, or just trolling online. Anything nefarious that I don't want linked back to me easily. Malware using Tor for C&C traffic doesn't help the situation.

    Bad actors give Tor a bad rap, even if does a ton of good for countries with repressive regimes. Thanks to negativity bias, people block Tor unless they have a specific reason for allowing it.

  6. This is a technical malfunction, not surveillance. by Striek · · Score: 2

    CloudFlare is not targeting Tor users. They aren't doing anything not considered best practices in general and practised all over the net. Showing a CAPTCHA to a Tor user is used in many places, including Google and Yahoo, who employ this method without irking people. The issue is that the technology CloudFlare is using to accomplish this is malfunctioning, and not that they are targeting Tor users.

    So far, the Tor project hasn't accused them of surveillance publicly. That would be overkill. Adding a cookie to a web browsing session (which I presume is so that session is not subjected to such measures in the future) is hardly mass surveillance. Tor are being their usual anal selves and refusing to compromise. This problem is a technical malfunction, not mass surveillance of CloudFlare users.

    They do have a point that CloudFlare can be notoriously difficult to resolve problems with, though. CloudFlare can be just as anal as Tor.

    I've been using Cloudflare for a few years, and they've helped me handle traffic and abuse from my one-server site and have never been a problem or expensive. Nor have they been malicious. I also have some Open Source projects like FreeDV.org going through Cloudflare.

    One of the things they do is protect me from web attacks. It's an unfortunate fact that Tor really is used for web attacks.

    Obviously, if there is a problem with their capcha, they need to fix it. I think it's perfectly fair for someone who is approaching the site through a known attack vector to have to pass a capcha once.

    Regarding cookies, you're always going to get one on my site, whether you are using Tor or not, to support logins. HTTP isn't session-based and you need cookies to simulate sessions, so that you can have logins and dispense privileges where appropriate.

An unpublished exit node would have just as many attacks appearing to originate from it as a published exit node, and would make the blacklist in the exact same amount of time.

  19. They're in a no-win position. by Mal-2 · · Score: 2

    Sites that accept Tor connections find themselves subjected to many problems. Just one of them is being unable to identify the source of a connection to keep one person from setting up large numbers of accounts. This is happening on Voat, with a few certain users signing up hundreds of times then spamming the place -- while the rest of us are limited to one account per IP address. Got two people at your house who want accounts? Too fucking bad. Yet it does abs-olutely nothing to stop the Tor and proxy users. There is a very vocal contingent (I can't say how numerous they are) that insists that without the anonymity of Tor and proxies, they won't visit at all. These are not problem users, either, they're well-behaved. They might be spewing vile shit in /v/niggers or /v/FatPeopleHate, but they're not abusing the service and crossposting where nobody wants to see them. On the other hand, you have people like me, who want the crapfloods stopped. If it takes banning Tor and proxies, I'm afraid I have to say I'm for it -- though if it can be accomplished by less severe methods, that would be better. So far, management has taken the other side (doing nothing as best I can tell), so I've largely moved on. Rule #0 of any service should be "no unenforceable rules". If they can't or won't enforce the "one account per person" rule on Amalek and the Men's Rights Activists, then they shouldn't enforce them on anyone.

    4chan, vile as it was, did not allow posting from proxies the last I checked (which would be over a year ago, now) because of the inability to stop the crapfloods. 8chan makes Tor users solve CAPTCHAs every three to five posts instead of once a day. There may actually be a good balance between preserving functionality for good Tor users while preventing abuse by the bad ones, but if a site as dedicated to free speech as Voat can't find it, then sites that aren't so gung ho about free speech are just going to say "screw it, block them". Can they really be blamed?
