Unofficial Tor Community

Link to tor project (they made the icon I grabbed, and tor itself of course): https://www.torproject.org/

This is a community to discuss the tor project and your experience with tor, tor browser, etc.

Rules are generally: be nice, don't be bigoted, etc.

Only seems fair that an infosec instance should have a community about one of the most well known anonymity tools :)

A Turk was telling me about a peaceful demonstration he attended, in Turkey. He said police surrounded the protest. Then someone in plain clothes threw a stone at the police. One of the demonstrators noticed that the guy who threw the stone had handcuffs in his back pocket. IOW, a cop posing as a demonstrator threw a stone in order to justify the police tagging the protest as “violent” so they could shut it down.

So of course the question is, to what extent are bad actors on Tor actually boot lickers who are working to ruin Tor for everyone?

There are many situations where gov-distributed public information is legally required to be open access. Yet they block Tor.

To worsen matters, the general public largely and naively believes it’s correct to call something as “open access” when in fact there are access restrictions in place.

The resource should work like this:

  1. User supplies an URL
  2. Robot tries to access that page from a variety of different countries, residential and datacenter IPs, Tor, various VPNs, different user-agent strings, etc.
  3. Report is generated that reports the site as “openly accessible” if no obsticles (like 403s) were detected. Otherwise tags the site as “restricted access” and lists the excluded demographics of people.

The report should be dated and downloadable as PDF so that activists can send it to the org behind site with a letter saying: “your website is not open access -- please fix”.

This need somewhat aligns with the mission of the OONI project, but they are not doing this AFAICT.

Update

I just read an announcement about Belgium’s “open data” law, which is basically a summary. It said something like “there should be no unnecessary access restrictions”. I’m not sure to what extent that accurately reflects the law, but it’s an example of what one country considers “open”, fwiw. From there, I would say most Tor blockades are not necessary but rather some lazy sysadmin looking for an easy job. They of course would then like to argue that it’s “necessary” to keep the baddies out.

There is a particular public hotspot where tor takes like an hour to establish a connection on. It’s stuck on 10% shows a running count of connection attempts upwards of 40.

What does this mean? Is it that the wi-fi operator is blocking guard nodes, but perhaps only a snapshot of guard nodes? When I finally connect, is it a case where I managed to get a more recent guard node than the wi-fi operator knows about?

Political parties around the world have flocked to nationbuilder.com for some reason. This tor-hostile Cloudflare site is blocking Tor users from accessing election info. This kind of sloppy lazy web administration is common.

But what’s a bit disturbing is that when I contact a political party to say I cannot reach their page because of the nationbuilder block page, they sound surprised, like it’s the first time they are hearing about web problems. So Tor users are lazy too. That’s the problem.

Tracker pixels are surprisingly commonly used by legitimate senders.. your bank, your insurance company, any company you patronize. These assholes hide a 1-pixel image in HTML that tracks when you open your email and your IP (thus whereabouts).

I use a text-based mail client in part for this reason. But I got sloppy and opened an HTML attachment in a GUI browser without first inspecting the HTML. I inspected the code afterwards. Fuck me, I thought.. a tracker pixel. Then I visited just the hostname in my browser. Got a 403 Forbidden. I was happy to see that. Can I assume these idiots shot themselves in the foot with a firewall Tor blanket block? Or would the anti-tor firewall be smart enough to make an exception for tracker pixel URLs?

To do an MX lookup over Tor, this command has worked for me for years:

$ torsocks dig @"$dns_server" -t mx -q "$email_domain" +noclass +nocomments +nostats +short +tcp +nosearch

In the past week or so it just hangs. My first thought was the DNS server I chose (8.8.8.8) started blocking tor. But in fact it does not matter what DNS server is queried. The whole Tor network is apparently blocking tor users from doing MX lookups.

Also notable that dig hangs forever. It does not timeout despite a default timeout interval of 5 seconds (according to the man page).

In the onion v2 days we had underwood2hj3pwd.onion. There were half a dozen other onion email providers but Underwood was the only one that did not have a clearnet email alias (IIRC). That was a useful feature because you could distribute an onion address to a MS Outlook or Gmail user and they could not use it to share their correspondence to you with Google or MS in the loop. They had just two options: step off the ad surveillance platform or not contact you at all. That option died with Underwood.

The other onion email services all have a clearnet translation. So if (for example) I give a gmail user this address:

foo@yllvy3mhtamstbqzm4wucfwab57ap6zraxqvkjn2iobmrtxdsnb37dqd.onion

and they are motivated to reach me, they can figure out that the corresponding clearnet alias is foo(/at/)onionmail.info and then they can use that address to send me a msg that is then shared with their surveillance advertiser. And worse, that’s less effort for them than obtaining an onion email account.

So what I do now is give an XMPP account. Since Google has abandoned jabber and MS never partook, XMPP avoids Google and MS. But XMPP is not a drop-in replacement for email. OMEMO is glitchy/buggy with pitfalls.

I would like to offer an email option. Ideally, an onion email service would offer a clearnet alias that cannot be determined from the onion address, which implies a different userid string.

What happens if an app uses UDP instead of TCP (or both UDP and TCP), and you use the torsocks wrapper script? Would the UDP connections all leak without the Tor user knowing?

I simply make a GDPR request. Write to a Tor-hostile data controller making an Article 15 request for a copy of all your data. Also ask for a list of all entities your data is shared with.

The idea is that if a website blocks Tor (or worse, uses Cloudflare to also share all traffic with a privacy offender), then they don’t give a shit about privacy. So you punish them with some busy work and that busy work might lead to interesting discoveries about data abuses.

Of course this only works in the EU and also only works with entities that have collected your personal data non-anonymously.
