I believe that tor metrics counts when a connection starts, not when a connection is _established_

This is a important difference, because if there is active DPI that is shutting down a connection before handshake can happen, it will inflate the numbers massively.

I suspect what actually is happening is a ISP in UAE has deployed a DPI system that can detect the Tor TLS signature

Holy shit! -4 to that? I don't mean to get all meta, but really I must be further out of touch than I realized.

I didn't downvote you, but I can imagine two different reasons that people might have done so: (1) They want to emphasize that there are lots of reasons to use Tor other than political dissidence and that Tor use should be normal or common for lots of people in lots of situations. (2) They feel like the role of tools like Tor in facilitating political dissidence is overstated and that you were implying that Tor will…

I appreciate the poetry but blocking Tor is a lot easier than preventing the wind and some governments (e.g. China) successfully do so.

Blocking Tor is one thing. But once people have made an effort to use Tor, you have lost as a regime.

I don't know what this means. People in the U.S. use Tor, has it lost as a regime? What does "lost" mean in this context? Some moral authority? All moral authority? I think we can say that as governments do in fact continue to exist while their citizens use Tor, that the statement is sufficiently vague that it's meaningless.

This sounds convincing, a 25-fold spike in real users seems unlikely.

If your theory is correct, then the title is slightly misleading.

And even if they were only counting successful connections, connections != users.

It's a matter of intent. If people are willing to try to get around oppression, they have already indicated their intent to strive for better. Maybe it takes a year, or 5, or 10, or more, but people will group and work for freedom.

That is my point.

Tor isn't safe from state-level attackers, as demonstrated by the Sybil attack launched by Carnegie Mellon the other year.

Do you have a link to the paper? "Sybil attack" is a rather large category of attacks and I'm curious about the specifics of this particular one. In particular, certain vulnerabilities can still be prohibitively expensive for use in dragnet-surveillance.

It was never released: http://motherboard.vice.com/read/carnegie-mellon-university-...

Just out of curiosity: How is Tor looking these days, security-wise? Does someone have a recent analysis of the attacks Tor is facing from state-level attackers currently? Just wondering if any new threats to Tor have come up in the recent years that hadn't been considered before stuff like Snowden happened.

My impressions from the research community have been that the consensus is 1. Using Tor is more private (and possibly more secure) than a VPN or nothing at all, 2. Tor will not protect you from a targeted attack by a well-funded, state-level adversary, 3. It may or may not defend you against more dragnet types of attacks, depending on the state of the cat-and-mouse between offense and defense (it most likely will protect you on any particular session, but the more you use Tor, the more likely you'll use it while an attack is viable in the wild).

So far though, the overwhelming majority of attacks on Tor users comes from things that aren't Tor itself --- e.g. Firefox vulnerabilities, timing side-channels on when the user was home, etc. Additionally, if you're not doing anything illegal, you're less likely to be targeted on Tor. Not that this is to say "if you're not doing something illegal you have nothing to hide!", just that your adversaries are likely not powerful or motivated enough to target you on Tor if what you're doing isn't illegal. Even in places like China, where every attempt to block Tor is made, they typically don't spend much effort in targeting those who do try to use Tor. This means if your motivation for Tor is to do things like stop web site trackers, it's not only a good option, it's probably the best available.

In the land of Tor can you distinguish the difference in any meaningful way? I agree generally but I don't see how Tor could differentiate.
