Thanks for sharing, Collin.  Those graphs are very interesting.  What the hell is going on???

Embarrassingly, I went straight to the most romantic hypothesis and then worked my way back elsewhere, IRC and Twitter. A few of these prospects could be reasonably addressed through the trends of the top fifty countries, illustrated here: http://cda.io/r/tor_mystery_2013.png

Few other points of conjecture that came up:

   - I would infer based on no increase occurring in Iran that the Tor
   version being run by the agent is pre-2.4; Iran continues to implement
   countrywide DPI against Tor's SSL handshake, which was fixed for the moment
   in ticket #8443. Whether it's circumvention or malware, I would trust it
   would hit Iran.
   - As Runa notes, attempting to correlate with censorship is not strong,
   I would propose however that based on relative growth, a better indicator
   is level of development (ehem, piracy) and geography. I might be passing
   over someone, but it isn't until you get to Japan (40th) that you run into
   what is traditionally called a highly-developed state (all apologies for
   the terrible phrasing of this).
   - Pirate Browser with Tor was released when, August 11th or 12th? I
   would expect we would see a more gradual and less synchronous incline if it
   were natural adoption patterns (short of an autoupdater).

  A) The change in user counts for each country should be proportional

I would also look for piracy and software update rates.

I culled the list at 1,000 users on either dates, there were a few countries that cropped up with new users, like Anguilla. Macedonia and Bosnia are also interesting toward this, regionally and going from a hundred to a thousand.

Look for Muslim countries in the chart.

It's not.

Like, Hack the planet, bro.

So I think we are left with one unfortunate, not Israeli conclusion. Is there an example of such fine grain statistics of botnet growth tagged with date and country? Seems like a pretty solid research dataset for someone.

Cordially,
Collin
