Quoting mxz+tor-anti-censorship-team--- via anti-censorship-team (2023-03-20 22:31:23)
a while ago (10.02.2023) I tried to send an email on the tor-talk mailing list but apparently it never got through as it's still awaiting approval. (it wasn't denied either, afaik)
I think tor-talk is being having less and less movement in favor of the forum[0], but we should either close the list or take care of the moderation. Sorry.
recently, there was an interesting side note on the cryptography mailing list [1]. Quote:
(People have written code to predict what continent an anonymous person using Tor is on, based on noticing over a period of time when their remote system clocks ran faster or slower, assuming that was caused by nighttime versus daytime temperatures.)
I was wondering if any of you know about this and where I could find code that does this? Any links to research and papers would be highly appreciated, too.
Especially, I'm wondering how they do this:
- via differences in the above mentioned system clock (impressive?!) - timing analysis with latency? things like lower latency in Europe as there are more tor relays around compared to Argentina. - do you need to have any prerequisites? e.g. controlling at least one node, or the exit node, or a "clear text" server/hidden service that someone connects to?
Finally, if that's the wrong list, please refer me to the right one. Thanks!

I didn't know about that. You can ask in the forum[0], maybe someone there knows about it.
