This is literally just seeing where data comes out to correlate where it goes in?

Yeah, This seems to depend on a TOR exploit (Onion Address Analysis Method Based on Multiple Timed Sync Response Messages), plus controlling a [not small] amount of TOR nodes and also Monero nodes both at the same time, plus sending these signals to correlate traffic. The examples it gave said like a 1000 malicious Tor nodes (which may very well be possible) and half of all TOR-using Monero nodes

I went through the paper pretty thoroughly, and definitely don't think the probability in the real world is as high as the theoretical percentages they give, but I'm not an expert.

Nevertheless, I sinerely hope the TOR and Monero teams both look at this, it could be serious. Especially for TOR.
