I mean one market leaking his IP is possible (but still strange, as i bet many hackers tried to get into SR just for the btc). But so many markets leaking IPs ?!? I don't buy it. How did they seized it?!?
Doesn't anyone wonder?!?
If I had to guess I would say the feds started to run a lot of tor nodes to break the tor protocol.
Edit: OK I just found on the fbi website that they infiltrated the staff. this might explain SR but still not explaining the other markets.
Edit2: I've been almost through the document and it's like a fucking joke. He used his real Address to lease the servers, he fucking used GOOGLE (GOOGLE!) for his email domain (every shitty email provider has more privacy than GOOGLE) and used it for his serverlogs. this just reads like a joke ...
Edit3: Ok, I've read the whole document, there is no info on how they obtained the IP.
SR2 probably told other people how to host dark net markets and then every market hosted at that server location got busted.
