Law enforcement allegedly managed to identify servers and users who used the anonymization service Tor.
2 things:
This has never been unknown, this is one of the fundamental attack vectors against TOR, the IM protocol seemed to make correlation easier due to its real time nature.
They added a protection layer called Vanguard, to ensure the internal exit nodes were fixed to reduce the likelihood that you could track a circuit with a small number of compromised internal exit nodes. This seems like it would help due to reducing likelihood of sampling.
Other state actors might try, but they're not in the same league in terms of resources, IIRC there are a LOT of exit nodes in Virginia.
tl;dr - The protocol is mostly safe, it doesn't matter if people try to compromise it, the nature of TOR means multiple parties trying to compromise nodes make the network more secure as each faction hides a portion of data from the others, and only by sharing can the network be truly broken. Good luck with that.
