Stealing it is probably illegal, and there’s a copyright and export regulations argument to be made around copying it.
However, my understanding of the law is that, once secrets are made public, further distributing the secrets is not illegal.
So, republishing it is probably not more illegal than running a torrent of a Hollywood movie and an Ubuntu ISO (which can run afoul of export regulations).
Note: I’m not a lawyer, and if what I said was true in practice, Julian Assange / Wikileaks would have nothing to fear from the law.
Also, there are currently hundreds of seeders (according to a popular torrent indexers) and there were probably thousands of snatches. Good luck prosecuting that many people.
