I would imagine the professionals are using other peoples cracked wifi networks, then routing through tor or a similar onion routing system, eventually hitting a VPN endpoint on some anonymous-hosting account in russia, etc etc.

The truly paranoid might like to rent a botnet and build their own tor network on top of it or something like that.

In short: the fundamental nature of TCP/IP is such that if you are sufficiently motivated, and dont mind horrible latency, even the FBI/tptacek cant identify you.

I'm thrilled to report that it isn't my business at all to track down people on the Internet, and so I am not a good standard for what is and isn't feasible vis a vis IP traceability.

We break apps and build products and that is just about it. (We've also never done business, to my knowledge, with the government.)
