Ask HN: Cyber criminals of HN, what is your tech stack?

I am reading American Kingpin, a non-fiction account of the Silk Road and its founder, Ross Ulbricht. Although the book doesn't go very deep on the technical aspects of running what was basically an e-commerce website, there is some basic information:

- php - mysql - running on a server behind the TOR network - pgp encrypted chat for employees to talk - bitcoin for transactions - bitcoind (php?) library

It made me hungry for some more details.

In any case, those of you doing things considered illegal by your government, what is your tech stack? Please also give us a vague account of what you are doing.
