A lot of these Brian Krebs articles seem to be little more than exposés of popular services from carding forums. Of course, I don't mean to knock his investigative reporting -- he is performing a valuable public service, and some of his stories require far more complex investigative journalism than simply reading forum posts.

But I am wondering, where are all these forums that Krebs is signed up for and reading? Also, is he fluent in Russian? I know revealing the URL's might tempt would-be cyberthieves, but personally I have my own curiosity that I would like to satisfy by reading them. I suspect there is a lot to be learned just by reading those forums (which I assume are member-only and require some kind of vetting process, anyway).
