The sextortion email scam last month that invoked a real password used by each recipient and threatened to release embarrassing Webcam videos almost certainly was not the work of one criminal or even one group of criminals. Rather, it’s likely that additional spammers and scammers piled on with their own versions of the phishing email after noticing that some recipients were actually paying up. The truth is we may never find out who’s responsible, but it’s still fun to follow some promising early leads and see where they take us.

I recently heard from a source in law enforcement who had a peculiar problem. The source investigates cybercrime, and he was reaching out for advice after trying but failing to conduct undercover buys of stolen credit cards from a well-known underground card market. Turns out, the cybercrime bazaar’s own security system triggered a “pig alert” and brazenly flagged the fed’s transactions as an undercover purchase placed by a law enforcement officer.
