Very interesting article about how the founder of the largest forum for selling stolen data was found. In this case, leaks and a serious attack on his site helped to find his real name, but the researcher was able to link many pompompurin's accounts even without that.
Which is a good reminder: use different usernames and emails on different services. And using an email with your real name in the address is not a good idea if you want to stay anonymous :)
Pompompurin and BreachForums
Something more than a year has passed since Pompompurin was detained by the FBI. I did this investigation on him when it happened, and now after some time, I’ve decided to make it public here. The goal of the investigation was simple, I just wanted to find who pompompurin was, how he became the creator of BF (BreachForums) and how he ended up detained (bad OPSEC as usual :)). Keep in mind that everything you are about to see is Open Source.
