Krebs has tracked the man — whom he identifies as a man called Andrey Hodirevski who uses the screen name “Helkern” — across a series of web sites, social media, and hacker forums. Krebs alleges that Helkern is the operator of a web site called Rescator, on which millions of Target credit card details are now being sold.
Krebs also found this photo of Helkern, in a Range Rover military vehicle bearing Nazi insignia:
Krebs is not saying that Helkern engineered the Black Friday hack of Target’s checkout systems. Rather, he’s alleging that Helkern is now selling the numbers from that theft. Krebs has been working with banks whose customers
are affected to trace the numbers on Rescator.
“I have no idea if Rescator/Helkern/Andrew was involved in hacking Target, but it’s a good bet that he at least knows who was,” Krebs told The New York Times
Krebs says he had a a brief online conversation with Helkern, who offered to pay him $10,000 not to run his story.
