A Ukrainian man who tried to frame me for heroin possession has pleaded guilty to multiple cybercrime charges in U.S. federal court, including credit card theft and hacking into more than 13,000 computers.

Sergey Vovnenko, 29, entered a guilty plea in Newark, New Jersey to charges of aggravated identity theft and conspiracy to commit wire fraud. Prosecutors said Vovnenko operated a network of more than 13,000 hacked computers, using them to harvest credit card numbers and other sensitive information.

When I first became acquainted with Vovnenko in 2013, I knew him only by his many hacker names, including “Fly” and “Flycracker,” among others. At the time, Fly was the administrator of the fraud forum “thecc[dot]bz,” an exclusive and closely guarded Russian language board dedicated to financial fraud and identity theft.

After I secretly gained access to his forum, I learned he’d hatched a plot to have heroin sent to my home and to have one of his forum lackeys call the police when the drugs arrived.

I explained this whole ordeal in great detail last fall, when Vovnenko initially was extradited from Italy to face charges here in the United States. In short, the antics didn’t end when I foiled his plot to get me arrested for drug possession, and those antics likely contributed to his arrest and to this guilty plea.

The aggravated ID theft charge to which Vovnenko pleaded guilty carries a mandatory two-year sentence. The other charges he copped to will lengthen his sentence and include fines. His sentencing is currently slated for May 2, 2016. The indictment against Vovnenko is here (PDF). A copy of his plea agreement is at this link (PDF).
