Denuvo’s notorious anti-piracy tech used to be seen as uncrackable. It held up against hackers’ best efforts for years, contorting itself into obtuse new shapes every time anybody broke through. In 2016, a Bulgarian hacker calling himself Voksi came along with a breakthrough that revitalized the whole Denuvo cracking scene. He’s been a pillar of it ever since. Now he’s in deep trouble.

In a post today on CrackWatch, a subreddit dedicated to removing DRM and other copy protection software from games, Voksi explained the sudden outage of the website of his hacker group, REVOLT. Yesterday, he got arrested, and the police raided his house.

“It finally happened,” Voksi wrote. “I can’t say it wasn’t expected. Denuvo filed a case against me to the Bulgarian authorities. Police came yesterday and took the server PC and my personal PC. I had to go to the police afterwards and explain myself.”

In a statement sent to Kotaku, Denuvo said that Voksi’s arrest came about through the dual efforts of Denuvo parent company Irdeto and the Bulgarian Cybercrime Unit. “The swift action of the Bulgarian police on this matter shows the power of collaboration between law enforcement and technology providers and that piracy is a serious offence that will be acted upon,” said Irdeto VP of cybersecurity services Mark Mulready.

Denuvo’s statement also included a quote from the Bulgarian Cybercrime Unit, which said: “We can confirm that a 21-year-old man was arrested on Tuesday on suspicion of offenses related to cybercrime and that computing equipment was confiscated. Our investigations are ongoing.”

Voksi declined to reply when reached for comment by Kotaku, but on Reddit he lamented that this Denuvo-cracking days are almost certainly behind him. “Sadly, I won’t be able to do what I did anymore,” he said. “I did what I did for you guys and of course because bloated software in our games shouldn’t be allowed at all. Maybe someone else can continue my fight.”
