Formerly formidable anti-tamper technology Denuvo appears to be losing its battle against hackers and pirates.

As TorrentFreak reported on Friday, Creative Assembly's fantasy strategy sequel Total War: Warhammer II was pirated on its first day on the market despite being protected by Denuvo.

That's easily the fastest any group has managed to bypass Denuvo's protection.

Denuvo debuted in 2014, and quickly gained its reputation as anti-tamper market leader after it took hackers more than a month to crack Dragon Age: Inquisition – a lifetime in hacking terms. Just Cause 3 remained uncracked for a whole year.

However, last year hackers appeared to be getting the upper hand on the technology, despite Chinese cracking group 3DM declaring that Denuvo was probably uncrackable, and that PC game piracy would soon be a thing of the past.

Doom, Rise of the Tomb Raider, Inside were all cracked, and earlier this year Resident Evil 7 fell in less than a week.

Later, Rime and Tekken 7 were cracked in a few days each.

In February, Denuvo marketing director Thomas Goebl told Eurogamer that some protection was better than nothing.

"Please note that we always position our Anti-Tamper solution as hard to crack, not as uncrackable," Goebl said.

"So far only one piracy group has been able to bypass it. As always, we continue working to improve our solution to create security updates for upcoming Anti-Tamper versions. We will do the same with the learning from this bypass.

"It's correct that the title in question was cracked some days after release. Given the fact that every unprotected title is cracked on the day of release – as well as every update of games – our solution made a difference for this title."

Upcoming games that feature Denuvo include South Park: The Fractured But Whole, Assassin's Creed Origins, and Sonic Forces.
