CODEX (also known as CDX) – is a warez group founded at the end of February 2014. They are known for releasing copies of games which use Steam licensing and also for emulating Ubisoft’s Uplay digital rights management protection. They were accused by the warez group SKIDROW of stealing their code to crack Trials Fusion, something CODEX denied, [self-published source] stating that they had written their own
code for the DRM emulation. From 2016 to 2020 they have been one of the most active warez groups releasing commercial computer games with over 3700 releases in less than 6 years, compared to older groups like SKIDROW having fewer than 2500 over more than a decade of activity. In late 2017 CODEX gained notoriety by becoming the third scene group (and fifth overall entity) to crack Denuvo DRM when they released a cracked version of Middle-earth: Shadow of War on its release date. CODEX collaborated with STEAMPUNKS on at least one game which used Denuvo DRM, South Park: The Fractured But Whole, which they released under the name “CODEPUNKS“. In February 2018 CODEX began releasing cracked copies of games from the Microsoft Windows Store.
In mid-2018 CODEX began releasing cracked copies of games featuring the latest versions of Denuvo DRM, including updated versions of Assassin’s Creed Origins and Far Cry 5, both of which used Uplay licensing DRM and contained additional anti-modification and anti-debugging code through the use of VMProtect. On February 1, 2019, CODEX published a cracked copy of Resident Evil 2, which used Denuvo DRM, 7 days after the worldwide commercial release of the game. In late June 2019, CODEX released two cracked copies of games which utilized Denuvo DRM, Shadow of the Tomb Raider and a cracked updated version of Metal Gear Solid V: The Phantom Pain. These cracks were previously released by an independent cracker on the web, attributed to the group “EMPRESS”. Later, a cracker who self-identified as C0000005 began releasing cracks under the name EMPRESS as well, suggesting that they are one and the same and that C0000005 had access to source code for CODEX’s cracks. On June 27, 2019 CODEX released a crack for Star Wars Battlefront 2, about 527 days after its commercial release. On October 29, 2019 they published a cracked copy of Borderlands 3, another game distributed with Denuvo DRM, 46 days after release.
