The Indie Stone has identified a security issue involving 14 mods on the Steam Workshop for Project Zomboid, which contain heavily obfuscated code linked to the creation of malicious files outside the game's directory. Reports from players indicated that one mod was generating harmful code, prompting an investigation that confirmed the presence of the exploit across multiple mods uploaded by the same user. The affected mods had between 500 and 2,200 installations, and the user has been banned while the mods have been removed from the Steam Workshop. The exploit specifically affects Build 42 branches of Project Zomboid, with players using Build 41 being unaffected. The Indie Stone advises players who downloaded these mods to take security precautions beyond simply uninstalling them. The affected mods include various soundtracks, such as Risk of Rain 2 OST, NieR: Automata OST, and others, each with specific Workshop and Mod IDs.
