The Cemu development team announced that specific Linux builds of their Wii U emulator, Cemu 2.6, were compromised with malware. This affects AppImage and ZIP downloads retrieved directly from the project's official GitHub repository between May 6 and May 12, 2026. Users who downloaded and executed these compromised builds during that week may have had malware added to their systems. The team stated they "discovered the Linux AppImage and ZIP of the Cemu 2.6 release available from their Github had been 'compromised' with malware" within the specified timeframe. Notably, the Cemu Flatpak package and installers for other operating systems were not affected by this security incident.
