It has come to our attention that from 6th May to today (12th May) the AppImage and Ubuntu zip assets of Cemu 2.6 on our github were compromised by a pro-Russian threat actor.
If you are a Windows or MacOS user you are not affected. If you are a flatpak user you are also not affected.

• Technical discovery Post by those who discovered it
• Cemu GitHub issue ticket

This means that downstream projects like EmuDeck, which downloads and installs Cemu directly from GitHub Releases was also affected.
