Backdoored Cemu release linked to TanStack and Mistral supply chain campaign

A coordinated supply chain attack compromised the official GitHub release of Cemu, a Nintendo Wii U emulator, with a backdoor that reached approximately 20,000 Linux users. The same campaign affected npm and PyPI packages, including those associated with TanStack and Mistral.

Why it matters: Software developers and Linux users who downloaded Cemu from the official repository may have executed malicious code; practitioners should verify the integrity of recently installed packages across development ecosystems and check for indicators of compromise from this supply chain operation.
