Am I misremembering to think Genshin Impact was a cause of one of these major security disasters?

It wasn’t even people who installed Genshin that were victims - it was like, Microsoft signed a driver made by Mihoyo to scan for cheat apps. But mihoyo, being a game company with a rapid release cycle and imperfect security, had a vulnerability in the driver. So, malware authors could include that driver in their packages to elevate access on Windows installs even when no one had any idea what a Genshin is.

Not quite the same thing as Crowdstrike I guess though.
