> CamScanner was actually a legitimate app, with no malicious intensions whatsoever, for quite some time. It used ads for monetization and even allowed in-app purchases. However, at some point, that changed, and recent versions of the app shipped with an advertising library containing a malicious module.

IMO, this is more a legal matter than a technical one.

Google needs to sue this company, not engage in a whack-a-mole game with their AI algorithm and useless scanner.
