Good to see a POC that shows how useless security-wise is the Play Integrity:
Android LPE using DRAM bitflip => https://bsky.app/profile/retr0.id/post/3mljtyauw322d
A requirement to get any security protection with the Play Integrity is that attackers can't bypass it on any device.
As soon as an attacker can bypass it, it is possible to distribute app clones (fake banking app) that proxy-pass the Integrity requests to a controlled device, defeating the Play Integrity.
On the other side, how many users are locked-out of critical services because of the Play Integrity? For legit users, any non-trivial workaround is a blocker.
Play Integrity is not about security, but about coercition, Google's tool to impose their conditions: eg. forcing OEM to preinstall their apps, some with privileges (Chrome, Youtube, Play Services, etc)
