Seriously, now I want to buy a camera, smash the chip, and crack their firmware so it doesn't have the check. As far as I know there is no secureboot involved, so it should be trivial. This Is Just Inexplicably Dumb.https://twitter.com/marcan42/status/1088472549715918848 …

So it took you all of, what, 12h to pwn their shitty drm? Is the stuff in IDA there a fw blob from the chip? What did it take to extract it?

More like 1h, there was sleep in between. I went to their GitHub, downloaded the blob, threw it into IDA, FindCrypt immediately found the SHA256 table, then I hit 'x' a few times.
