This can also be used to make Apple's system useless, no? If enough (millions?) of people were to, say, go to a web site and save generated gray-blobs to their phones, it would create enough false-positives to kill this system, right? Maybe game it and have everyone convert their various profile pics to these images.

No, because Apple will simply start killing Apple IDs and blocking hardware by serial number for abusive behavior towards Apple when y’all do that, and that’s a very expensive problem to overcome. “You tried to exploit our production systems and we’re ending our customer relationship with you over it” is a classic Apple move and no one outside of the Hackintosh community realizes that their devices include crypto-signed attestations of their serial number during Apple service sign-ins.

And how would anyone know that those gray blobs match child porn?

  Exactly, that’s the scary abuse scenario where people could send a whole load of this stuff to e.g a political enemy.

    What? Why do you think gray blobs would hurt anyone?

      No one is going to send gray blobs, they will be finding legal porn (like pussy close ups, tongue pics, whatever) and then disturbing it to trigger a CSAM hit. The low res derivative will match, perhaps even closely, because pussy closeups look similar to an apple employee when its grayscale 64 by 64 pixels (remember: it's illegal for Apple to transmit CSAM, so it must be so visually degraded to the point where it's arguably not visual). The victim will get raided, be considered a paedophile by their workplace, media, and family, and perhaps even go into jail. The attacker in this case can be users of Pegasus unhappy with a journalist.

        And disturbing it enough to match CSAM would make it obvious it’s been tampered with. And how would the attacker obtain the CSAM hashes they’d need to match?
