> Who needs SWATing when you can send a CP pic (either real or with hash collision as per the thread few days ago) from a virtual overseas number/service and get FBI van to show up as well?

You are talking like collisions are trivial to make. I bet they have had a deep conversations in this area. At first, you would need a real hash to even try (which are hidden). Secondly, to get real material it means that it must be in their database to trigger anything. This tells a lot from sender already, and is worth to tell for police. It is quite easy to prove that someone just send it to you. And one photo is not triggering anything. Besides, sender must know that those photos must go automatically into the cloud to mean anything.

> What about injecting code into a public website to download same pic into local browser cache without user’s knowledge?

At least US legistlation is precise that user must willingly obtain/download CSAM material, and it must be proved. So this is not harmful for the user in the end.

A lot of speculation, but does not really lead for coencequences. Almost every system can be tried to be abused, but does it really mean something, is different story.

Step 1: Get copies of pictures of targets kid in bath from phone/SNS

Step 2: Manipulate pictures so that hash collides with CSAM

Step 3: Get pictures back on targets phone so they get scanned.

I don't have the skills or understanding of how the hashes are created but would this be possible?

How are the hashes hidden? It looks like they are shared: https://www.thorn.org/reporting-child-sexual-abuse-content-s...

These hashes are not generated by Apple and are not valid. (Must be generated by their new system) They are probably very strictly guarded.

They will be stored on every iOS from 15 version, somehow securely. This must limit the support of older iPhones.

Except that a trial, even with an innocent verdict will SUCK and have terrible news stories about you and poison any google search for you with CSAM stories
