Planting false evidence is getting a new twist here. The attacker doesn't even have to make a report! The victim's computer does it for him. Disk encryption malware may have new successor. Effective and scalable extortion as a service.
- Kaytaro 5y agoThis is a great point. You don't even need to unlock an iPhone to take a picture. So in theory anyone with access to your phone for a few seconds could incriminate you with little effort.
- selsta 5y agoThis is already possible today with things like iCloud Photos, Google Photos, OneDrive etc.

- fossuser 5y agoThis is not true. The check is only against known CSAM hashes.
- noisem4ker 5y agoJust photograph a known bad picture.
- fossuser 5y agoThen that's a different photo and will have a different hash.
- Simucal 5y agoThese aren’t cryptographic hashes. They are perceptual hashes and a picture of a picture could absolutely end up with the same phash value.
- skavi 5y agois there really no fuzziness to it? If not, can’t this be defeated by simply reencoding the image?
- fossuser 5y agoI think it has gotten more sophisticated to detect cropped images and small changes now: https://inhope.org/EN/articles/what-is-image-hashing https://inhope.org/EN/articles/what-is-image-hashing The example is somewhat contrived. If a 'friend' takes your phone and has access to it and then uses it to take images of CSAM similar enough to the original image that it triggers the hash match and does this enough times to go over Apple's threshold to flag the account after these images are uploaded to icloud without the original phone owner noticing then yes it might cause a match. At that point the match is probably a good thing (and not really a false positive anyway) - since it may lead back to the friend (that has the illegal material).
- zbobet2012 5y agoOr you know, anyone who wants to plant material on a device and has physical access. Say a disgruntled employee before leaving, or ex, or criminal or... Or anyone who can just text you since imessage backs up to icloud automatically...
- jeromegv 5y agoWhile iMessage backups to iCloud, this measure is only for photos stored in the iCloud Photo Library. So sending a text with the photo is not enough.
