APPLE WILL SCAN SHARED ICLOUD LINKS FOR HARMFUL CONTENT, BUT WON'T EXPLAIN WHAT COUNTS AS HARMFUL

Summary from the TLDR InfoSec newsletter

Apple will check photos and files shared via iCloud's “Anyone with the Link” setting for harmful content on iOS, iPadOS, and macOS 27.3. Publicly shared items lose end-to-end encryption, even with Advanced Data Protection enabled. Apple can remove files, block accounts, prevent re-registration, and contact law enforcement. It has not defined “harmful,” explained the screening method, said whether people review flags, or confirmed whether existing public links are covered.
