iPhone could be hacked remotely using zero-day bug in Airdrop, now fixed

A bug in Apple iPhones and other iOS devices could let hackers take complete control of the device given that they were in the vicinity, according to Google Project Zero security researcher Ian Beer. Airdrop lets Apple users transfer pictures and files to other iOS devices while Sidecar lets them turn their iPad into a secondary screen. The exploit was found in iOS 12.4.7 and Apple in the security content document noted that "A remote attacker may be able to cause unexpected system termination or corrupt kernel memory." Instead, it should be: one person, working alone in their bedroom, was able to build a capability which would allow them to seriously compromise iPhone users they'd come into close contact with,” Beer wrote in his Project Zero article.
