Three AirDrop vulnerabilities have been discovered by security researchers, affecting both iPhone and Mac, with similar ones found in Android’s Quick Share.
An attacker could easily exploit the vulnerabilities to cause AirDrop, AirPlay, Handoff, Universal Clipboard, and Continuity Camera to crash and remain unavailable for as long as the attack continues …
HelpNetSecurity reports that it is a simple attack to initiate.
A proximity attacker needs a laptop with Wi-Fi and a spot within range, often 10 to 30 meters. No pairing, contact exchange, or shared network is required. On Apple devices set to receive from “Everyone,” the early protocol phases respond before any user prompt appears.
The good news is that no data can be obtained. The bad news is that a number of related Apple services on both iPhone and Mac can be remotely disabled.
