AirDrop and Quick Share Flaws Allow Nearby Service Crashes

Security researchers have identified multiple vulnerabilities in the wireless file-sharing features used by billions of Apple and Android devices, allowing a nearby attacker to temporarily disable key services. The findings, published on June 30, 2026, detail six flaws across Apple's AirDrop and the Google and Samsung Quick Share systems.

Researchers Arash Ale Ebrahim and Nils Ole Tippenhauer from the CISPA Helmholtz Center for Information Security conducted the analysis, reverse-engineering the application-layer protocols. They found that an attacker within approximately 10 to 30 meters needs only a Wi-Fi-equipped laptop, with no prior pairing or shared network required. The attack primarily disrupts service availability and does not allow the theft of files or execution of arbitrary code.

On Apple devices, three vulnerabilities were discovered, all causing a crash in a background service called "sharingd." This service also powers AirPlay, Handoff, Universal Clipboard, Continuity Camera, and NameDrop, meaning a single crash can disable this entire suite of features simultaneously. The simplest method involves sending a malformed network request to a device configured to...
