Two researchers found six flaws in Apple's AirDrop and Android's Quick Share, the wireless sharing apps. Attackers on the same network or within a ten to thirty meter radius can intercept the file transfer request before its made when transferred to everyone, and send a malformed data packet for the attackers denial-of-service attack. For Apple, once the data packet takes down sharingd, the background service that handles AirDrop, AirPlay, Handoff, Universal Clipboard, and more, are all also affected. This packet bypasses security checks and crashes the software, freezing the sharing app. Out of Apple's three flaws, one has been patched, and out of Android's three flaws, two are under investigation and one was paid a bounty. Since this attack only occurs if it's shared to everyone, it's suggested that the settings should be changed to "Contacts Only" or off, so that it's not exposed to the public.
