Earlier this year, Apple patched one of the most breathtaking iPhone vulnerabilities ever: a memory corruption bug in the iOS kernel that gave attackers remote access to the entire device—over Wi-Fi, with no user interaction required at all. Oh, and exploits were wormable—meaning radio-proximity exploits could spread from one near-by device to another, once again, with no user interaction needed.
This Wi-Fi packet of death exploit was devised by Ian Beer, a researcher at Project Zero, Google’s vulnerability research arm. In a 30,000-word post published on Tuesday afternoon, Beer described the vulnerability and the proof-of-concept exploit he spent six months developing single handedly. Almost immediately, fellow security researchers took notice.
