A wireless network naming bug has been discovered in Apple’s iOS operating system that effectively disables an iPhone’s ability to connect to a Wi-Fi network.
The issue was spotted by security researcher Carl Schou, who found that the phone’s Wi-Fi functionality gets permanently disabled after joining a Wi-Fi network with the unusual name “%p%s%s%s%s%n” even after rebooting the phone or changing the network’s name (i.e., service set identifier or SSID).
