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).

The bug could have serious implications in that bad actors could exploit the issue to plant fraudulent Wi-Fi hotspots with the name in question to break the device’s wireless networking features.
