If you have an iPhone, beware of a strange wifi network with the name “%p%s%s%s%s%n.” This name causes a burdensome bug. Do not connect to this network unless you want your phone’s wifi functionality to break.
The bug was found by security researcher Carl Schou, who shared the problem on Twitter. Schou explained that after he joined network “%p%s%s%s%s%n”, his iPhone permanently disabled its wifi functionality. According to 9to5Mac, the bug also affects iPads, as well as services like AirDrop. The devices are unable to connect to wifi networks even after rebooting or changing the hotspot’s SSID.
