Bug in iOS can break iPhone Wi-Fi using rogue hotspot name

San Francisco: A bug has been discovered in iOS that can disable an iPhone’s ability to connect to Wi-Fi hotspots if it attempts to initially connect to a hotspot with a specific name that breaks the function.

Security researcher Carl Schou gave a personal Wi-Fi hotspot a name comprising special characters — “%p%s%s%s%s%n”.

On trying to connect to the hotspot, Schou discovered the iPhone simply couldn’t connect to it at all, and later discovered that it disabled Wi-Fi connectivity completely on the device, AppleInsider reported.
