Even though Apple devotes a lot of resources towards bolstering iPhone security, every so often a bizarre bug emerges out of nowhere. The most recent example was unearthed by security researcher Carl Schou a few weeks ago. Posting on Twitter, Schou relayed how something funky happened to his iPhone when he connected to a WiFi network named “%p%s%s%s%s%n”. Upon doing so, the WiFi on his iPhone stopped working and couldn’t be restored.
Beyond WiFi connectivity issues, Schou noticed that other network-oriented activities like AirDrop stopped working as well.
