The world's most secure consumer OS is bitten by a garden-variety programming bug.

By connecting to a Wi-Fi network that uses the SSID “%p%s%s%s%s%n” (quotation marks not included), iPhones and iPads lose the ability to join that network or any other networks going forward, reverse-]engineer Carl Schou reported on Twitter

Schou, who is the owner of hacking resource Secret Club, initially saw no easy way to restore Wi-Fi capabilities. Eventually, he found that users could reset network functionality by opening Settings > General > Reset > Reset Network Settings.

When I first saw this e-mail title, I thought it might be about facetious WiFi names, like "FBI Van 3" or (ours) "IRS Surveillance Net".

I did too. But a coworker was hit with this in DFW a couple of weeks ago. Definitely real.
