Living in this technology age, many of us have a fear of not being able to connect – not being able to reach people, keep up with social media, stream media, finish a deadline on time, etc. A new iPhone Wi-Fi bug has been discovered that makes any iPhone it comes near unable to connect to Wi-Fi. This new bug seems worse than a similar bug that was just discovered a few weeks ago.
New iPhone Wi-Fi Bug Discovered
Security researcher Carl Schou discovered the new iPhone Wi-Fi bug and reported it on Twitter.
He wrote on July 4, “You can permanently disable any iOS device’s Wi-Fi by hosting a public Wi-Fi named ‘secretclub%power.’ Resetting network settings is not guaranteed to restore functionality #infosec #0day.”
Schou came back later in the day and responded to his own tweet to say, “Seriously, I still don’t have Wi-Fi.”
While it seems a hard factory reset may fix the iPhone Wi-Fi bug, no one has come forward yet to say they tried it and that it worked. It seems to be such a dangerous issue that no one wants to attempt getting the bug to try the reset as a possible solution.
Connection to Earlier iPhone Wi-Fi Bug
On June 18, Schou reported a similar bug. He tweeted, “After joining any personal Wi-Fi with the SSID ‘%p%s%s%s%s%n,’ my iPhone permanently disabled it’s [sic] Wi-Fi functionality. Neither rebooting nor changing SSID fixes it. :~)”
A major difference between the two iPhone Wi-Fi bugs is that the earlier one is fixable by resetting the network settings. Another major difference is that the earlier bug relied on a user attempting to connect to the faulty network. The new bug, however, can be triggered by an iPhone simply coming within a certain range of a public Wi-Fi hotspot using that name.
It’s assumed that the two iPhone Wi-Fi bugs are connected because they both make use of a coding error within iOS. To avoid these two bugs and perhaps others of their ilk, you can avoid using networks that start with “%s,” “%p,” and “%n.”
You can be safer by avoiding networks that use percent signs in the title. To be even safer, avoid all unknown networks until a security update is released that will fix it.
