They discover in the iPhone a ‘bug’ that blocks the WiFi connection when referring to a network with a strange name | #ios | #apple | #iossecurity

A computer expert recently identified an iPhone ‘bug’ that can block the WiFi connection and disable it permanently, without restarting the device to solve the problem.

First reported by Bleeping Computer, the vulnerability was discovered by engineer Carl Schou, who began to have problems accessing a WiFi network called% p% s% s% s% s% on your iPhone.

When trying to connect to it, he realized that his cell phone was prevented from accessing any other network. He tried to fix it by changing the signal name (SSID) and restarting his ‘smartphone’, but none of the options helped.

“After joining a personal WiFi with the SSID ‘% p% s% s% s% s% n’, my iPhone permanently disabled its WiFi functionality. Neither restarting nor changing the SSID fixes it,” Schou detailed in a tweet.

The engineer explained that the problem was presented to him on an iPhone XS, running iOS 14.4.2. But it was not the only case: Bleeping Computer tested the ‘bug’ on an iPhone with the latest version of iOS, 14.6, and the problem was still there: the WiFi was blocked when connecting to that wireless network with a strange name.

In theory, this bug could be a security risk, as it would allow hackers install WiFi hotspots to make other people’s iPhones connect to them without the need for a password, thereby ‘hacking’ their devices (even temporarily).

The ‘bug’ could not be replicated on Android, so it appears to be isolated on Apple’s iOS operating system. Security experts believe that an input scan problem could be the cause. In detail, the ‘%’ character could confuse the iOS in terms of programming commands and variables.

Fortunately, the solution is simple: you just have to reset the network settings, just go to Settings> General> Reset> Reset network settings.

Bottom line: When using your iPhone, you should avoid unknown access points to keep your device as secure as possible. And if you have to use WiFi in cafes or hotels, for example, it is advisable to use a VPN.
