Security risk
In theory, this bug could be a security risk. This is because malicious hackers can set up WiFi hotspots to allow people’s iPhones to connect without a password and destroy the device (albeit temporarily). This bug couldn’t be reproduced on Android, so it seems to be limited to Apple’s iOS operating system. Security experts believe that input analysis problems are probably the cause. Simply put, this means that the% character can confuse iOS with programming commands and variables.

“IOS is very intelligent, but the”% “character can confuse the operating system and mislead you into thinking it’s an alter ego from another language,” said Jake Moore, ESET’s cybersecurity specialist. Stated. “Fortunately, this bug isn’t permanent, but because it has a demonic mind, a malicious attacker can exploit the person who clicked it to exploit the situation. . “

I asked Apple for comment, but I’ll update this article when the iPhone maker responds. Fix
It’s easy to fix.>>>Just go to and reset your network settings.

Also, always keep in mind that when using your iPhone, you will connect to a random WiFi hotspot. “Needless to say, users need to be aware of unknown WiFi connections,” Moore says. “Threat attackers have long used rouge hotspots to catch prey, as they remain a quick and easy attack vector for unsuspecting victims.” In general, you should avoid unknown hotspots to keep your iPhone as safe as possible. For example, if you need to use WiFi in a cafe or hotel, we recommend using a VPN. However, for optimal security, we recommend that you always use a cellular network while you are out (that is, 4G or 5G).
