Be thorough about giving your WiFi network an unusual title — it may possibly produce major complications for any iPhone users in the home. BleepingComputer and AppleInsider say that security researcher Carl Shou has found out a naming bug that ‘breaks’ WiFi on iOS products. Give your network an SSID like “%p%s%s%s%s%n” and your iPhone will eliminate WiFi functionality. You can get it back again by resetting your network configurations (Configurations > Normal > Reset > Reset Network Settings), but which is evidently a ache if you just wished to avoid making use of mobile data.
The trigger is just not very clear at this issue, but BleepingComputer speculated that it could possibly be a string formatting flaw. Only place, iOS could confuse the % entries with programming commands and variables. Schou famous that he on a regular basis takes advantage of names like this to mess with “improperly produced equipment.” He tested the bug with iOS 14.4.2, but it was even now a trouble as of iOS 14.6.
We’ve questioned Apple for remark.
Character-similar bugs aren’t unheard of. A 2018 bug in iOS and macOS crashed apps making use of a single symbol. WiFi issues are unusual, having said that, and this glitch would make it somewhat effortless for pranksters to (quickly) wreck your phone making use of public hotspots. Although it was presently a good strategy to prevent connecting to odd hotspots, you may have a specially very good motive to resist that temptation when this bug exists.
