If you have not already, make sure to update your iPhone or iPad Touch to iOS 10.3.3 released by Apple last night. The change log for the update was pretty sparse and indicated that the release primarily contained security patches. Among the exploits that Apple has fixed in this release, one of them was particularly critical and allowed hackers to take complete control of your device.
The exploit allowed hackers to execute arbitrary code on the Wi-Fi chip of your iPhone and iPod Touch, take control of it and then ultimately crash it. Initially, it was believed that the exploit only allowed hackers access to the Wi-Fi chip. However, as Nitay Artenstein of Exodus Intelligence discovered, the exploit also allowed hackers to run arbitrary code on the main application processor as well.
The exploit, known was Broadpwn exploit, was also recently patched by Google with its July security update for compatible Pixel and Nexus devices. The exploit scored 9.8 out of 10 in terms of severity in the US National Institute of Standards and Technology.
The vulnerability stemmed from the Broadcom Wi-Fi chip that Apple uses inside its iPhone and iPad.
The vulnerability affects iPhones starting from the iPhone 5 to the iPhone 7, with the fourth-generation iPad and above also being affected. So, if you have not already, make sure to update your iPhone, iPad, or iPod Touch to iOS 10.3.3 right away to patch this exploit.
