New iOS exploit named ‘checkm8” discovered

An iOS researcher with the Twitter handle @asi0mX has announced the release of a new iOS exploit named checkm8 that claims to have serious consequences for iPhone and iPad hardware, as well as Apple Watches.

According to the tweet, this exploit is a “permanent unpatchable bootrom exploit,” capable of affecting devices from iPhone 4S up to the iPhone X and various iPad, Apple Watch and Apple TV models. The devices that are vulnerable to checkm8 are purportedly the following: iPhones from the 4s up to the iPhone X; iPads from the 2 up to the 7th generation; iPad mini 2 and 3; iPad Air 1st and 2nd generation; iPad Pro 10.5-inch and 12.9-inch 2nd generation; Apple Watch Series 1, Series 2, and Series 3; Apple TV third generation and 4k; iPod Touch fifth generation to seventh generation. Malwarebytes Labs has posted a blog about this and says the implications of this exploit are serious. 

“Apple will not be able to patch this in software updates, and only purchasing a whole new, updated device would fix the problem,” says Malwarebyte Labs. “Additionally, though checkm8 is not a remote exploit (meaning that a hacker would have to be physically holding your device to hack it), devices do not need to be unlocked to use this exploit.”
