An iOS researcher (known as @asi0mX on Twitter) has announced the release of a new iOS exploit named checkm8 that claims to have serious consequences for iPhone, iPad and Apple Watches.
According to the tweet, this exploit is a “permanent un-patchable 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.”

Most generations of iPhones and iPads are vulnerable: from iPhone 4S (A5 chip) to iPhone 8 and iPhone X (A11 chip). https://t.co/dQJtXb78sG
