A newly announced iOS exploit could lead to a permanent, unblockable jailbreak on hundreds of millions of iPhones, according to researcher axi0mX who discovered it. Dubbed “checkm8,” the exploit is a bootrom vulnerability that could give hackers deep access to iOS devices on a level that Apple would be unable to block or patch out with a future software update. That would make it one of the biggest developments in the iPhone hacking community in years.
