Researchers at the security firm MDSec have demostrated a way to bypass the iPhone's lockscreen using just a few hundred dollars in equipment. The iPhone lockscreen security bricks the phone after 10 incorrect guesses, but the researchers have found a way to power off the phone before it registers an incorrect guess. This allows attackers to cycle through all 10,000 possible passcodes without locking the phone, effectively bypassing the iPhone's first line of security.
