Swedish hacker and penetration tester has developed a new device that can steal the password from virtually any Mac laptop while it is sleeping or even locked in just 30 seconds. The $300 device exploits two designing flaws in Apple’s FileVault2 full-disk encryption software. Attack only works if an attacker has physical access to a target Mac or MacBook, but all it takes is 30 seconds to carry out successfully. Apple desktop users must update their devices to the latest version of its operating system to be safe.
