Swedish hacker and penetration tester Ulf Frisk has devised a $300 device, dubbed PCILeech, that could be exploited by an attacker to gain full control of a Mac or MacBook. The device is able to steal the password from virtually any Mac laptop while it is sleeping or even locked. The process is very fast, in just 30 seconds hackers can unlock any Mac computer and even decrypt the files on its hard drive. The security expert devised a technique that leverage on two designing flaws he discovered in Apples FileVault2 full-disk encryption software.”]
