Pierwszy na świecie bootkit dla Maców →

Dan Goodin:

Securing Macs against stealthy malware infections could get more complicated thanks to a new proof-of-concept exploit that allows attackers with brief physical access to covertly replace the firmware of most machines built since 2011.

Once installed, the bootkit—that is, malware that replaces the firmware that is normally used to boot Macs—can control the system from the very first instruction. That allows the malware to bypass firmware passwords, passwords users enter to decrypt hard drives and to preinstall backdoors in the operating system before it starts running. Because it’s independent of the operating system and hard drive, it will survive both reformatting and OS reinstallation. And since it replaces the digital signature Apple uses to ensure only authorized firmware runs on Macs, there are few viable ways to disinfect infected boot systems. The proof-of-concept is the first of its kind on the OS X platform. While there are no known instances of bootkits for OS X in the wild, there is currently no way to detect them, either.

Nie udostępniajcie swoich komputerów osobom, którym nie ufacie i nie zostawiajcie ich nigdzie bez nadzoru.
