“thunderstrike 2” Rootkit Uses Thunderbolt Accessories To Infect Mac Firmware

Earlier this year, security engineer Trammell Hudson developed and showed off a proof-of-concept firmware called Thunderstrike. The malware could hitch a ride on Thunderbolt-connected accessories that used Option ROMs and infect any Mac it was connected to at boot. The infected Mac could then pass the malware to other accessories, which could infect other computers. Apple (mostly) patched this exploit in OS X version 10.10.2 back in January, but Wired reports that Hudson and LegbaCore security researcher Xeno Kovah have developed a sequel. Dubbed "Thunderstrike 2," the new proof-of-concept attack still spreads primarily through infected Thunderbolt accessories.
