It has been discovered that Apple acquired the two security researchers behind LegbaCore, Corey Kallenberg, and Xeno Kovah -- the developers of the firmware worm for Macs known as Thunderstrike 2. The hiring was revealed by fellow security researcher Trammell Hudson at a security conference in December, with Apple having brought the pair on board the previous month. LegbaCore had developed a method to infect Macs with a difficult-to-remove firmware hack that could be delivered via altered Thunderbolt connectors.
