Björn Ruytenbe, a Dutch security researcher at Eindhoven University of Technology, revealed details this week of a new attack he discovered that exploits a vulnerability in the common Intel Thunderbolt port found in millions of PCs around the world. The attack, called Thunderspy, takes less than 5 minutes to perform, but it must be executed in person, for the hacker needs physical access to the target laptop. This kind of attack is called by researchers an “evil maid attack.”
