A new attack enables bad actors to steal data from Windows or Linux devices equipped with Thunderbolt ports if they can get their hands on the device for just five minutes. The attack, called Thunderspy, specifically targets Thunderbolt technology, which is a hardware interface developed by Intel (in collaboration with Apple) that allows users to consolidate data transfer, charging and video peripherals into a single connector. Attackers could then bypass security measures and access data even if the target device is locked and its drive encrypted.
