Thunderspy

Thunderspy is a security vulnerability that affects Thunderbolt ports on certain computers, allowing unauthorized access to data without the need for physical access to the device. Discovered in 2020 by security researcher Jannes Arnéra, the vulnerability takes advantage of how Thunderbolt technology handles direct memory access (DMA). When exploited, Thunderspy can permit an attacker to bypass operating system security measures and gain unauthorized access to files and sensitive information stored on the device.
