Security researchers developed a new BIOS bootkit that exploit recently discovered vulnerabilities. The experts will present their study to the CanSecWest conference in Vancouver. The implant is injected into System Management Mode that is a computer operating mode in which all normal execution, including the operating system, is suspended and special software, including firmware, is executed with high privileges. The researchers highlighted that also secure distro like Tails could be targeted by the implant, the implant could be used to steal sensitive data and also the secret PGP key used by the popular OS.”]
