Because people don’t every patch their BIOSes, it is extremely likely that the vast majority of systems in the wild are vulnerable to at least one known exploit. We made public the details of the new SMM “Incursion” vulnerabilities (CERT VU# 631788, reported Oct 29th), that can be found automatically from SMM dumps. We showed the “LightEater” SMM implant stealing GPG keys/passwords/decrypted messages from Tails on an MSI system. We also showed how an unskilled attacker can infect a BIOS with an off-the-shelf Dediprog programmer, by just pressing the start button.
