alphadogg writes: Security researcher Jonathan Brossard has created a proof-of-concept hardware backdoor called Rakshasa that replaces a computer's BIOS and can compromise the operating system at boot time without leaving traces on the hard drive. Brossard, who is CEO and security research engineer at French security company Toucan System, demonstrated how the malware works at the Defcon hacker conference over the weekend. Rakshasa, named after a demon from the Hindu mythology, is not the first malware to target the BIOS — the low-level motherboard firmware that initializes other hardware components. However, it differentiates itself from similar threats by using new tricks to achieve persistency and evade detection.
