It is unlikely that computer viruses can stay completely undetectable indefinitely as such attacks are already known to the security industry and efforts are ongoing to detect and eradicate even deeply embedded hardware-based backdoor malware. In time, the virus will also be eradicated thus debunking the notion of an invulnerable virus, say observers.
The idea for such a virus came in August when Jonathan Brossard, CEO and security research engineer at Toucan System, demonstrated the
"Rakshasa" virus which is a deeply embedded backdoor installed on the BIOS chip on a PC's motherboard or other hardware components such as network cards.
