An in-depth report from Ars Technica highlights a rootkit (a piece of software that typically hides itself deep in an operating systems Kernel or a computers BIOS) that is capable of communicating with nearby computers using a systems speaker and microphone. Dubbed badBIOS, the malware has been plaguing renowned security researcher Dragos Ruius computers for three years. Similar in nature to many other rootkits, badBIOS does its best to prevent users from erasing it, including removing the computers ability to boot from a physical disc. Ruiu believes badBIOS represents the first visible stages of a larger attack that can affect Windows, OSX, Linux, and BSD systems.
