badBIOS: airgap-jumping malware that may use ultrasonic networking to communicate

Security researcher Dragos Ruiu has been painstakingly untangling a weird, scary piece of malicious software that compromises the BIOS of the computers it attacks, allowing it to infect machines with different operating systems. He's dubbed it "badBIOS" and has seen it infect machines that aren't connected to the Internet. It appears that its initial vector may be a USB exploit, spreading by memory stick, but after that, it appears that it continues to communicate with other infected machines by ultrasonic networking through its hosts' mics and speakers (!). On Ars Technica, Dan Goodin has a deep dive into the strange, freaky world of badBIOS.
