Three years ago, security consultant Dragos Ruiu was in his lab when he noticed something highly unusual: his MacBook Air, on which he had just installed a fresh copy of OS X, spontaneously updated the firmware that helps it boot. Stranger still, when Ruiu then tried to boot the machine off a CD ROM, it refused. He also found that the machine could delete data and undo configuration changes with no prompting. He didn't know it then, but that odd firmware update would become a high-stakes malware mystery that would consume most of his waking hours.

In the following months, Ruiu observed more odd phenomena that seemed straight out of a science-fiction thriller. A computer running the Open BSD operating system also began to modify its settings and delete its data without explanation or prompting. His network transmitted data specific to the Internet's next-generation IPv6 networking protocol, even from computers that were supposed to have IPv6 completely disabled. Strangest of all was the ability of infected machines to transmit small amounts of network data with other infected machines even when their power cords and Ethernet cables were unplugged and their Wi-Fi and Bluetooth cards were removed. Further investigation soon showed that the list of affected operating systems also included multiple variants of Windows and Linux.

"We were like, 'Okay, we're totally owned,'" Ruiu told Ars. "'We have to erase all our systems and start from scratch,' which we did. It was a very painful exercise. I've been suspicious of stuff around here ever since."

In the intervening three years, Ruiu said, the infections have persisted, almost like a strain of bacteria that's able to survive extreme antibiotic therapies. Within hours or weeks of wiping an infected computer clean, the odd behavior would return. The most visible sign of contamination is a machine's inability to boot off a CD, but other, more subtle behaviors can be observed when using tools such as Process Monitor, which is designed for troubleshooting and forensic investigations.

Another intriguing characteristic: in addition to jumping "airgaps" designed to isolate infected or sensitive machines from all other networked computers, the malware seems to have self-healing capabilities.

Ruiu posited another theory that sounds like something from the screenplay of a post-apocalyptic movie: "badBIOS," as Ruiu dubbed the malware, has the ability to use high-frequency transmissions passed between computer speakers and microphones to bridge airgaps.

Sounds like some mad creepypasta for PC geeks.

I love the one where the guy hears a scratching noise from inside his PC case and when he opens it there's just a hook.

Ooh gives me goosebumps just thinking about it!

And then Dragos was malware.
