More on my ongoing chase of #badBIOS malware. It’s been difficult to confirm this as I’m down to a precious few reference systems that are clean. I lost another one yesterday confirming that’s simply plugging in a USB device from an infected system into a clean one is sufficient to infect. This was on a BSD system, so this is definitely not a Windows issue.- and it’s a low level issue, I didn’t even mount the volume and it was infected. Could this be an overflow in the way bios ids the drive?

Beware of ads that use inaudible sound to link your phone, TV, tablet, and PC | Ars Technica

Privacy advocates are warning federal authorities of a new threat that uses inaudible, high-frequency sounds to surreptitiously track a person’s online behavior across a range of devices, including phones, TVs, tablets, and computers.

The ultrasonic pitches are embedded into TV commercials or are played when a user encounters an ad displayed in a computer browser. While the sound can’t be heard by the human ear, nearby tablets and smartphones can detect it. When they do, browser cookies can now pair a single user to multiple devices and keep track of what TV commercials the person sees, how long the person watches the ads, and whether the person acts on the ads by doing a Web search or buying a product.
