Sick Beats: Using Music And Smartphone To Attack A Biosafety Room

Imagine a movie featuring a scene set in a top-secret bioweapons research lab. The villain, clad in a bunny suit, strides into the inner sanctum of the facility — one of the biosafety rooms where only the most infectious and deadliest microorganisms are handled. Tension mounts as he pulls out his phone; surely he’ll use it to affect some dramatic hack, or perhaps set off an explosive device. Instead, he calls up his playlist and… plays a song? What kind of villain is this?

As it turns out, perhaps one who has read a new paper on the potential for hacking biosafety rooms using music. The work was done by University of California Irvine researchers [Anomadarshi Barua], [Yonatan Gizachew Achamyeleh], and [Mohammad Abdullah Al Faruque], and focuses on the negative pressure rooms found in all sorts of facilities, but are of particular concern where they are used to prevent pathogens from escaping into the world at large.

Digispark Spoofs IR To Get Speakers Under Control

The Microlab 6C are a pretty nice pair of speakers, but [Michał Słomkowski] wasn’t too thrilled with the 8 watts they consume when on standby. The easy fix is to just unplug them when they aren’t in use, but unfortunately the digital controls on the front panel mean he’s got to turn them on, select the correct input, and turn the volume up to the appropriate level every time they’re plugged back in. Surely there must be a better way.

His solution was to use a Digispark to fire off the appropriate IR remote codes so they’d automatically be put back into a usable configuration. But rather than putting an IR LED on one of the GPIO pins, he simply spliced it into the wire leading back from the speaker’s IR receiver. All his code needs to do is generate the appropriate pulses on the line, and the speaker’s electronics think its a signal coming in from the remote.
