Scientist-developed malware covertly jumps air gaps using inaudible sound

Quote:
Computer scientists have developed a malware prototype that uses inaudible audio signals to communicate, a capability that allows the malware to covertly transmit keystrokes and other sensitive data even when infected machines have no network connection.

The proof-of-concept software—or malicious trojans that adopt the same high-frequency communication methods—could prove especially adept in penetrating highly sensitive environments that routinely place an "air gap" between computers and the outside world. Using nothing more than the built-in microphones and speakers of standard computers, the researchers were able to transmit passwords and other small amounts of data from distances of almost 65 feet. The software can transfer data at much greater distances by employing an acoustical mesh network made up of attacker-controlled devices that repeat the audio signals.

Was that a fart I just heard, or malware in the room?

Would that be called malicious malodorous malware?

Hahaha. Quite ironic given mal is latin for "bad"

I'm impressed, Colin. I thought the only foreign language you spoke was Australian.

I was always had the understanding that high security domains/network like DoD, NASA, PlayBoy Club, ect where already isolated from any signals. Sound, RF and all the rest. All cable runs shielded and grounded and the like. A/C power isolated and filterer so nothing gets in or out that way either. It's called a secure I.T. room and/or building.
Lets not forget VLF and ULF (Very Low Frequency) (Ultra Low Frequency). They travel very far and trough most everything. I don't believe a computer can transmit such signals because of the power needed but might be able to receive them allowing a bug to be installed into a high risk secure system.

Sounds interesting, but...

Wouldn't the computer need a microphone that can hear "inaudible audio signals"? The average microphone that you can get is around 40Hz - 18kHz at best, pretty much the wave length you can hear; if you get one that 20Hz - 20kHz, it can process sound waves that average adult cannot even hear. And don't tell me that the speaker, that pretty much has the same audio signal as the average microphone, can reproduce inaudible signals.

It seems to me that this article is just feeding the paranoia....

Just a thought.
Microphones and speakers are designed to work the best within the human hearing range but I don't think that means it can't be used to also work out side that hearing range at the same time.
Paranoia is one of the layers of security.

The article mentions that the communication methods were developed for underwater communications. Such communications often use spread spectrum techniques that can deal with ambient noise. And I could be wrong, but I don't think that you will be able to hear short duration pulses :-)

Here is an article about info via "inaudible" audio from 2008...

...but it was not attempting to be totally stealthy.
