That is a very good point 78RPM - I am just wondering what justified a full blown effort at developing malware when as they have stated, "However, the scientists have divulged several counter measures that can be put into place to nullify acoustical intrusions, with one being simply to shut off the PCs audio input/output devices. Another method is to install audio filters that are capable of blocking certain high frequency ranges that are used to transmit covert data."

It seems to me that developing countermeasures against known audio technology would not require creating malicious code to test it - audio sent at different frequencies could have provided the same stimulus.

I'm taking the Digi-Key Design News class this week on SCADA Security. The instructor Clint Bodungen states that by the time a vulnerability goes public, it has already been in circulation. Publicity is important because it lets the "good guys" know about possible attacks from the "bad guys."

I agree, Elizabeth. It puzzles me as to so much time, money, and energy being directed at developing something that seems to say - yes - this can be done. As with any malicious software - the nature of the beast must be known in order to institute countermeasures but was it really necessary to conduct all of that research and develop their own algorithm? Now hackers are aware of audio possibilities they may have not considered before.

Well this is fascinating technology but we don't really need another way for malware to be transmitted, do we? It's good to know people don't have to worry about this quite yet nor that much data can be transmitted this way. But who knows what can happen if a clever hacker gets ahold of it and messes with the code.
