Researchers Build Covert Acoustical Mesh Networks In Air 107

An anonymous reader writes "Researchers at Fraunhofer FKIE, Germany have presented a paper on covert acoustical communications between laptop computers. In their paper 'On Covert Acoustical Mesh Networks in Air', they describe how acoustical communication can be used to secretly bridge air gaps between computers and connect computers and networks that are thought to be completely isolated from each other. By using ad-hoc routing protocols, they are able to build up a complete mesh network of infected computers that leaks data over multiple hops. A multi-hop acoustical keylogger is also presented where keystrokes are forwarded to an attacker over multiple hops between different office rooms. The fundamental part of the communication system is a piece of software that has originally been developed for acoustic underwater communications. The researchers also provide different countermeasures against malicious participation in a covert acoustical network. The limitations of air gaps have been discussed recently in the context of a highly advanced malware, although reports on this so-called badBIOS malware could not yet be confirmed."

Glad the populace on there will enjoy HTTPS as I have been explicitly been using for years now. I never wanted my pesky network admins sitting on the wire and watching what I post when I am at work ... errrrr on break ... errr I mean ...

Sure we aren't talking about Alabama here. ASU has some of the hottest college chicks in the US. If you got out of the basement now and then you might have known that. Albeit that has nothing to do with this topic so why Phoenix you ask ... because it's easier to melt silicon there? DUH! /ducks

Agreed but I don't think all field agents are a fail. At my previous job, which was actually raided by the FBI, they seized servers took what I assume they were looking for, deleted the video captured during the actual seizure which was found by IT when they returned them weeks later. After this was when I began my search for a job at a company that wasn't under scrutiny of a federal agency.
