Soundwave hacking!

In the future, computer hackers could steal sensitive data from people’s computers using nothing but soundwaves, experts have warned.
German computer scientists have proved the idea is possible by developing a new type of malware that can travel between machines using soundwaves that are inaudible to unsuspecting humans.
Using built-in microphones and speakers in laptops, the researchers managed to transmit passwords and small amounts of data between machines 65ft away from each other.
The terrifying feat was achieved by computer scientists at the Fraunhofer Institute for Communication, Information Processing and Ergonomics in Germany, The Huffington Post reported.
The finding is of huge concern to computer security firms that currently isolate important machines which have no internet connection, using ‘air gaps’ to protect them.
The computer scientists started investigating the idea of hacking computers using sound by imagining how tech savvy criminals might gain access to the most secure of machines.
They noted that in the past hackers have used ‘parts of the operating system that were not considered for communication’ to gain access to sensitive data’.
Consequently they came up with a hack using sound to steal data from ‘air gap’ protected machines. The researchers chose to use sounds that are too high pitched for humans to hear.
