SPR: A team of security researchers have successfully demonstrated that the standard equipment inside computers, printers and other devices could be hacked to send information out of the offices as sound waves. Recently, this sound wave hacking was demonstrated at Black Hat conference in Las Vegas.
Since a very long time, security researchers, hackers and scientists have developed new and innovative ways to transmit data by making use of light, heat, electrical signals and other things. According toReuters, in a recent development, a group of security from U.S. have demonstrated hijacking of computers and other devices at the annual security conference Black Hat in Las Vegas on Wednesday.
This team was lead by Ang Cui, the lead researcher at Red Balloon security, who will release a “proof-of-concept” code afterwards that will provide us more knowledge about the manipulations made in this sound wave hacking.
Reuters writes that this sound wave hacking is done by overtaking the control of the input-output circuits and then vibrates at a frequency set by the researchers. Then, these sound vibrations could be caught using a simple AM radio antenna from a small distance. This technique could be used to manipulate the data and target a machine like computers, printer or another device.
Lead researcher Ang Cui calls the makeshift antenna a “Funtenna” that adds another potential channel to make this sound wave hacking hard to detect. This will make it hard to get caught in traffic logs while leaving the building. Cui said that they would need to develop some way to enter into the targeted system, find the data and convert it into the desired data format for transmission.
More information about this sound wave hacking will be released later, but this development indicates the increasing threat and unpredictable ways of attacks.
