Stealing Computer Data through Speakers is Possible Now!

+




It is learnt that the computer data can be fetched from your system in the form of audio signals. This is new happening, which was not possible previously and nobody was ready to make sure over it.

The new research has been made in Germany in which they developed the latest and unique computer malware. This computer can stead the data, password or login information from the PC and helps to transfer the data in the nearby computer system in audio signals. The audio signals are beyond the human hearing range and nobody can get the frequency of this audio signals.

They managed to publish this features in the Journal of Communication. This research work was carried out by the teams of the Fraunhofer Institute for Communication, Information Processing and Ergonomics Germany.

The two researchers including Michael Hanspach and Michael Goetz used the built-in speakers and microphones for the transmission of computer passwords and other data with the speed of 20 bits per second within the range of about 20 meters. It also allows the computer malware to use the critical data to the outside.

Computer Data Transfer

Stealing  Computer Data

Most of the time, speakers and microphones are not given the importance while making the security planning and the frequency of audio is also beyond the range of human being. It is also not easy to detect the transfer of data from any computer system, especially when there various other computer system, which are working in the crowded workplace.

This analysis has been made with the use of five Lenovo T400 laptops, which run on the Debian 7.1 and they also performed working in the standard computer lab & no particular unusual audio features are found. The experiment was done by sending the 20 kHz and during the transmissions, the inaudible sound was found beyond the capability of human being. The frequency of sound can be higher or lesser and it cannot be caught and the range of the broadcasting can be lessen.

When this experiment was carried out it was found that the researchers used the keystrokes at one computer and broadcast this sound over audio. They used the chain of the computer to pass the sound to the machines connected with the internet. They also sent back the malicious attackers with the fact that slow transmission is being used.

Along with the provision of keystroke information, you can also forward the security critical data like private encryption keys or the text files having small size with the sensitive information can be transferred through the audio signals.

Now you can disconnect the built-in speakers and mics from your computer systems to save and protect your system being used for the transfer of data through audio signals.

Training is being given to the dog s to sniff the presence of drugs and bombs or other dangerous material and now we will also give them training to sniff our computers or hear the Malwares.

Now NSA is thinking over it that this new and latest technique can be implemented in the world.
