Hack the computer with heat – New Technology

       

The heat generated in a computer can be operated in a manner that allows it to communicate wirelessly with another computer nearby.

The method has been developed by researchers at Ben Guironuniversitetet in Israel that will shortly be publishing a report on the technology dubbed Bit Whisper, writes the University on its website .

In a video, the researchers show how a computer using only the heat radiation could get another computer to rotate, and four of a small toy rocket attached to the attacked computer via USB.

In the controlling computer, a software that is charged to your computer in different ways giving effect to värmeutsrålningen from different circuits which CPU can be controlled and varied. In the computer being attacked is the same software that a hacker managed to install, for example via a usb stick. Thus, the same method used to infect computers with the notorious Stuxnet Trojan.

In the infected computer in the Israeli demonstration used the built heat sensors to detect heat dissipation from the other computer. The install was then able to convert heat fluctuations to a hostile computer code that could be used for communication that can be established in both directions. According Wired sufficient to vary the temperature with only one degree Celsius for generating a digital one or zero in the code which is transmitted through the heat radiation.

The method is still in its infancy and the data rate is only eight bits per hour. But it may be enough to retrieve, for example, a password or a security key and as in the video transmitting the commands that ruled toy cannon.

To it all to work, the distance between the two computers to be more than 40 cm.

A scenario where heat technology can be used is when you want to establish a hostile communication with a computer that is not connected to any external data networks such as the Internet, which is common in the armed forces and banking.
