Cyber Security Specialistsactively use hacker methods to verify the security of data storage systems and identify potential methods of unauthorized entry into computer systems. Famous for their original developments in the field of computer security, experts from David Ben-Gurion University in the Negev (Israel) presented a new unusual way to steal information from a computer using a power supply.
The hacking technique was called POWER-SUPPLaY,and its implementation will not require special equipment. You can even hack computers that are not connected to the Internet and work offline. To steal data from a computer, the power supply of the hacked computer and special software embedded in the device are used.
Malicious application while reading informationmodifies the load on the central processor, increasing the energy load, which in turn leads to a change in the ultrasonic signals emitted by the components of the power supply. To obtain information transmitted in a silent range, in the form of an ultrasonic morse code, the cracker must be located at a distance of up to 5 meters from the object of attack.
To accept and decrypt the information receivedYou can use a smartphone. The speed of information theft is 22.5 Kb per hour, which is equivalent to a text file with a volume of up to 10,000 words. According to the developer, the purpose of the experiment was to identify a potential way to violate computer protection.
