Most modern computers were vulnerable to an attack aimed at stealing confidential data. This is reported in a new study of the company F-Secure .
Security consultant Olle Segerdahl (Olle Segerdahl) said that hacking will take only five minutes from the attacker. However, for this, it needs physical access to the device.
Vulnerability allows criminals to perform a cold reset attack. It consists in turning off or restarting the computer without stopping the running tasks. After that, the hacker recovers the data that was left in the RAM.
Modern devices are able to rewrite their main memory, but Segerdal found a way to disable this process. It turned out that the settings that control it are not immune to physical interference. An attacker can disable overwriting and launch an attack using an external USB drive.
The consultant pointed out that such attacks will most often be aimed at lost laptops. Of particular interest to hackers are the work devices of employees of companies that can be used to hack corporate networks.
The results of his research Segerdal sent to Apple , Microsoft and Intel . He stressed that solutions to this problem have not yet been found.
