For hacking a computer on Linux, it's enough to press "Backspace" 28 times

This hack is so brilliant that it seems fake. You did not misunderstand: for hacking a computer with Linux on board, you just need to press the Backspace key enough times - 28, to be exact. This is definitely a huge drawback for the operating system, which is the choice of many computer geeks and snobs.

The found bug allows you to bypass the password blocking system boot and get full access to the Grub console. With this console, hackers can access all data stored on the computer, install spyware, delete files. The vulnerability was discovered by two researchers from the group of cybernetic security of the Polytechnic University of Valencia.

Researchers specify that the vulnerability in the Grub console affects Linux systems from 2009 to the latest versions. Most major Linux distributors, including Debian and Ubuntu, have already released an urgent patch that eliminates this bug. It is reported that pressing the Backspace key 28 times resulted in an integer overflow of the memory buffer, which allowed to get full access to the system without entering a password.
