Log into most any Linux system by hitting backspace 28 times
Security researchers have discovered a ludicrously simple way to hack into a number of Linux distributions: Just tap the backspace key 28 times in a row. A team from the Cybersecurity Group at Polytechnic University of Valencia (UPV) in Spain found that doing so for builds utilizing the ubiquitous Grub2 bootloader — that’s to say just about all of them — immediately bypasses the lock screen, initiates the “Grub rescue shell” and grants the user access to the system for whatever nefarious .
The team found that the backspace trick triggers a memory error, which in turn launches the rescue shell. The bug isn’t a huge threat — I mean, a hacker would need physical access to your machine in order to exploit it — especially now that Ubuntu, Red Hat, and Debian all have released patches.
