In today’s day and age, security systems are being beefed up to ensure that there is no error or mistakes being made when it comes to security. However, even in times like today, there are sometimes mistakes which surprise us due to their simplicity! Sometimes we’re left dumbstruck on how something so simple could become something so dangerous. These things are more often than not a lack of judgement, or simple mistakes which one does not even think they’re committing! Linux has become the latest victim of such a mistake, and due to this, to hack Linux OS has now become quite a cakewalk for those with a basic knowledge of programming.
As per latest reports that have rolled in after a research done by two researchers from the Polytechinc University of Valencia in Spain. The report is quite shocking, as it reveals that a combination of keystrokes can help you break into and hack Linux OS and steal data, erase data and inject malware into it! Now you must probably be thinking it requires a complex series of codes and that’s the keystrokes we are talking about. No! All it takes is just hitting the back-space key 28 times to gain access of the Grub2, which is actually the bootloader which helps initialize most systems that run on Linux. A security report has been released by the duo who found this out, it can be read by clicking HERE.
“The attacker is able to destroy any data including the grub itself. Even in the case that the disk is ciphered the attacker can overwrite it, causing a [denial of service],” the report reads.
Hector Marco and Ismael Ripoll, the two researchers who discovered this said:
“To quickly check if your system is vulnerable, when the Grub ask you the username, press the Backspace 28 times. If your machine reboots or you get a rescue shell then your Grub is affected,” they write.
