Choosing the right OS for your computer can be quite a pain in the neck. There are quite a lot of them out there, each one with its own pros and cons. Some of us would look forward to Windows’s stunning graphics and amazing performances while others search for functionality. Whatever you’re looking for (apart from the droids!), Linux seem to be the perfect solution. Only thing is that Linux’s bug leaves the system vulnerable to hacker attacks.
Recently a group of techies, hailing from the Cybersecurity group, which is a part of the Polytechnic University of Valencia, has discovered a critical flaw in Linux’s backdoor security protocols. As other would put it, even a ten-year-old can hack your computer and steal your data, all because of a simple bug.
According to the Cybersecurity group, a user or rather a mischievous user can simply bypass your password screen by simply hitting the backspace key 28 times in a row. As the techie group explains, once a user hits the backspace key, the operating system returns a critical error.
Once this happens, the Grub rescue shell is initiated, and through this shell, the user can have access to any number of critical systems, including the contents stored on the local hard-drive.
A hacker can use this window of opportunity in order to destroy all the data on the hard-drive or install a rootkit which is capable of accessing your computer remotely.
Moreover, as the security group stressed out, it doesn’t matter if your have a BIOS lock or not. The Grub rescue shell is very similar to Windows’s safe mode, which you can use in order to restore lost data or uninstall undesired programs, which can’t be uninstalled using common procedures.
Of course, as the group added, this procedure would come in handy for someone who wants to steal of destroying your data, but it can also impede his plan. That’s because the said procedure requires the hacker to physical interact with your computer in order to get desired results.
We are unsure whether someone had problems because of this minor flaw, but it does point out that even complex security protocols can be easily bypassed if one looks for simple solutions.
But, according to many tech specialists, the odds of this scenario taking place are very low. And even if it were to happen, the new patches are there to ensure that no one can steal the data from your computer.
