The “$MFT” bug can attack a number of vulnerable devices – Windows 7, Windows 8, and the out-of-support Windows Vista running systems can fall prey to this 4 characters bug

“$MFT” bug

The dust of WannaCry Ransomware bug was not even settled yet and a Russian website, Habrahabr.ru has reported a new bug which can attack the vulnerable Windows 7, Windows 8, and the out-of-support Windows Vista running systems. Though the threat is not as big as WannaCry still, it can cause a big mess out of your normally working computer.

How Does This Work?

The hackers only need a combination of 4 characters that is “$MFT” and the computer with older versions of Windows OS will crash. If a developer uses these 4 characters in the directory name where a website stores its images, the system will fall a prey to it. It’s not like the problem has just arrived on the scene, rather the white hat hackers just discovered it. As it was fed in the older versions of Windows to crash when the $MFT command is received because Windows expects this command in a special metadata file used by the NTFS file system. So, to ensure security, the Windows locks the file system as soon as this command is received.

The Consequences

Once a system is attacked by this lock, all succeeding operations in the computer’s to do list will automatically be locked and the programs running on the computer will hang. So when each and every program is hung, it becomes impossible for the system to be used and hence the system is crashed. In the worst case scenario, you can also see a dreaded blue screen of death.

The Solution

The temporary solution for the problem is to restart your computer if you come across this problem. This can cause the loss of your unsaved data and you can get your system back in the right position after a reboot. As far as the Microsoft is concerned, there is no solution released till date regarding this problem. If the users of Windows 7, Windows 8, and Windows Vista want to take a proactive measure, setting up the internet browsers to not load images is the only solution. Obviously, this is not a better solution so we’ll have to wait till Microsoft releases an official update to address this issue.
