A bug in NTFS causes a blue screen in Windows

A new potentially dangerous NTFS bug is found in Windows 7 and older. The exception is only the latest 10-th release. This problem was previously present in earlier versions of MS OS 95/98. And now it’s coming back. An error is caused by hidden metadata file named $MFT. One is part of each root dir in NTFS-volume. It differs from ordinary hidden ones. Metadata files are not available for both a user and non-system programs. As a result, any attempts opening metadata file are blocked by OS.

This feature can be used by hackers to OS crash by calling a blue screen. One can use $MFT-name as a directory in the path to any file. For example, by visiting website, a user may be redirected to c:\$MFT\crash.txt. Then, NTFS-driver unlocks metadata file in the root dir of sys-drive. Contrary to that, OS still expects an object to be locked back and stops responding to any actions. A forced reboot helps with resolving this situation.

However, Windows-10 users do not need to worry. Their system is free from NTFS-bug. The rest, may caught up on hacker tick even just by going to URL containing $MFT-text. The good news: that NTFS-bug is not able to do serious harm: theft of confidential info, for example.
