Microsoft has a security issue that affects both Windows 7 and Windows 10 operating systems. The code exploits a vulnerability in Microsoft's handling of NTFS filesystem images and was discovered by Marius Tivadar, a security researcher with Bitdefender. He reported the issue to Microsoft but was not heard. This video dates back towards Summer 2017. Now, he's stepping out with details and a demonstration to raise awareness of this vulnerability. Microsoft downgraded the bug's severity because exploiting it requires either physical access or social engineering (tricking the user). The researcher doesn't agree with Microsoft's decision. The exploit is nasty because Tivadar's proof-of-concept shows he can force a BSOD, even with Windows locked. It literally takes 2 to 3 seconds to crash the OS and is still present, even with Windows 10 version 1803 - the April 2018 Update. Have a peek at the video.
