Just a few weeks ago, a ransomware called WannaCry hit a lot of Windows 7 PCs. The cyberattack happened worldwide and affected alot of institutions like hospitals and other companies. The attack would encrypt the data on the said computer and the culprit would demand a ransom, paid via Bitcoin.
And now, there’s a new bug that causes Windows 7 and Windows 8 PCs to crash. While this doesn’t have the same intensity that the WannaCry attack has, it is still alarming. The bug is said to be similar to the problem found in Windows 95 and Windows 98 before.
Based on a report from Ars Technica, an image file with a name “$MFT” when loaded can cause your PC to slow down. According to the report, a malicious website will try to load the said image file, thus causing a problem on your computer. The NTFS file system uses the “$MFT” for special metadata files, and both Windows 7 and 8 fails to read the directory name correctly.
The Verge tested the filename “c:\$MFT\123” in a website image. The test was carried on a Windows 7 machine, and it crippled the PC afterwards. The system started to slow down until it was restarted. For old time users out there, you can relate this issue with the “c:\con\con” that would crash the Windows 95 and Windows 98 machines.
The new bug doesn’t affect Windows 10 PCs and it has already been reported to Microsoft.
