Windows Defender Vulnerability Allows Malicious File Persistence Through Cloud Tag Detection

Summary

The article describes a GitHub repository called 'RedSun' that documents a Windows Defender vulnerability. The vulnerability involves Windows Defender's behavior when detecting malicious files with cloud tags - instead of removing them, it rewrites the file to its original location. This behavior can be exploited to overwrite system files and gain administrative privileges. The author finds the vulnerability particularly amusing due to the irony of antivirus software ensuring malicious files remain present.
