Microsoft's own antivirus just got turned into a Windows hacking tool, and there's no patch. A security researcher dropped a working zero-day called "BlueHammer" that abuses Windows Defender itself to hand a normal user complete SYSTEM access on any Windows PC. No CVE. No fix. Just a public GitHub repo and a very angry README. In this video I break down: - What BlueHammer actually is (and why "local privilege escalation" matters more than you think) - The insane exploit chain - fake viruses, frozen antivirus, folder swaps, and password databases - Whether your Windows machine is at risk right now This video is for educational and defensive security purposes only. Do not run exploits against systems you do not own or have explicit permission to test. 🔗 Resources & references: - BlueHammer PoC repo: https://github.com/Nightmare-Eclipse/BlueHammer - Bleeping Computer coverage: https://www.bleepingcomputer.com/news/security/disgruntled-researcher-leaks-bluehammer-windows-zero-day-exploit/ - Exploit Pack technical analysis: https://www.exploitpack.com/blogs/news/blue-hammer-analysis-ms-defender-lpe
