Security researcher Abdelhamid Naceri, known as Nightmare Eclipse, released the SignDrop zero-day exploit targeting Windows systems this week. The tool abuses Windows Common Log File System logic to elevate local user privileges to System. Testing confirms it works on Windows 11 26H2 and Windows Server 2025 Experimental, affecting 80% of global installations if the system is older than 90 days.
