Nightmare-Eclipse Strikes Again with 'ShieldCrash' Windows Exploit

A researcher has released another zero-day exploit for Windows Defender as part of an ongoing campaign against Microsoft. This exploit is associated with the Nightmare-Eclipse group and is referred to as ShieldCrash. The researcher's actions appear to be motivated by a grudge against the company. The publication of this exploit follows previous releases by the same individual. The exploit targets a vulnerability in Windows Defender.
