Rapuncel NvFsFilter Service Persistence with Repeated AV/EDR Kills
Detects the installation and loading of a suspicious driver named 'NvFsFilter' (nvfsflt64.sys), accompanied by registry persistence and suspicious process termination events. This pattern is characteristic of a 'kill-loop' persistence mechanism where malicious drivers or services repeatedly terminate security agents (AV/EDR) to maintain a persistent foothold on the endpoint.
