Remediation Steps:
Immediately isolate the affected system, perform a full system scan with updated endpoint security software, and thoroughly investigate and remove all detected persistence mechanisms (e.g., scheduled tasks, registry modifications, startup entries). Monitor network activity for C2 communication and consider reimaging the system if complete eradication cannot be confirmed.
