Pulsar RAT Using Memory-Only Execution & HVNC to Gain Invisible Remote Access

Pulsar RAT is a sophisticated, fileless Windows remote access trojan descended from Quasar that uses memory-only execution, HVNC, anti-VM/debugging, UAC bypass, scheduled-task persistence, credential theft (Kematian Grabber), keylogging, clipboard hijacking, and modular plugins; recent campaigns distributed it via compromised supply-chain (malicious npm packages) and multi-RAT drops, posing a high operational impact and requiring layered detection and response measures.
