Pulsar RAT is a sophisticated, modular remote-access trojan targeting Windows that leverages fileless memory-only payloads, anti-virtualization checks, code injection, hidden VNC (HVNC), and modules for credential and cryptocurrency wallet theft; it spreads via phishing, cracked software and supply-chain compromises (notably 2025 npm packages), retrieves encrypted C2 configurations from public services, and requires layered detection and remediation to mitigate significant operational and data-exfiltration risk.
