  • File system monitoring:
  • Network monitoring:
  • Heuristic/ML detection:
  • Use updated YARA rules and EDR detections for known family signatures.

    • WinLocker Builder 0.6 represents a low-tech but high-impact malware builder from the late 2000s. Unlike modern ransomware (e.g., WannaCry), it does not encrypt files. Instead, it relies on UI manipulation, registry persistence, and social engineering. This paper dissects the builder’s architecture, evasion techniques, and its surprising relevance to modern “support scam” toolbars.

    | Feature | WinLocker Builder 0.6 | Modern RaaS (e.g., Dharma) | |------------------------|----------------------|-----------------------------| | Encryption | None | AES-128 + RSA | | C2 communication | None (static unlock) | Tor/HTTP POST | | Privilege escalation | None | UAC bypass (CMSTPLUA) | | Anti-sandbox | None | Sleep/debug checks | | Typical ransom | $10 (SMS) | $500–$2000 (BTC) |
