| Component | Observation |
|-----------|-------------|
| Domain | ifangds.com – registered via a privacy‑protected registrar (often from China). The domain resolves to a fast‑flux pool of IPs (mostly 45...* and 103...* ranges). |
| C2 servers | Multiple HTTP(S) endpoints host the secondary payloads. URLs are typically of the form https://<random>.ifangds.com/<hex>.exe. TLS certificates are self‑signed or use free services (Let’s Encrypt) with short lifespans (7‑10 days). |
