| Explanation | plugin source hardcodes a raw IPv4 URL (e.g. `https://94.156.79.8/...`) — legitimate plugins use DNS hostnames because IPs change. Hardcoded IPs in plugin code are almost always either dev leftovers or attacker C2 infrastructure. The June 2024 social-warfare keylogger (audit #14) used `https://94.156.79.8/sc-top.js` for the JS payload host, `/AddSites` for victim registration, `/CMSUsers` for filesystem-recon exfil. Operator infrastructure on raw IPs avoids domain registration / RDAP detection paths. Post-filtered to skip RFC1918/loopback/link-local ranges and `vendor/`/`tests/` paths. |
