Neither detail was unusual on its own. A non-standard port. A generic Microsoft HTTP server banner. Plenty of legitimate services run exactly that, so on their own, neither tells you much. Together, they were selective enough to hunt on. https://lnkd.in/e8ER6xpe That is one of the more useful lessons in a recent VMRay blog investigation by independent researchers. Starting from a single #RedLine C2 surfaced through VMRay #UniqueSignal, the analysis pulls the C2's HTTP response from the VMRay's #sandbox and turns one specific pairing, the high port and the server string, into a fingerprint. That fingerprint becomes the pivot: a query against internet-wide scan data to find other hosts sharing it, without ever touching the target infrastructure directly, which keeps the investigation quiet. The full investigation includes every query used, so the approach is reproducible. 🔗 https://lnkd.in/e8ER6xpe #ThreatHunting #CTI #DetectionEngineering #ThreatIntelligence
