Threat Hunting | Grey Noise Intelligence
Summary: GreyNoise describes a threat-hunting approach that correlates an organization's internal traffic against its real-time map of internet-wide mass scanning, filtering out opportunistic probes, benign scanners, and botnet noise to surface statistically significant anomalies. The company says this lets hunt teams adopt the PEAK Framework, skip time-consuming research on benign scanning, and link isolated incidents to larger campaigns by mapping attacker infrastructure and connecting logged IPs to those exploiting relevant vulnerabilities.
Why it matters: The pitch rests on a simple claim: most of what your hunters chase is noise from scanners that were never targeting you, and the targeted activity is buried in the remainder. A security leader should ask how much of the team's hunting time currently goes to benign and opportunistic scanning, and whether the signals that matter are being found at all.
