New! PHP2Shell: Successful exploitation observed against a vulnerable GreyNoise sensor
Microsoft Copilot for Security combines generative AI with threat intelligence data to help teams investigate and respond to threats. GreyNoise adds real-time edge observability and context on IP addresses, internet scanning activity, and attacker behavior, helping analysts identify emerging threats and prioritize response efforts.
Pre-built GreyNoise plugin capabilities bring IP investigation, business service identification, internet scanning analysis, threat hunting, and CVE research directly into Microsoft Copilot for Security.
High outbound connection volumes make it impractical to investigate every anomalous event, allowing connections from internal assets to malicious infrastructure to go unnoticed. When an internal host successfully connects to infrastructure GreyNoise has observed conducting mass scanning or exploitation, it can indicate compromise. The activity may signal C2 beaconing, data exfiltration, or botnet participation and warrants immediate investigation.
Ask Microsoft Copilot for Security to look up destination IPs from outbound firewall, proxy, and EDR telemetry using the GreyNoise plugin. Copilot returns GreyNoise context that helps analysts determine whether an internal asset communicated with infrastructure observed conducting malicious activity and identify hosts that require immediate investigation or containment.
Authentication failures and brute-force attempts are constant for perimeter devices. Without external context, analysts struggle to distinguish opportunistic account access from attempts aimed specifically at their organization. Hosts conducting mass scanning or operating as part of botnet or proxy infrastructure authenticate to VPNs and identity providers, and
existing detection logic doesn't flag it.
Query source IPs from successful and failed authentication events in Microsoft Copilot for Security using the GreyNoise plugin. GreyNoise context helps analysts escalate successful logins from malicious infrastructure and investigate failed attempts that may indicate active targeting of their organization’s identity infrastructure.
Misconfigured firewall rules, outdated access controls, and overly permissive policies can allow malicious traffic through the perimeter. Without external threat intelligence, analysts may not recognize when an allowed inbound connection originated from known threat infrastructure.
Ask Microsoft Copilot for Security to investigate source IPs from allowed firewall, WAF, or proxy events using GreyNoise. The resulting context helps analysts identify connections from malicious or suspicious infrastructure and determine which perimeter controls may require investigation or remediation.
Internet-facing systems generate large volumes of alerts from automated scanners, bots, and opportunistic exploitation attempts. This background noise consumes analyst time and makes events that require immediate attention harder to identify.
Query source IPs from perimeter alerts in Microsoft Copilot for Security using GreyNoise Quick IP and Business Services lookups. GreyNoise context helps analysts distinguish known internet scanners and common business services from IPs that require further investigation, resolve routine alerts faster, and focus on malicious IPs that may represent targeted activity.
