Overview

GreyNoise accelerates investigations by adding context on IPs and CVEs seen in mass scanning and exploitation campaigns. This enrichment speeds triage, reduces manual work, and helps SOC teams more effectively investigate timelines and the scope of incidents.

How GreyNoise Speeds Up Investigations

Enriched Threat Context

GreyNoise shows whether an IP is scanning broadly or targeting specific systems, helping analysts gauge threat levels.

Identify Exploitation Attempts

CVE tags reveal which vulnerabilities are being exploited and which assets are likely targeted.

Map Attack Infrastructure

GreyNoise links IPs, ASNs, and behaviors so analysts can pivot and see the broader campaign.

Strengthen Containment Decisions

Intelligence on attacker infrastructure helps teams decide when to block, monitor, or expand containment.

Speed Up Timeline Construction

Data on first seen, last seen, and behavior give provides evidence for accurate incident timelines.

Better Documentation and Reporting

Enriched incident reports clarify what happened and why it matters.

NAME
Description & Use
Destination Countries Count
Count of IPs targeting specific countries. Supports geo-threat monitoring.
Destination Country Codes
ISO codes for countries targeted by scanning. Supports correlation with geo-based IOCs.
Details
Basic CVE details, including CVSS score (Common Vulnerability Scoring System), associated products & vendors, and NIST CVE recognition status. Provides context on the vulnerability itself.
Details CVE CVSS Score
CVSS score assigned to the CVE. Commonly used in risk scoring but should be weighed alongside exploitation activity.
Details Product
The product affected by the vulnerability (e.g., Apache HTTP Server). Used to match against an organization’s asset inventory for prioritization.
Details Published to NIST NVD
Indicates if the vulnerability is published in the NIST National Vulnerability Database. Confirms official recognition and ensures compatibility with standard risk feeds.
Details Vendor
The vendor or developer responsible for the affected product. Helps map vulnerabilities to vendor patch advisories and SLAs.
Details Vulnerability Description
Summary of what the vulnerability is and how it works. Helps analysts understand potential impact and determine exploitability in their environment.
Details Vulnerability Name
Human-readable name of the vulnerability. Practitioners use this for quick recognition when scanning advisories.
Domain
Domain tied to the ASN owner. Provides higher-level ownership context.
Exploitation Activity
Observed IPs scanning or exploiting the vulnerability today, in the last 10 days, and the last 30 days.
Exploitation Activity Benign IP Count (10d)
Total number of benign IPs GreyNoise observed scanning or exploiting this vulnerability in the last 10 days.
Exploitation Activity Benign IP Count (1d)
Total number of benign IPs GreyNoise observed scanning or exploiting this vulnerability today.
Exploitation Activity Benign IP Count (30d)
Total number of benign IPs GreyNoise observed scanning or exploiting this vulnerability in the last 30 days.
Exploitation Activity Seen
Whether GreyNoise has observed activity related to this CVE.
Exploitation Activity Threat IP Count (10d)
Total number of threat IPs GreyNoise observed scanning or exploiting this vulnerability in the last 10 days.
Exploitation Activity Threat IP Count (1d)
Total number of threat IPs GreyNoise observed scanning or exploiting this vulnerability today.
Exploitation Activity Threat IP Count (30d)
Total number of threat IPs GreyNoise observed scanning or exploiting this vulnerability in the last 30 days. Useful for long-term prioritization and trend analysis.
Exploitation Details
Exploitation-related details pertaining to attack vector category, EPSS score (Exploit Prediction Scoring System), available exploits, and KEV (Known Exploited Vulnerabilities) registration. Guides whether to prioritize based on real-world attacker use.
Exploitation Details Attack Vector
The method attackers use to exploit the vulnerability (e.g., network, local, adjacent). Helps assess exposure across internet-facing vs. internal assets.
Exploitation Details EPSS Score
EPSS score (Exploit Prediction Scoring System) associated with the exploitation.
Exploitation Details Exploit Found
Indicates whether a working exploit is publicly available. Confirms attacker capability and should increase remediation priority.
Exploitation Details Registered in KEV
Whether exploitation has been registered in the KEV (Known Exploited Vulnerabilities) database.
Exploitation Stats
Statistical data about exploitation, including number of exploits available, and number of threat actors and botnets exploiting the vulnerability.
Exploitation Stats Number of Available Exploits
Total number of exploits available (public + commercial).
Exploitation Stats Number of Botnets Exploiting Vulnerability
Total number of botnets exploiting the vulnerability.
Exploitation Stats Number of Threat Actors Exploiting Vulnerability
Total number of known threat actors exploiting the vulnerability.
First Seen
Date the IP was first observed by GreyNoise. Indicates activity lifetime.
ID
Unique tag identifier.
ID
Unique identifier for the record. Used to track and reference the vulnerability consistently across systems and reports.
IP
The observed IP address itself. Primary entity to investigate or correlate across alerts.
Intention
Tag’s intent classification: benign, malicious, suspicious, or unknown. Adds risk context.
