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
Slug
Short identifier for the tag. Useful in queries and API lookups.
Source Bytes
Number of bytes sent from source IP. Useful for traffic analysis.
Source Country
Country where the IP is registered. Provides attacker infrastructure location context.
Source Country Code
ISO country code for the IP’s registration country.
Source Country Count
Count of IPs originating from each country. Useful for geo-distribution of attacks.
Source Latitude
Latitude of IP’s registered location. Useful for geo-mapping.
Source Longitude
Longitude of IP’s registered location. Useful for geo-mapping.
Spoofable
Shows whether the IP completed a valid TCP handshake. If false, traffic may be spoofed or fake.
Spoofable Count
Count of spoofable vs. non-spoofable IPs. Highlights volume of potentially fake traffic.
Tags Count
Count of IPs associated with specific tags. Helps identify common behaviors at scale.
Timeline
Key timeline details about when the CVE was published, updated, and added to CISA (https://www.cisa.gov/known-exploited-vulnerabilities-catalog). Useful for understanding how long the issue has been known.
Timeline CISA KEV Date Added
Date the vulnerability was added to CISA’s Known Exploited Vulnerabilities (KEV) catalog. Vulnerabilities in KEV should be prioritized for remediation per federal guidance.
Timeline CVE Last Updated Date
The last date the CVE entry was updated in the database. Useful for tracking changes in severity, affected products, or exploit status.
Timeline CVE Published Date
The date the CVE was first published. Helps determine how long attackers have potentially been aware of the vulnerability.
Timeline First Known Published Date
Date when the first exploit associated with the CVE was published.
Tor
Identifies if the IP is a Tor exit node. Tor traffic often indicates obfuscation or anonymization.
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.
