Overview

GreyNoise research shows that spikes in traffic targeting older CVEs often precede new CVE disclosures for that same vendor within weeks. These early warnings give organizations time to harden systems, patch, monitor, or block probing IPs.

By detecting shifts in attacker reconnaissance prior to CVE disclosure, GreyNoise provides a critical window of opportunity to prepare before a threat materializes.

How GreyNoise Helps You
Prepare for New CVEs

Provides Time to Prepare

When a new CVE hits critical perimeter systems, it can trigger emergency response and disruption. Early warnings from GreyNoise let teams prepare in advance and minimize impact

Aligns Risk Assessments to Real-World Threat Activity

GreyNoise shows which vendors and technologies are seeing abnormal reconnaissance levels, keeping risk assessments aligned with real-world signals.

Improves Resource Allocation

Defenders can focus investments, patching, and monitoring on upcoming threats most likely to impact them.

‍

Enables Proactive Blocking

Use GreyNoise query-based, dynamic blocklists to stop attacks as your organization patches exposed systems.

NAME
Description & Use
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 Activity Threat IP Count (10d)
Total number of threat IPs GreyNoise observed scanning or exploiting this vulnerability in the last 10 days.
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 Benign IP Count (10d)
Total number of benign IPs GreyNoise observed scanning or exploiting this vulnerability in the last 10 days.
Exploitation Activity Seen
Whether GreyNoise has observed activity related to this CVE.
Exploitation Activity Benign IP Count (1d)
Total number of benign IPs GreyNoise observed scanning or exploiting this vulnerability today.
Exploitation Stats Number of Botnets Exploiting Vulnerability
Total number of botnets exploiting the vulnerability.
Exploitation Activity
Observed IPs scanning or exploiting the vulnerability today, in the last 10 days, and the last 30 days.
Exploitation Stats Number of Threat Actors Exploiting Vulnerability
Total number of known threat actors exploiting the vulnerability.
Exploitation Details Registered in KEV
Whether exploitation has been registered in the KEV (Known Exploited Vulnerabilities) database.
Exploitation Stats Number of Available Exploits
Total number of exploits available (public + commercial).
Exploitation Stats
Statistical data about exploitation, including number of exploits available, and number of threat actors and botnets exploiting the vulnerability.
Exploitation Details Exploit Found
Indicates whether a working exploit is publicly available. Confirms attacker capability and should increase remediation priority.
