In cybersecurity, staying ahead of actively exploited vulnerabilities is a continuous challenge. The CISA Known Exploited Vulnerabilities (KEV)Â catalog highlights CVEs confirmed to be actively exploited in the wild, posing immediate risks to organizations. Monitoring these vulnerabilities effectively is critical but often overwhelming due to the volume of data and the dynamic nature of threats.
To address this challenge and strengthen your cyber intelligence-in-depth approach, DigitalStakeout has expanded its threat data streams with the introduction of the Exploited CVE Feed. This feed provides real-time insights into KEVs, integrating seamlessly with our existing suite of threat intelligence feeds. In this blog post, we'll explore how the Exploited CVE Feed enhances KEV monitoring and how it fits into a comprehensive threat intelligence strategy alongside our other data feeds.
The Critical Importance of Monitoring KEVs
The KEV catalog is a curated list of vulnerabilities that are actively exploited, requiring immediate attention from security teams. Focusing on KEVs is essential because:
Immediate Risk: These vulnerabilities are being used by threat actors right now.
Compliance Requirements: Organizations may need to address KEVs to meet regulatory standards.
Resource Prioritization: Emphasizing KEVs ensures that limited resources target the most pressing threats.
However, challenges in monitoring KEVs include:
Information Overload: The vast amount of data can obscure critical details.
Lack of Context: CVE entries may not provide actionable information.
Rapid Threat Evolution: New exploitation methods and actors emerge frequently.
How the Exploited CVE Feed Enhances KEV Monitoring
The Exploited CVE Feed is designed to simplify KEV monitoring by offering:
Real-Time Updates: Aggregates information related to KEVs from diverse sources continuously.
Contextual Insights: Provides enhanced metadata and automated tagging for better understanding.
Customizable Feeds: Allows tailoring based on specific technologies, vendors, or vulnerability types.
By integrating this feed into your security operations, you gain a focused tool that brings clarity to the complex task of vulnerability management.
Expanding Intelligence-in-Depth with DigitalStakeout's Threat Data Feeds
The Exploited CVE Feed is part of DigitalStakeout's broader commitment to providing layered threat intelligence. Our platform offers access to pre-filtered intelligence from across the digital landscape, consolidating various data sources into a unified interface. Here's how our feeds contribute to an intelligence-in-depth strategy:
Purpose: Processes exposed credentials and compromised records from breach disclosures and data dumps.
Benefit: Helps you identify if your organization's data has been compromised, allowing for prompt remediation..
Purpose: Tracks exposed personal information and data broker listings across the web.
Benefit: Alerts you to the exposure of sensitive personal data belonging to employees or customers.
Purpose: Tracks over 10,000 daily global events and incidents across 14 risk categories.
Benefit: Provides situational awareness of events that could impact your organization's operations or security posture.
By incorporating the Exploited CVE Feed alongside these existing feeds, you enhance your ability to detect, analyze, and respond to a wide range of threats, reinforcing your overall cybersecurity strategy.
Key Features of the Exploited CVE Feed

Vulnerability Patch: Information about available fixes or patches.
Vulnerability Mitigation: Suggested methods to reduce or eliminate the vulnerability's impact.
How To Exploit Vulnerability: Instructions or guides on exploitation methods.
Target of Exploit: Systems or applications vulnerable to the CVE.
Industry Target: Sectors likely to be specifically targeted by the exploit.
Zero-Day Exploit: Discussions of exploitation before public disclosure or patch release.
Exploit Kits: Tools used for mass exploitation of the CVE.
Proof of Exploit: Evidence showing the CVE has been used in attacks.
Threat Actor: Information about groups or individuals exploiting the CVE.
Ransomware Use: Details on the CVE's use in ransomware campaigns.
APT Use of Exploit: Indications that Advanced Persistent Threat groups are leveraging the CVE.
Benefit: These tags allow analysts to quickly gauge the severity and relevance of a CVE, streamlining the decision-making process.
