Most Exploited | Vulnerability Intelligence

Vulnerability discovery is accelerating with automated tools, AI and LLMs seemingly contributing to a growing number of new findings. For security teams already stretched across patch cycles, alert queues, and audit findings, the real question isn’t how many CVEs got published this week. It is which vulnerabilities are actually likely to have a material impact on the organization’s assets.

The Most Exploited project was created with that question in mind. Rather than tracking every vulnerability from disclosure through its full lifecycle, it focuses on the ones showing new signs of real-world exploitation. Those signs include published proof-of-concept code, exploitation confirmed in vendor advisories and incident write-ups, inclusion in government catalogs of known exploited vulnerabilities, and links to specific threat groups such as ransomware operators.

Only a small share of published CVEs are ever exploited in real attacks. Vulnerabilities that attackers are already targeting, or appear to be preparing to exploit, can therefore be a useful starting point for prioritization. Identifying these signals early can give teams more time to investigate, prioritize, and remediate affected assets before exploitation becomes widespread.

To find those signals, the Most Exploited project monitors a broad range of trusted sources. These include Five Eyes cyber agencies, national CERTs, vendor advisories, leading security researchers, and reputable cybersecurity news outlets.

Most Exploited aims to complement an organization’s existing vulnerability intelligence processes and provide additional context, such as evidence of active exploitation, links to threat groups like ransomware operators, and the availability of proof-of-concept code.
