Grey Noise Intelligence Releases New Research Linking Cyber Threat Actor Activity to Future Vulnerabilities
Summary: GreyNoise Intelligence released a research report on July 31, 2025, titled "Early Warning Signals: When Attacker Behavior Precedes New Vulnerabilities," examining whether spikes in opportunistic attacker activity against edge technologies precede the disclosure of new CVEs. The company analyzed its tags for CVSS 6+ CVEs tied to edge technologies and observed the pattern only across a specific subset of enterprise edge products from eight vendors, though it did not limit its analysis to enterprise technologies.
Why it matters: GreyNoise's finding that attacker activity often precedes disclosure rather than reacting to it undercuts the reactive model most security programs are built on - and the pattern held for edge products from eight vendors, the perimeter devices defenders can least afford to learn about late.
