Summary

Bob Rudis, VP Data Science from GreyNoise, is sharing some insights into their work on "Early Warning Signals: When Attacker Behavior Precedes New Vulnerabilities." New research reveals a striking trend: in 80% of cases, spikes in malicious activity against enterprise edge technologies like VPNs and firewalls occurred weeks before related CVEs were disclosed. The report breaks down this “6-week critical window,” highlighting which vendors show the strongest early-warning patterns and offering tactical steps defenders can take when suspicious spikes emerge. These findings reveal how early attacker activity can be transformed into actionable intelligence, enabling defenders to anticipate and neutralize threats before vulnerabilities are publicly disclosed. Complete our annual ⁠⁠⁠audience survey⁠⁠⁠ before August 31.

0:31.6	So rethink your future with the degree you didn't think was possible.
0:35.6	The Open University, the future is open.
0:45.3	Hello everyone and welcome to the CyberWires Research Saturday. I'm Dave Bittner, and this is our
0:51.6	weekly conversation with researchers and analysts
0:54.3	tracking down the threats and vulnerabilities, solving some of the hard problems and
0:59.1	protecting ourselves in a rapidly evolving cyberspace.
1:02.9	Thanks for joining us.
1:09.5	Within the past two years, we've had this what what I will call, anac data or gut calls, that, wow, we get this weird spike on some piece of usually enterprise-grade edge technology.
1:22.3	And then, like, you know, stick in your head that there was a spike.
1:24.8	And then, wait, wait, there's a really interesting or bad or just new set of CVEs that come out, like really short period of time later that are either
1:33.0	bad or do require patching by folks out there. And like, that's happened time and time again.
1:39.3	That's Bob Rudas, VP of Data Science at Grey Noise, the research we're discussing today is titled
1:45.3	Early Warning Signals, when attacker behavior precedes new vulnerabilities.
1:57.2	So earlier this year, we started to say that in our blog posts.
