Edge Devices Are Your Cyber Underbelly. Here’s Why.

This podcast transcript summarizes GreyNoise Intelligence’s 'State of the Edge' research showing a surge in attacks against edge devices (firewalls, VPNs, routers, LLM endpoints). It documents large-scale scanning and exploitation — including campaigns attributed to Russia’s FSB and massive residential botnets (hundreds of thousands of IPs) used for credential spraying — driven largely by unpatched or end-of-life software and weak configurations. GreyNoise emphasises behavioral detection (honeypot telemetry, JAW4 fingerprints), dynamic blocklists, and early-warning signals (median ~11 days before CVE disclosure) as practical mitigations.
