Are you blind to the next big firewall exploit? Warning signs and lessons learned from the recent Cisco exploit

It feels like the security world is caught in a recurring cycle. We see a spike in strange scanning activity, file it away as internet background noise, and then weeks later, a major zero-day exploit drops, targeting the very technology that was being scanned. The recent Cisco ASA vulnerabilities were a textbook example of this pattern. A September 4, 2025, report from GreyNoise highlighted a massive surge in scanning, with over 25,000 unique IPs probing Cisco ASA devices.

How do you find an adversary who lives where you can't easily look? A recent CISA advisory on the state-sponsored actor "Salt Typhoon" highlights this exact challenge. These actors aren't just breaking in; they're moving in. They persist on network edge devices like routers and firewalls—critical infrastructure that often sits outside the view of traditional endpoint security. From this vantage point, they capture traffic, steal credentials, and plan their next move.
