Noise Letter April 2025
Summary: GreyNoise's April 2025 NoiseLetter describes attackers exploiting "resurgent vulnerabilities" - older flaws that were deprioritized years ago or never seen as serious, now being opportunistically exploited at scale rather than as zero-days. The newsletter says these flaws concentrate in edge technologies like firewalls, routers, and VPNs, the internet-facing assets attackers use for initial access and persistence.
Why it matters: The flaws drawing attacker interest are ones many teams already chose to deprioritize, sitting on the firewalls, routers, and VPNs that are the front door to the network.
