A Blindspot in Cyber Defense: How Resurgent Vulnerabilities Jeopardize Organizational Security
Summary: GreyNoise describes a class of flaws it calls resurgent vulnerabilities: older issues that were deprioritized or never seen as serious, now being opportunistically exploited at scale rather than as zero-days. The activity concentrates on edge technologies such as firewalls, routers, and VPNs, the internet-facing assets attackers use for initial access and persistence.
Bottom line: The flaws drawing attacker interest are the ones already sitting on your perimeter, and because they are not zero-days and rarely make headlines, they are unlikely to trigger the urgency that new vulnerabilities do.
