Grey Noise Uncovers Unique Risks From Resurgent Cybersecurity Vulnerabilities

Summary: GreyNoise research describes a class of "resurgent vulnerabilities" - older flaws that were deprioritized or never seen as serious and are now being opportunistically exploited at scale, often in edge technologies like firewalls, routers, and VPNs. These flaws are not being exploited as zero-days, and the spikes in activity around them rarely make headlines.

What you should know: The internet-facing assets attackers use for initial access and persistence - firewalls, routers, VPNs - are the same ones carrying flaws your team may have closed out years ago, and the renewed exploitation is quiet enough that it rarely surfaces in the news.
