NIST Updates NVD Operations to Address Record CVE Growth

Security cameras are great at monitoring physical doors, but terrible at locking their own digital ones. Across the internet, thousands of unpatched DVRs sit publicly exposed, many guarded only by the default vendor passwords they shipped with. For threat actors, these are low-hanging fruit. This write-up details a recent two-second Telnet capture, providing a mechanical breakdown of how quickly an exposed camera system goes from online to fully compromised by bad actors.
