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.
