  • Engineer — Act: Active exploitation of a chained vulnerability pair targeting MikroTik RouterOS devices with SSH exposed to the internet; patch RouterOS to the latest stable release immediately and restrict SSH access to trusted management IPs via firewall rules.
  • SOC/IR — Act: Router hijacking via exposed SSH is an assume-breach scenario for any MikroTik devices in the estate; sweep SSH auth logs on edge devices for anomalous logins, and hunt for lateral movement originating from RouterOS management interfaces since disclosure.
  • Leader — Plan: Actively exploited edge-device flaws can expose the entire network perimeter; confirm whether MikroTik equipment is present in the environment and verify the engineering team has a patch plan for exposed devices this week.
