What to do now

  1. Check your D-Link model (DNS-320, DNS-320LW, DNS-325, or DNS-340L) and confirm you’re running a firmware version that is at or before 20241028.
  2. Verify whether the device’s web management/account features are reachable from the internet (for example, via remote access or port forwarding).
  3. If the device is reachable from the internet, immediately restrict it (remove port forwarding / VPN-gate access) while you update.
  4. Install the latest D-Link firmware update for your exact model from a trusted source, so you’re beyond the vulnerable release (i.e., later than the fix point 20241028).
  5. After updating, re-check remote reachability and monitor the device for unusual logins or user/account changes.
