Mitigation checklist
Recommended fix / mitigation
- Configure host-based firewalls (e.g., firewalld) or network egress filtering so that the workstation can only initiate outbound RDP connections (typically TCP 3389) to known, trusted internal RDP gateways or corporate servers. Blocking outbound RDP to the wider internet neutralizes the threat of users accidentally connecting to malicious external endpoints.
