This technique has been deprecated. Please use Non-Standard Port where appropriate.
Adversaries may communicate over a commonly used port to bypass firewalls or network detection systems and to blend with normal network activity to avoid more detailed inspection. They may use commonly open ports such as
- TCP:80 (HTTP)
- TCP:443 (HTTPS)
- TCP:25 (SMTP)
- TCP/UDP:53 (DNS)
They may use the protocol associated with the port or a completely different protocol.
For connections that occur internally within an enclave (such as those between a proxy or pivot node and other nodes), examples of common ports are
- TCP/UDP:135 (RPC)
- TCP/UDP:22 (SSH)
- TCP/UDP:3389 (RDP)
