  "bluf": "MITRE ATT&CK T0885 (Commonly Used Port) is an ATT&CK for ICS Command and Control technique. Adversaries may communicate over a commonly used port to bypass firewalls or network detection systems and to blend in with normal network activity, to avoid more detailed inspection. They may use the protocol associated with the port, or a completely different protocol. They may use commonly open ports, such as the examples provided below. Affected asset classes: None. MITRE-documented mitigations include M0804 Human User Authentication, M0931 Network Intrusion Prevention, M0930 Network Segmentation, M0942 Disable or Remove Feature or Program. Operational-technology controls map to NIST SP 800-82 Rev 3 and the IEC/ISA 62443 series.",
