Compliance Node Overview
MITRE ATT&CK T1090.002 (External Proxy) is an Enterprise Command and Control sub-technique of T1090 (Proxy). Adversaries may use an external proxy to act as an intermediary for network communications to a command and control server to avoid direct connections to their infrastructure. Many tools exist that enable traffic redirection through proxies or port redirection, including HTRAN, ZXProxy, and ZXPortMap. Adversaries use these types of proxies to manage command and control communications, to provide resiliency in the face of connection loss, or to ride over existing trusted communications paths to avoid suspicion. Affected platforms: Linux, macOS, Windows, Network. MITRE-documented mitigations include M1031 Network Intrusion Prevention. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-03, AC-04, CA-07, CM-02, CM-06, CM-07, SC-07, SC-08.
