  "bluf": "MITRE ATT&CK T1020.001 (Traffic Duplication) is an Enterprise Exfiltration sub-technique of T1020 (Automated Exfiltration). Adversaries may leverage traffic mirroring in order to automate data exfiltration over compromised infrastructure. Traffic mirroring is a native feature for some devices, often used for network analysis. For example, devices may be configured to forward network traffic to one or more destinations for analysis by a network analyzer or other monitoring device. Adversaries may abuse traffic mirroring to mirror or redirect network traffic through other infrastructure they control. Affected platforms: Network, IaaS. MITRE-documented mitigations include M1041 Encrypt Sensitive Information, M1018 User Account Management, M1057 Data Loss Prevention. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-02, AC-03, AC-04, AC-06, AC-16, AC-17, AC-18, AC-19.",
