  "bluf": "MITRE ATT&CK T1040 (Network Sniffing) is an Enterprise Credential Access and Discovery technique. Adversaries may passively sniff network traffic to capture information about an environment, including authentication material passed over the network. Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data. Affected platforms: Linux, macOS, Windows, Network, IaaS. MITRE-documented mitigations include M1018 User Account Management, M1032 Multi-factor Authentication, M1041 Encrypt Sensitive Information, M1030 Network Segmentation. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-16, AC-17, AC-18, AC-19, CM-07, IA-02, IA-05, SC-04.",
