  "bluf": "MITRE CAPEC-158 (Sniffing Network Traffic) is a detailed-level attack pattern in the MITRE Common Attack Pattern Enumeration and Classification. In this attack pattern, the adversary monitors network traffic between nodes of a public or multicast network in an attempt to capture sensitive information at the protocol level. Network sniffing applications can reveal TCP/IP, DNS, Ethernet, and other low-level network communication information. The adversary takes a passive role in this attack pattern and simply observes and analyzes the traffic. Likelihood of attack: Unknown. Typical severity: Medium. Maps to weaknesses CWE-311. Relates to MITRE ATT&CK T1040, T1111.",
