  "bluf": "MITRE CAPEC-313 (Passive OS Fingerprinting) is a standard-level attack pattern in the MITRE Common Attack Pattern Enumeration and Classification. An adversary engages in activity to detect the version or type of OS software in a an environment by passively monitoring communication between devices, nodes, or applications. Passive techniques for operating system detection send no actual probes to a target, but monitor network or client-server communication between nodes in order to identify operating systems based on observed behavior as compared to a database. Likelihood of attack: High. Typical severity: Low. Maps to weaknesses CWE-200. Relates to MITRE ATT&CK T1082.",
