Abstract
A method of generating a baseline of expected behavior on a single machine or endpoint to accurately fingerprint the native behavior of the NTLM protocol on that particular endpoint in a network. By limiting the scope of a baseline to a single endpoint, the scope of the baseline can consist of expected behavior (including supported hash functions, version strings and various feature flags). Deviations from these behaviors are considered evidence of a redundant implementation of NTLM utilized by an attacker and thus as evidence of an attempted PTH attack. Using this method it is possible to accurately detect PTH attacks originating from all publicly known non-standard implementations of NTLM existing in tools such as Impacket, Metasploit, and Invoke-TheHash.
