Description
Allowing the transmission of NTLM could be part of an NTLM downgrade or an Internal Monologue attack.
Attacker's Goals
Downgrading to a lower NTLM version gives the attacker an easy way to retrieve NTLM hashes from a Windows machine.
Investigative actions
Check whether the executing process is benign, and if this was a desired behavior as part of its normal execution flow.
