title: Windows Process Command Line Indicative of ADCSPwn Use via ADCS Options
id: 5c0296fa-8b14-450e-b961-70affb0cf0f7
status: test
description: This rule flags Windows process creation events whose command line contains ADCSPwn-specific arguments related to Active Directory Certificate Services, including the presence of "--adcs" and "--port". Attackers may use this tool to interact with certificate services in an attempt to coerce authentication and perform certificate-based abuse within an Active Directory environment. Detection relies on process creation telemetry and substring matching on the full command line.
