status: test
description: This rule flags creation of the LiveKdD.SYS driver in C:\Windows\System32\drivers when the creating process is livekd.exe or livek64.exe. Attackers may use LiveKD to enable live kernel debugging while operating in a stealthy manner and with elevated capabilities. It relies on Windows file event telemetry that records the target driver path and the process image that created the file.
