Malicious Powershell Process With Obfuscation Techniques Help

You must be ingesting data that records process activity from your hosts to populate the Endpoint data model in the Processes node. You must also be ingesting logs with both the process name and command line from your endpoints. The command-line arguments are mapped to the "process" field in the Endpoint data model. Deprecated because the detection need rework and would need to work base on powershell logs.
