Execution of COM object via Xwizard

Windows Component Object Model (COM) is an inter-process communication (IPC) component of the native Windows application programming interface (API) that enables interaction between software objects or executable code. Xwizard can be used to run a COM object created in registry to evade defensive counter measures.

Setup

edit

Setup

If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2, events will not define event.ingested and default fallback for EQL rules was not added until version 8.2. Hence for this rule to work effectively, users will need to add a custom ingest pipeline to populate event.ingested to @timestamp. For more details on adding a custom ingest pipeline refer - https://www.elastic.co/guide/en/fleet/current/data-streams-pipeline-tutorial.html

process where host.os.type == "windows" and event.type == "start" and
 (process.name : "xwizard.exe" or ?process.pe.original_file_name : "xwizard.exe") and
 (
   (process.args : "RunWizard" and process.args : "{*}") or
   (process.executable != null and
     not process.executable : ("C:\\Windows\\SysWOW64\\xwizard.exe", "C:\\Windows\\System32\\xwizard.exe")
