Name:Windows RMM Tool Execution id:4afbd373-b769-4f82-8375-41e0153e46f9 version:2 date:None author:Raven Tait, Splunk status:production type:Anomaly Description:Detects process creation events of various remote access tools.
Remote management tools, when used for legitimate purposes, can help IT professionals and system administrators remotely access and manage computer systems.
However, threat actors may exploit these tools for malicious purposes. Data_source:
how_to_implement:The detection is based on data that originates from Endpoint Detection and Response (EDR) agents. These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives:Legitimate IT staff often use remote management tools for system maintenance and troubleshooting. Filter alerts to exclude trusted administrative activities.
