description: |-
    Detects the malicious java plugin execution used by metasploit for Atlassian Confluence exploitation.
    This usually leads to the download of meterpreter giving the actor full control over the Confluence server.

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: Some legitimate penetration testing tools or authorized security assessments may trigger this detection. Verify activity with your security team before taking action.
