The SPL above uses the following Macros:

:information_source: registry_keys_used_for_persistence_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

  • Registry.registry_path
  • Registry.dest
  • Registry.user

How To Implement

To successfully implement this search, you must be ingesting data that records registry activity from your hosts to populate the endpoint data model in the registry node. This is typically populated via endpoint detection-and-response product, such as Carbon Black or endpoint data sources, such as Sysmon. The data used for this search is typically generated via logs that report reads and writes to the registry.

Known False Positives

There are many legitimate applications that must execute on system startup and will use these registry keys to accomplish that task.

Associated Analytic Story


Risk Score Impact Confidence Message
76.0 80 95 A registry activity in $registry_path$ related to persistence in host $dest$

:information_source: The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
