## Config Named Pipe Creation Events need to be enabled within the Sysmon configuration by including the following settings: `condition equal "contains" and keyword equal "pipe"` 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 8.2, so you will need to add a custom pipeline to populate `event.ingested` to @timestamp for this rule to work.
file where event.action : "Pipe Created*" and /* normal sysmon named pipe creation events truncate the pipe keyword */ file.name : "\\*\\Pipe\\*"
