Identifies the creation of a Local Security Authority Server Service (LSASS) process clone via PssCaptureSnapShot where the parent process is the initial LSASS process instance. This may indicate an attempt to evade detection and dump LSASS memory for credential access.
Rule type: eql
Risk score: 73
Runs every: 5m
Maximum alerts per execution: 100
- Threat Detection
- Credential Access
Rule license: Elastic License v2
## Config This is meant to run only on datasources using Windows security event 4688 that captures the process clone creation. 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.
process where event.code:"4688" and process.executable : "?:\\Windows\\System32\\lsass.exe" and process.parent.executable : "?:\\Windows\\System32\\lsass.exe"
