| Author: FalconForce | ||
| Version: '1.0' | ||
| Info: | | ||
| Gets all logon events from LogScale, filters out non-user logons, and creates a relationship between the computer and the user in Neo4j, | ||
| with the timestamp of the first logon event. | ||
| Active: true # Enable to run this action | ||
| Debug: false # Enable to see query results in the console | ||
| SourcePlatform: LogScale # Sentinel, Watchlist, Neo4j, CSV, MDE, Graph, Splunk | ||
| Query: | # Splunk index can be hardcoded or a variable set in the config.yml file | ||
| "@collect.source_name" = "windows_events" | ||
| | windows.EventID = 4624 | ||
| | windows.EventData.TargetUserSid = "S-1-5-21-*" | ||
| | windows.EventData.LogonType!=3 | ||
| | table([@timestamp,windows.EventData.TargetUserSid,windows.Computer]) | ||
| | rename(field=[[windows.EventData.TargetUserSid, TargetUserSid], [windows.Computer, Computer], [@timestamp, Timestamp]]) | ||
| Targets: # Targets are the platforms that this action will push to (CSV, Neo4j, Sentinel, Wachlist, Slack, Teams, Splunk, Markdown) | ||
| - Name: Neo4j | ||
| Enabled: true | ||
| Query: | | ||
| WITH toUpper($Computer) as Computer, toUpper($TargetUserSid) as TargetUserSid, $Timestamp as Timestamp | ||
