Process activity around time of incident
It's sometimes beneficial to analyze processes that are not part of the same incident. Querying the process activity around the time of an incident can aid in discovering other malicious activity or depth of damage.
Required Tables
- process_events
Input Fields
Each Sophos Linux Sensor (SLS) Alert is assigned an Incident_id representing that the Alert is part of an incident. This incident ID should replace the <INCIDENT ID FROM SLS ALERT>
text in the provided query.
Returned Fields
Field | Description |
---|---|
process_events.* | Full process events from 10 minutes before and after and event |
Query
SELECT *
FROM process_events
LEFT JOIN
(SELECT MAX(unix_nano_timestamp) AS max_incident_time,
MIN(unix_nano_timestamp) AS min_incident_time,
process_uuid AS id
FROM process_events
WHERE incident_id='<INCIDENT ID FROM SLS ALERT>'
GROUP BY process_uuid) AS incident ON process_events.process_uuid=incident.id
WHERE process_uuid=incident.id
AND unix_nano_timestamp < incident.max_incident_time + (10*60*1e9)
AND unix_nano_timestamp > incident.min_incident_time - (10*60*1e9)
