description: This search can help the detection of compromised accounts or internal users sending malicious documents via GSuite file sharing.
search: 'sourcetype="gsuite:drive:json" parameters.target_user=* name=change_user_access | spath "parameters.owner" | search "parameters.owner"="*" | stats count by src_ip parameters.owner parameters.target_user parameters.doc_type parameters.doc_title | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)`
| `gdrive_suspicious_file_sharing_filter`'
how_to_implement: To successfully implement this search, you need to be ingesting
logs related to gsuite (gsuite:drive:json) having the file sharing metadata like file type, source owner, destination target user, description, etc.
known_false_positives: This search will also produce normal activity statistics. Fields such as parameters.doc_type and parameters.doc_title may give away
phishing intent.
