Known False Positives

This is a hunting search and requires an operator to search for specific indicators of Server Side Request Forgery attack against /data/ui/views. It is not possible to grab display the payloads of such requests, so this search provides users, ip addresses, requests, files, and queries that may indicate malicious intent. There will be false positives.
