Description This article describes how to use a custom event handler in FortiAnalyzer to raise alerts for incident response related to attacks that attempt to leverage the Progress Telerik UI Attack. A report is also provided to gain historical visibility into your logs.
Scope

This article contains the files necessary to load an event handler and report into your FortiAnalyzer for either a Fabric ADOM or a FortiGate ADOM. The Fabric report and event handler leverage logs from other Fortinet products that can be used to detect the attack in addition to FortiGate logs.
