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 ThinkPHP Remote Code Execution Vulnerability. A report is also provided to gain historical visibility into logs.

Scope This article contains the files necessary to load an event handler and report into 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.
Solution
