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 Iran-linked Cyber Attacks. A report is also provided to gain historical visibility into the logs.

 

Note that this article provides alpha files, which are automatically generated. The article will be continually updated as more information becomes available.
Scope

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

 

For more information about this attack, see the following FortiGuard Outbreak Alert:
