This article describes how to use a custom Event Handler in FortiAnalyzer to detect activities related to exploits of Zoho ManageEngine ServiceDesk Plus, which is vulnerable to unauthenticated remote code execution. The vulnerability is assigned CVE-2021-44077.


What is included in
1. Zoho Exploit_event-handler.json
This event handler helps identify exploit attempts detected by FortiGate's AV, IPS and App Control detection. Also, it relies on FortiClient’s AV, Vulnerability and web filter detection as well as FortiSandbox detection. Logs triggering the event handler are generated from the FortiGate, FortiClient and FortiSandbox. Therefore, their corresponding AV signature should be kept up to date to prevent and log the exploits.


The custom Event Handler provided can be used in FortiAnalyzer 6.4+.



All screenshots provided below for illustration purposes are taken from FortiAnalyzer 6.4.4.
