This article describes how to use a custom Event Handler in FortiAnalyzer to detect activities related to the Emotet malware, which has been detected in spam campaigns recently.
What is included in Fortinet_SOC-Emotet-Malware-Detection.zip?
1. Emotet Malware_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 and Report provided can be used in FortiAnalyzer 6.4+.
All screenshots provided below for illustration purposes are taken from FortiAnalyzer 6.4.4.
1) Download the Fortinet_SOC-Emotet-Malware-Detection.zip file (contains 1 file)
