Enabling or disabling dropper detection

Use the CLI commands to enable or disable the dropper detection component, which provides another type of static analysis on the Email Security - Server appliance. This component allows the Email Security - Server appliance to identify malicious files that might have installed additional types of malware on your system. A dropper is not associated with any file extensions, and it is often part of a spearphishing attempt. The Email Security - Server appliance sends the dropper files that matched the first ten MD5 checksums to the Dynamic Threat Intelligence (DTI) Cloud for further analysis. When the dropper detection component is disabled, the Email Security - Server appliance does not send the dropper files to the DTI Cloud.

After you have configured the appliance to detect dropper files using the CLI, you can view the analysis of the results on the eAlerts > Alerts page in the Web UI.

Note

You can enable or disable dropper detection only using the CLI. This component is enabled by default.

Because the Intelligent Virtual Execution - Server compute node performs static analysis on submitted malware samples, the output fields for each static analysis tool are not displayed for the show static-analysis config command on the sensor.
