McAfee VirusScan On-Demand scan must be configured to decode MIME encoded files.


Overview

Finding ID Version Rule ID IA Controls Severity
V-6612 DTAM053 SV-56404r1_rule Medium
Description
Multipurpose Internet Mail Extensions (MIME) encoded files can be crafted to hide a malicious payload. When the MIME encoded file is presented to software that decodes the MIME encoded files, such as an email client, the malware is released. Scanning these files as part of the regularly scheduled scans tasks will mitigate this risk.
