Abstract
Mechanisms, which can include systems, method, and media, for protecting network devices from malicious rich text format (RTF) files are provided, the mechanisms comprising: intercepting an RTF file destined for a network device; parsing the RTF file to identify a plurality of objects in the RTF file; checking a first object of the plurality of objects for a first heuristic; based upon an outcome of the checking of the first object for the first heuristic, increasing a cumulative weight by a first weight value; comparing the cumulative weight against at least one threshold to classify the RTF file; and based on the classification of the RTF file, taking a protective action on the RTF file.
