PE module

The PE module allows you to create more fine-grained rules for PE files by using attributes and features of the PE file format. This module exposes most of the fields present in a PE header and provides functions which can be used to write more expressive and targeted rules. Let's see some examples:

import "pe"

rule single_section
{
    condition:
        pe.number_of_sections == 1
}

rule control_panel_applet
{
    condition:
        pe.exports("CPlApplet")
}

rule is_dll
{
    condition:
        pe.characteristics & pe.DLL
}
