Pftriage – Python Tool And Library To Help Analyze Files During Malware Triage And Analysis

pftriage is a tool to help analyze files during malware triage. It allows an analyst to quickly view and extract properties of a file to help during the triage process. The tool also has an analyze function which can detect common malicious indicators used by malware.DependenciespefilefilemagicNote: On Mac – Apple has implemented their own version of the file command. However, libmagic can be installed using homebrew$ brew install libmagicUsageusage: pftriage [options]Show information about a file for triage.positional arguments: file The file to triage.optional arguments: -h, –help show this help message and exit -i, –imports Display import tree -s, –sections Display overview of sections. For more detailed info pass the -v switch –removeoverlay Remove overlay data. –extractoverlay Extract overlay data. -r, –resources Display resource informations -D DUMP_OFFSET, –dump DUMP_OFFSET Dump data using the passed offset or ‘ALL’. Currently only works with resources. -a, –analyze Analyze the file. -v, –verbose Display version. -V, –version Print version and exit.SectionsDisplay Section information by using the -s or –sections switch. Additionally you can pass (-v) for a more verbose view of section details.To export a section pass –dump and the desired section Virtual Address.
