YaraRET

Introduction

YaraRET is a carving tool based in Radare2 and Yara and written in Go. It provides 58 magic number's yara rules for detecting 58 types of files.

This tool is based on the idea of a first stage detecting files using its magic numbers and a second stage, selecting or discarding those detected files using Yara, IoC or its entropy value. After that, it is able to generate the hash, the ssdeep (and check it over anothers). Also provides an integration with VirusTotal.

In order to deal with forensics cases based on weak clues, YaraRET provides different modes for raw disk handling.

Install

For a compiled bin, you can download last release from Github.

Also, you can download git repo and build it.

Dependencies

Yara Radare2

github.com/abiosoft/ishell
github.com/docopt/docopt-go
github.com/glaslos/ssdeep

Usage

YaraRET provides diferent modes for handling different forensics cases.

If you are interested in get a file from a yara rule, you can execute the following command:

$  ./yaraRET yara myYaraRule rawdisk myRaw maxsize 3000 

If you are interested in get a file from an IoC like a domain or hash from any kind of file like STIX or txt

$ ./yaraRET ioc ./myIOC.stix rawdisk myRaw maxsize 3000

For a complex analysis, YaraRET provides a shell mode which allows an analysis at the tool's opening

$  ./yaraRET rawdisk myRaw shell 


>> start all
>> set pe
>> show -
