Inhale – Malware Analysis and Classification Tool

Inhale - Malware Analysis and Classification Tool

Inhale is a malware analysis and classification tool that is capable of automating and scaling many static analysis operations.

This is the beta release version, for testing purposes, feedback, and community development. Thanks to netspooky The developer of this amazing tool.


Inhale started as a series of small scripts that I used when collecting and analyzing a large amount of malware from diverse sources. There are plenty of frameworks and tools for doing similar work, but none of them really matched my workflow of quickly finding, classifying, and storing information about a large number of files. Some also require expensive API keys and other services that cost money.

I ended up turning these scripts into something that people can quickly set up and use, whether you run from a research server, a laptop, or a low-cost computer like a Raspberry Pi.

Install Inhale

This tool is built to run on Linux using Python3, ElasticSearch, radare2, yara, and binwalk. jq is also needed to pretty print output from the database. Here are some of the basic instructions to install.

Install Inhale Python3 Install requirements

sudo git clone
cd inhale
python3 -m pip install -r requirements.txt

After Inhale is installed, the following tools must all be installed in Inhale before you can use this tool properly.
Also in the video, you can see in detail how to do all this.

install Inhale linux

Installing ElasticSearch (Debian)

wget -qO - | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install elasticsearch
sudo service elasticsearch start

ElasticSearch Documentation
You can also install manually by following this documentation

Additionally, you can set up a full ELK stack for visualization and data analysis purposes. It is not necessary for using this tool.

Installing ElasticSearch (Debian)

Installing radare2

It’s important to install radare2 from the repo, and not your package manager. Package manager versions don’t come with all the bells and whistles required for Inhale.

git clone
cd radare2

radare2 install linux

Installing Yara

sudo apt-get install automake libtool make gcc
sudo wget
sudo tar xvzf v3.10.0.tar.gz
cd yara-3.10.0/
sudo ./
sudo ./configure
sudo make
sudo make install

If you get any errors about shared objects, try this to fix it.

sudo sh -c 'echo "/usr/local/lib" >> /etc/'
sudo ldconfig


Installing Yara

Installing binwalk

It’s most likely best to simply install binwalk from the repo.

sudo git clone
cd binwalk
sudo python3 install

More information on installing additional features for binwalk is located here.

Installing binwalk

Inhale Usage

Specify the file you are scraping by type:

-f infile    
-d directory
-u url
-r recursive url

Other options:

-t TAGS        Additional Tags
-b             Turn off binwalk signatures with this flag
-y YARARULES   Custom Yara Rules
-o OUTDIR      Store scraped files in specific output dir (default:./files/<date>/)
-i             Just print info, don't add files to database


Inhale help

python3 --help
└──╼ $python3 --help
usage: [-h] [-f INFILE] [-d DIRECTORY] [-r RDIRECTORY] [-u URLFILE]
                 [-t TAGS] [-b] [-y YARARULES] [-o OUTDIR] [-i]


optional arguments:
  -h, --help     show this help message and exit
  -f INFILE      File to add
  -d DIRECTORY   Directory to add
  -r RDIRECTORY  Remote directory (URL)
  -u URLFILE     File from a URL
  -t TAGS        Additional Tags
  -b             Turn off binwalk signatures with this flag
  -y YARARULES   Custom Yara Rules
  -o OUTDIR      Store scraped files in specific output dir (default:
  -i             Just print info, don't add files to database

View info on /bin/ls

Running will perform all of the analysis on a given file/directory/url and print it to your terminal.

View info on /bin/ls, but don’t add to the database

python3 -f /bin/ls -i 

python3 -f -bin-ls -i

Add directory ‘malwarez’ to database

python3 -d malwarez

Download this file and add to the database

python3 -u

Inhale Download everything in this remote directory, tag it all as “phishing”

python3 -r -t phishing

PROTIP: Use this Twitter hashtag search to find interesting open directories that possibly contain malware. Use it at your own risk.


You can pass your own Yara rules with -y, this is a huge work in progress and almost everything in “YaraRules” is from Shoutout @KevTheHermit

Querying the Database

Use to query (Soon to be a nice script) *something* | jq .

Data Model

The following is the current data model used for the elasticsearch database. Not every one of these will be used for every given file. Any r2_* tags are typically reserved for binaries of some sort.

filenameThe full path of the binary
file_extThe file extension
filesizeThe file size
filetypeFiletype based on magic value. Not as reliable as binwalk signatures.
md5The files MD5 hash
sha1The files SHA1 hash
sha256The files SHA256 hash
addedThe date the file was added
r2_archArchitecture of the binary file
r2_baddrThe binary’s base address
r2_binszThe size of the program code
r2_bitsArchitecture bits – 8/16/32/64 etc.
r2_canaryWhether or not stack canaries are enabled
r2_classBinary Class
r2_compiledThe date that the binary was compiled
r2_dbg_fileThe debug file of the binary
r2_intrpThe interpreter that the binary calls if dynamically linked
r2_langThe language of the source code
r2_lsymsWhether or not there are debug symbols
r2_machineThe machine type, usually means the CPU the binary is for
r2_osThe OS that the machine is supposed to run on
r2_picWhether or not there is Position Independent Code
r2_relocsWhether or not there are relocations
r2_rpathThe run-time search path – if applicable
r2_strippedWhether or not the binary is stripped
r2_subsysThe binary’s subsystem
r2_formatThe binary format
r2_iorwWhether ioctl calls are present
r2_typeThe binary type, whether or not it’s an executable, shared object etc.
yaraContains a list of yara matches
binwalkContains a list of binwalk signatures and their locations in the binary
tagsAny user defined tags passed with the -t flag.
urlThe origin url if a file was remotely downloaded
urlsAny URLs that have been pulled from the binary

Solutions to Issues

There are some known issues with this project (mainly to do with versions from package managers), and here I will track anything that has a solution for it.

ElasticSearch index field limit

If you get an error like this:

elasticsearch.exceptions.RequestError: RequestError(400, 'illegal_argument_exception', 'Limit of total fields [1000] in index [inhaled] has been exceeded')

You may have an older version of elasticSearch. You can upgrade, or you can increase the fields limit with this one liner.

curl -XPUT 'localhost:9200/inhaled/_settings' -H 'Content-Type: application/json' -d'{ "index" : { "mapping" : { "total_fields" : { "limit" : "100000" }}}}'
