πŸ€” What is this?

Imagine this: You come across some mysterious text πŸ§™β€β™‚οΈ 0x52908400098527886E0F7030069857D2E4169EE7 or dQw4w9WgXcQ and you wonder what it is. What do you do?

Well, with what all you have to do is ask what "0x52908400098527886E0F7030069857D2E4169EE7" and what will tell you!

what's job is to identify what something is. Whether it be a file or text! Or even the hex of a file! What about text within files? We have that too! what is recursive, it will identify everything in text and more!


πŸ”¨ Using pip

$ pip3 install pywhat


# installs optional dependencies that may improve the speed
$ pip3 install pywhat[optimize] 

πŸ”¨ On Mac?

$ brew install pywhat

Or for our MacPorts fans:

$ sudo port install pywhat

βš™ Use Cases

🦠 Wannacry

You come across a new piece of malware called WantToCry. You think back to Wannacry and remember it was stopped because a researcher found a kill-switch in the code.

When a domain, hardcoded into Wannacry, was registered the virus would stop.

You use What to identify all the domains in the malware, and use a domain registrar API to register all the domains.

🦈 Faster Analysis of Pcap files

Say you have a .pcap file from a network attack. What can identify this and quickly find you:

  • All URLs
  • Emails
  • Phone numbers
  • Credit card numbers
  • Cryptocurrency addresses
  • Social Security Numbers
  • and much more.

With what, you can identify the important things in the pcap in seconds, not minutes.

🐞 Bug Bounties

You can use PyWhat to scan for things that'll make you money via bug bounties like:

  • API Keys
  • Webhooks
  • Credentials
  • and more

Run PyWhat with:

pywhat --include "Bug Bounty" TEXT

To do this.

Here are some examples πŸ‘‡

πŸ™ GitHub Repository API Key Leaks

  1. Download all GitHub repositories of an organisation
  2. Search for anything that you can submit as a bounty, like API keys
# Download all repositories
GHUSER=CHANGEME; curl "https://api.github.com/users/$GHUSER/repos?per_page=1000" | grep -o 'git@[^"]*' | xargs -L1 git clone

# Will print when it finds things.
# Loops over all files in current directory.
find . -type f -execdir pywhat --include 'Bug Bounty' {} \;

πŸ•· Scan all web pages for bounties

# Recursively download all web pages of a site
wget -r -np -k https://skerritt.blog

# Will print when it finds things.
# Loops over all files in current directory.
find . -type f -execdir pywhat --include 'Bug Bounty' {} \;

PS: We support more filters than just bug bounties! Run pywhat --tags

🌌 Other Features

Anytime you have a file and you want to find structured data in it that's useful, What is for you.

Or if you come across some piece of text and you don't know what it is, What will tell you.

πŸ“ File & Directory Handling

File Opening You can pass in a file path by what 'this/is/a/file/path'. What is smart enough to figure out it's a file!

What about a whole directory? What can handle that too! It will recursively search for files and output everything you need!

πŸ” Filtering your output

Sometimes, you only care about seeing things which are related to AWS. Or bug bounties, or cryptocurrencies!

You can filter output by using what --rarity 0.2:0.8 --include Identifiers,URL https://skerritt.blog. Use what --help to get more information.

To see all filters, run pywhat --tags! You can also combine them, for example to see all cryptocurrency wallets minus Ripple you can do:

pywhat --include "Cryptocurrency Wallet" --exclude "Ripple Wallet" 1KFHE7w8BhaENAswwryaoccDb6qcT6DbYY

πŸ‘½ Sorting, Exporting, and more!

Sorting You can sort the output by using what -k rarity --reverse TEXT. Use what --help to get more information.

Exporting You can export to json using what --json and results can be sent directly to a file using what --json > file.json.

Boundaryless mode What has a special mode to match identifiable information within strings. By default, it is enabled in CLI but disabled in API. Use what --help or refer to API Documentation for more information.
