Contributing

Once you have developed your payload, you are encouraged to contribute to this repository by submitting a Pull Request. Reviewed and Approved pull requests will add your payload to this repository, where they may be publically available.

Please adhere to the following best practices and style guide when submitting a payload.

Naming Conventions

Payloads should be submitted to the most approporiate category directory. These include credentials, exfiltration, phishing, prank, recon, etc.

Each payload should have a unique, descriptive directory and filename, e.g., WIN_powershell_SMB_exfiltration.txt

The directory name for the payload should match the payload file name.

If the payload is OS specific (I.e., a Windows powershell attack), the filename should be prefixed with that OS. Prefixes include:

• WIN_ for Windows
• MAC_ for MacOS
• LINUX_ for all Linux flavors
• MULTI_ for multi-OS payloads

If the payload is OS agnostic (I.e., it substitutes text or otherwise make no interaction with the target OS), the filename should not include an OS prefix.

If multiple individual OS specific payloads are included, the directory name should be prefixed with MULTI_ while each payload file name therein should be prefixed with the specific OS.

Please give your payload a unique and descriptive name. Do not use spaces in payload names. Each payload should be submit into its own directory, with - or _ used in place of spaces, to one of the categories such as exfiltration, phishing, remote_access or recon. Do not create your own category.

Comments

Each payload should begin with a comment block containing at least:

Title: <name of the payload>
Description: <Brief description of what the payload does>
Author: <name (I.e, twitter/Hak5 forum handle)>

Optionally, authors are encouraged to include these additional parameters:

# Version: <Number (e.g., 1.0)>
# Props: <people who inspired/helped the payload development>
# Target: <specific OS/version, (e.g., Windows XP SP3)

Configuration Options

Payloads should be written in a flexible way such that modifications may be made by changing variables. Variables should use descriptive names where possible. All variables for a payload should be specified, as practical, just below the comment block at the top of the payload file.

For true or false variables, use VARIABLE=1 for true and VARIABLE=0 for false.

In the case that the payload is Cloud C2 aware (e.g., for optional exfiltration or notification), the CLOUDC2=1 variable should be set.

CMD_OBFUSCATION=1
CLOUDC2=1

Payload Documentation

If a payload requires additional documentation for use, such as requiring special dependency installation or use of the LED, it should be documented in the code block. In the case of LED for status, use the following:

# LED ERROR: Dependency not found
# LED SETUP: Starting services
# LED ATTACK: Performing attack
# LED SPECIAL: Exfiltrating loot
# LED CLEANUP: Removing temp files
# LED FINISH: Attack complete

If custom color/patterns are used instead of standard LED states, designate these status indications accordingly.

Payloads may optionally include a readme.md file for documentation.
