Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

The Changelog starts with v0.4.1, because we did not keep one before that, and simply didn't have the time to go back and retroactively create one.

[Unreleased]

Fixed

  • Fixed shlex.join use with non-str type objects (e.g. RemotePath)
  • Fixed set command use with incorrect keys (e.g. set invalid value)

Added

[0.5.2] - 2021-12-31

Changed

  • Fixed --version switch.
  • Fixed readme typos.

Added

  • Read the Docs Configuration File

[0.5.0] - 2021-11-28

This is a major release mainly due to the name change, and PyPI package addition. The package has been renamed to pwncat-cs and the default entrypoint has also been renamed to pwncat-cs. These changes were made in an effort to deconflict with Cytopia pwncat. Beyond that, some new features were added as seen in the release notes below.

I've tried to update all references to the old pwncat entrypoint, but may have missed some throughout the documentation or code. Please open an issue if you notice any old references to the previous name.

It's worth noting that the internal module name is still pwncat, as Cytopia does not implement an importable package (only a command line entrypoint). I may change this name in the future, but for now it doesn't cause any issues and would require a major refactor so I'm going to leave it.

Changed

  • Moved dependency management and building to Poetry.
  • Changed package name to pwncat-cs in order to not conflict w/ cytopia/pwncat.

Added

  • Added ssl-bind and ssl-connect channel protocols for encrypted shells
  • Added ncat-style ssl arguments to entrypoint and connect command
  • Added query-string arguments to connection strings for both the entrypoint and the connect command.
  • Added Enumeration States to allow session-bound enumerations
  • Added PyPi publishing to GitHub publish workflow.
  • Added licensing for pwncat (MIT)
  • Added background listener API and commands (#43)
  • Added Windows privilege escalation via BadPotato plugin (#106)

Removed

  • Removed setup.py and requirements.txt
