This package contains a proxy aware C2 framework used to aid penetration testers with red teaming, post-exploitation and lateral movement. PoshC2 is primarily written in Python3 and follows a modular format to enable users to add their own modules and tools, allowing an extendible and flexible C2 framework. Out-of-the-box PoshC2 comes PowerShell/C# and Python3 implants with payloads written in PowerShell v2 and v4, C++ and C# source code, a variety of executables, DLLs and raw shellcode in addition to a Python3 payload. These enable C2 functionality on a wide range of devices and operating systems, including Windows, *nix and OSX. Other notable features of PoshC2 include: - Consistent and Cross-Platform support using Docker. - Highly configurable payloads, including default beacon times, jitter, kill dates, user agents and more. - A large number of payloads generated out-of-the-box which are frequently updated and maintained to bypass common Anti-Virus products. - Auto-generated Apache Rewrite rules for use in a C2 proxy, protecting your C2 infrastructure and maintaining good operational security. - A modular format allowing users to create or edit C#, PowerShell or Python3 modules which can be run in-memory by the Implants. - Notifications on receiving a successful Implant, such as via text message or Pushover. - A comprehensive and maintained contextual help and an intelligent prompt with contextual auto-completion, history and suggestions. - Fully encrypted communications, protecting the confidentiality and integrity of the C2 traffic even when communicating over HTTP. - Client/Server format allowing multiple team members to utilise a single C2 server. - Extensive logging. Every action and response is timestamped and stored in a database with all relevant information such as user, host, implant number etc. In addition to this the C2 server output is directly logged to a separate file. - PowerShell-less implants that do not use System.Management.Automation.dll using C# or Python. - A free and open-source SOCKS Proxy by integrating with SharpSocks
