Command and Control (C&C)

CobalStrike: Cobalt Strike gives you a post-exploitation agent and covert channels to emulate a quiet long-term embedded actor in your customer’s network. Malleable C2 lets you change your network indicators to look like different malware each time. These tools complement Cobalt Strike’s solid social engineering process, its robust collaboration capability, and unique reports designed to aid blue team training.

Covenant: Covenant is a .NET command and control framework that aims to highlight the attack surface of .NET, make the use of offensive .NET tradecraft easier, and serve as a collaborative command and control platform for red teamers.

Empire: Empire 3 is a post-exploitation framework that includes a pure-PowerShell Windows agent, and compatibility with Python 3.x Linux/OS X agents. It is the merger of the previous PowerShell Empire and Python EmPyre projects. The framework offers cryptologically-secure communications and flexible architecture.

SILENTTRINITY: SILENTTRINITY is modern, asynchronous, multiplayer & multiserver C2/post-exploitation framework powered by Python 3 and .NETs DLR. It's the culmination of an extensive amount of research into using embedded third-party .NET scripting languages to dynamically call .NET API's, a technique the author coined as BYOI (Bring Your Own Interpreter).

koadic: Koadic, or COM Command & Control, is a Windows post-exploitation rootkit similar to other penetration testing tools such as Meterpreter and Powershell Empire. The major difference is that Koadic does most of its operations using Windows Script Host (a.k.a. JScript/VBScript), with compatibility in the core to support a default installation of Windows 2000 with no service packs (and potentially even versions of NT4) all the way through Windows 10.

merlin: Merlin is a cross-platform post-exploitation HTTP/2 Command & Control server and agent written in golang.
