WEASEL is a small in-memory implant using Python 3 with no dependencies. The beacon client sends a small amount of identifying information about its host to a DNS zone you control. WEASEL server can task clients to execute pre-baked or arbitrary commands.

PetaQ is a malware which is being developed in .NET Core/Framework to use websockets as Command & Control (C2) channels. It's designed to provide a Proof of Concept (PoC) websocket malware to the adversary simulation exercises (Red & Purple Team exercises).

C3 (Custom Command and Control) is a tool that allows Red Teams to rapidly develop and utilise esoteric command and control channels (C2). It's a framework that extends other red team tooling, such as the commercial Cobalt Strike (CS) product via ExternalC2, which is supported at release. It…

Havoc is a post-exploitation framework used for red team operations. It provides a centralized command and control system for managing remote agents through persistent network connections and customizable communication profiles. The framework focuses on security evasion and stealth, utilizing indirect syscall execution, return address spoofing, and hardware-breakpoint patching to bypass endpoint detection and response tools. It includes a payload generation workflow to create executable shellcode or DLLs for initial remote access. The system covers a broad range of operational capabilities,

dnscat2 is a DNS tunneling tool and covert command and control server that encapsulates encrypted traffic within DNS queries and responses. It functions as an encrypted DNS proxy designed to bypass network firewalls and establish communication paths when standard outbound ports are blocked. The project enables the creation of covert network channels by acting as an authoritative nameserver. It supports remote command execution through interactive shells and provides a mechanism for tunneling TCP network traffic to reach restricted remote hosts. The system includes capabilities for multiplexe

Apfell is a red teaming framework and command and control server designed for collaborative adversary simulation. It provides a centralized infrastructure to manage remote agents and distribute tasking across multiple operating systems using a message broker for real-time synchronization. The system functions as a distributed agent orchestrator, allowing teams to coordinate complex attack chains and synchronize container data. It features a multi-platform payload manager that enables the downloading and integration of custom agents and command profiles from remote repositories. The platform

EvilVM compiler for information security research tools. The project is built around a native code Forth compiler that is deployed as a position independent shellcode. It provides a platform for remote code execution, useful in information security contexts.
