Open Source C Frameworks

It uses a range of methods to evade EDR and AV while allowing the operator to continue using tooling and tradecraft they are familiar with. Its powered by Python 3.8 and C, and uses Donut for payload generation. By using Donut along with the process injection capabilities of SHAD0W, it provides the operator the ability to execute .NET assemblies, DLLs, EXEs, JS, VBS or XSLs fully inside the memory. Dynamically resolved syscalls are heavily used to avoid userland API hooking, anti-DLL injection to make it harder for EDR to load code into the beacons, and official Microsoft mitigation methods to protect spawn processes. Runs fully inside of Docker allowing cross-platform usage. SHAD0W is a modular C2 framework designed to successfully operate on mature environments. All traffic between beacons and the C2 are encrypted and transmitted over HTTPS.

Cross-platform high-level cryptographic library. Themis helps to build simple and complex cryptographic features easily, quickly, and securely. It’s a perfect fit for multi-platform apps. Themis hides cryptographic details and eliminates popular mistakes. Themis provides ready-made building blocks (“cryptosystems”) for secure data storage, message exchange, socket connections, and authentication. Secure Cell is a multi-mode cryptographic container suitable for storing anything from encrypted files to database records. Use Secure Cell to encrypt data at rest. Secure Cell is built around AES-256-GCM, and AES-256-CTR. Secure Message is a simple encrypted messaging solution for the widest scope of applications. Use Secure Message to send encrypted and signed data from one user to another, from client to server, to prevent MITM attacks and avoid single secret leakage. Based on ECC + ECDSA / RSA + PSS + PKCS#7.
