Litterbox

Litterbox is a web-based platform designed to support the development and testing of malware payloads in a controlled environment. It serves as a sandbox for red teamers to validate evasion techniques, assess detection signatures, and analyze implant behavior before deploying them in real-world scenarios. The platform offers automated analysis through an intuitive interface, monitoring process behavior and generating comprehensive runtime reports. This ensures that payloads function as intended before execution in target environments.

Key features of Litterbox include behavioral monitoring, memory region inspection, process hollowing detection, injection technique analysis, and sleep pattern monitoring. It also supports file identification with multiple hashing algorithms, Shannon entropy calculation for encryption detection, and advanced file type detection. For Windows executables, it provides PE file type detection, machine architecture identification, and compilation timestamp analysis. Additionally, it offers macro detection and VBA code analysis for Microsoft Office documents.

By using Litterbox, users can refine their tradecraft without leaving traces on production detection systems. The platform's automated analysis and reporting capabilities make it a valuable tool for those involved in malware development and testing, providing a secure and efficient way to perfect payloads before deployment.
