ChopShop is a MITRE-developed framework designed to assist security analysts in creating and executing pynids-based decoders and detectors for identifying Advanced Persistent Threat (APT) tradecraft. The framework relies on libnids/pynids for its core functionality and provides analysts with tools to analyze network traffic and detect sophisticated attack patterns. ChopShop enables the development of custom network protocol decoders that can identify specific APT techniques and tactics within network communications. The tool is currently maintained in perpetual beta status, indicating ongoing development and refinement. Documentation is available through ReadTheDocs to support users in implementation and usage. There are known compatibility issues with certain Ubuntu distributions where the apt-installed version of pynids may cause ImportError exceptions. This affects Ubuntu versions 11.10 and 12.04, with a recommended workaround involving compiling pynids from source code available through the MITRECND GitHub repository.
