Lab41/cyphercat

Cyphercat is an early and academically significant project from Lab41 (In-Q-Tel), but it is effectively a 'legacy' repository in the fast-moving field of AI security. With an age of nearly 8 years and zero recent velocity, the codebase likely targets deprecated versions of TensorFlow and PyTorch, making it difficult to use with modern transformer-based architectures or LLMs. While its 102 stars and 39 forks indicate it once held real interest for researchers, it has been largely superseded by more robust, actively maintained libraries like IBM's Adversarial Robustness Toolbox (ART), CleverHans, and Microsoft's Counterfit. Frontier labs and major cloud providers (AWS, Azure, Google) have already integrated privacy-auditing and red-teaming capabilities into their core platforms, rendering standalone, unmaintained tools like this obsolete for production environments. Its primary value today is as a historical reference for the implementation of membership inference logic.
