Simple BoN Jailbreaking for Ollama

This project is based on the references linked below. Since the original source code from the paper is difficult to use, I created a simple Python program for local testing.

• https://github.com/jplhughes/bon-jailbreaking

The main source file is bon.py, which borrows code from bon-jailbreaking, including functions such as FALSE_POSITIVE_PHRASES, apply_word_scrambling, apply_random_capitalization, and apply_ascii_noising for text augmentation.

To determine whether a response is harmful, this program uses the OpenAI moderation API.

In bon.py, the model llama3.2 is hardcoded for testing purposes. You can replace it with any Ollama-supported model.

For an example of test result, see candidate.txt.
