 # Imprompter: Tricking LLM Agents into Improper Tool Use
 
-Code release in progress. Will be available shortly (expected by Oct 20).  Find more details about this work in our [paper](https://imprompter.ai/paper.pdf) and [website](https://imprompter.ai) for now!
+This is the codebase of `imprompter`. It provides essential components to reproduce and test the attack presented in the [paper](https://arxiv.org/abs/2410.14923). Video demos can be found on our [website](https://imprompter.ai). You may create your own attack on top of it as well.
+
+## Setup
+
+Setup python environment with `pip install .` or `pdm install` ([pdm](https://github.com/pdm-project/pdm)). We recommend using virtual environment (e.g. `conda` with `pdm venv`).
+
+For `GLM4-9b` and `Mistral-Nemo-12B` a 48GB VRAM GPU is required. For `Llama3.1-70b` 3x 80GB VRAM is required.
+
+## Configuration
+
+There are two config files that need potential attention before you run the algorithm
+- `./configs/model_path_config.json` defines the path of the huggingface model on your system. You most likely need to modify this accordingly.
+- `./configs/device_map_config.json` configures layer mapping for loading the models on multi-gpu. We show case our configuration for loading LLama-3.1-70B on 3x Nvidia A100 80G GPUs. You may need to adjust this accordingly for your computational environments.
+
+## Run Optimization
+
+Follow the example execution scripts e.g. `./scripts/T*.sh`. The explainations of each argument can be found in Section 4 of our [paper](https://arxiv.org/abs/2410.14923).
+
+The optimization program will generate results in `.pkl` files and logs in the `./results` folder. The pickle file updates every step during the execution and always stores the current top 100 adversarial prompts (with lowest loss). It is structured as a min heap, where the top of it is the prompt with the lowest loss. Each element of the heap is a tuple of `(<loss>, <adversarial prompt in string>, <optimization iteration>, <adversarial prompt in tokens>)`. You can always restart from an existing pickle file by adding `--start_from_file <path_to_pickle>` arguments to its original execution script.
+
+## Evaluation
+
+Evaluation is done through `evaluation.ipynb`. Follow the detailed instructions there to  generations against testing dataset, computation of metrics, etc. 
+
+
+One special case is the PII prec/recall metrics. They are computed standalone with `pii_metric.py`. Note that `--verbose` gives your full PII details of each conversation entry for debugging and `--web` should be added when the results are obtained from real products on the web. 
+
+Example usage (non web result i.e. local test):
+
+`python pii_metric.py --data_path datasets/testing/pii_conversations_rest25_gt.json --pred_path evaluations/local_evaluations/T11.json`
+
+Example usage (web result i.e. real product test):
+
+`python pii_metric.py --data_path datasets/testing/pii_conversations_rest25_gt.json --pred_path evaluations/product_evaluations/N6_lechat.json --web --verbose`
+
+## Browser Automation
+
+We use Selenium to automate the testing process on real products (Mistral LeChat and ChatGLM). We provide the code in `browser_automation` directory. Note we have only tested this on a desktop environment on Windows 10 and 11. It is supposed to work also on Linux/MacOS but not guaranteed. Might need some small tweaks.  
+
+Example usage:
+`python browser_automation/main.py --target chatglm --browser chrome --output_dir test --dataset datasets/pii_conversations_rest25_gt.json --prompt_pkl results/T12.pkl --prompt_idx 1`
+
+- `--target` specifies the product, right now we support `chatglm` and `mistral` two options. 
+- `--browser` defines the browser to be using, you should either use `chrome` or `edge`.  
+- `--dataset` points to the conversation dataset to test with
+- `--prompt_pkl` refers the pkl file to read prompt from and `--prompt_idx` defines the ordered index of the prompt to use from the pkl. Alternatively, one may define the prompt in `main.py` directly and do not provide these two options.  
+
+## Reproducibility
+
+We provide all the scripts (`./scripts`) and datasets (`./datasets`) to obtain the prompts (T1-T12) we present in the [paper](https://arxiv.org/abs/2410.14923). Moreover, we also provide the pkl result file (`./results`) for each of the prompt as long as we still keep a copy and the evaluation result of them (`./evaluations`) obtained through `evaluation.ipynb`. Note that for PII Exfiltration attack, the training and testing datasets contain real-world PII. Even though they are obtained from the public [WildChat](https://wildchat.allen.ai/) Dataset, we decide to not make them directly public for privacy concerns. We provide a single entry subset of these datasets at `./datasets/testing/pii_conversations_rest25_gt_example.json` for your reference. Please contact us to request the complete version of these two datasets. 
+
+## Disclosure and Impact
+
+We initiated disclosure to Mistral and ChatGLM team on Sep 9, 2024, and Sep 18, 2024, respectively. Mistral security team members responded promptly and acknowledged the vulnerability as a **medium-severity issue**. They fixed the data exfiltration by disabling markdown rendering of external images on Sep 13, 2024 (find the acknowledgement in [Mistral changelog](https://docs.mistral.ai/getting-started/changelog/)). We confirmed that the fix works. ChatGLM team responded to us on Oct 18, 2024 after multiple communication attempts through various channels and stated that they have begun working on it.
