Features

Agentic Security equips you with powerful tools to safeguard LLMs against emerging threats. Here's what you can do:

• Multimodal Attacks 🖼️🎙️ Probe vulnerabilities across text, images, and audio inputs to ensure your LLM is robust against diverse threats.

• Multi-Step Jailbreaks 🌀 Simulate sophisticated, iterative attack sequences to uncover weaknesses in LLM safety mechanisms.

• Comprehensive Fuzzing 🧪 Stress-test any LLM with randomized inputs to identify edge cases and unexpected behaviors.

• API Integration & Stress Testing 🌐 Seamlessly connect to LLM APIs and push their limits with high-volume, real-world attack scenarios.

• RL-Based Attacks 📡 Leverage reinforcement learning to craft adaptive, intelligent probes that evolve with your model’s defenses.

Why It Matters: These features help developers, researchers, and security teams proactively identify and mitigate risks in AI systems, ensuring safer and more reliable deployments.

📦 Installation

To get started with Agentic Security, simply install the package using pip:

pip install agentic_security

MCP client example

Agentic Security includes an MCP stdio server in agentic_security.mcp.main. To list the available MCP tools from a local checkout:

python examples/mcp_client_usage.py

To call HTTP-backed tools, run the Agentic Security app first, then point the MCP server at it:

agentic_security --host 127.0.0.1 --port 8718
python examples/mcp_client_usage.py --agentic-security-url http://127.0.0.1:8718 --call get_spec_templates

See docs/mcp_client_usage.md for the full walkthrough.

LLM kwargs

Agentic Security uses plain text HTTP spec like:

POST https://api.openai.com/v1/chat/completions
Authorization: Bearer sk-xxxxxxxxx
Content-Type: application/json

{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "<<PROMPT>>"}],
     "temperature": 0.7
}

Where <<PROMPT>> will be replaced with the actual attack vector during the scan, insert the Bearer XXXXX header value with your app credentials.

Adding LLM integration templates

TBD

....

Adding own dataset

To add your own dataset you can place one or multiples csv files with prompt column, this data will be loaded on agentic_security startup

2024-04-13 13:21:31.157 | INFO     | agentic_security.probe_data.data:load_local_csv:273 - Found 1 CSV files
2024-04-13 13:21:31.157 | INFO     | agentic_security.probe_data.data:load_local_csv:274 - CSV files: ['prompts.csv']

Extending dataset collections

1. Add new metadata to agentic_security.probe_data.REGISTRY

    {
        "dataset_name": "markush1/LLM-Jailbreak-Classifier",
        "num_prompts": 1119,
        "tokens": 19758,
        "approx_cost": 0.0,
        "source": "Hugging Face Datasets",
        "selected": True,
        "dynamic": False,
        "url": "https://huggingface.co/markush1/LLM-Jailbreak-Classifier",
    },

and implement loader into

@dataclass
class ProbeDataset:
    dataset_name: str
    metadata: dict
    prompts: list[str]
    tokens: int
    approx_cost: float

    def metadata_summary(self):
        return {
            "dataset_name": self.dataset_name,
            "num_prompts": len(self.prompts),
            "tokens": self.tokens,
            "approx_cost": self.approx_cost,
        }

Dynamic datasets with mutations

One of the current examples uses sampling for the existing preloaded prompt data and applying mutations yielding a new dataset

class Stenography:
    fn_library = {
        "rot5": stenography_fn.rot5,
        "rot13": stenography_fn.rot13,
        "base64": stenography_fn.base64_encode,
        "mirror": stenography_fn.mirror_words,
        "random_case": stenography_fn.randomize_letter_case,
        "scramble_words": stenography_fn.scramble_words,
        "noise_characters": stenography_fn.insert_noise_characters,
        "substitute_with_ascii": stenography_fn.substitute_with_ascii,
        "remove_vowels": stenography_fn.remove_vowels,
        "zigzag_obfuscation": stenography_fn.zigzag_obfuscation,
    }

    def __init__(self, prompt_groups: [ProbeDataset]):
        self.prompt_groups = prompt_groups

    def apply(self):
        for prompt_group in self.prompt_groups:

            size = len(prompt_group.prompts)
            for name, fn in self.fn_library.items():
                logger.info(f"Applying {name} to {prompt_group.dataset_name}")
                selected_prompts = random.sample(prompt_group.prompts, int(size * 0.25))
                prompts = [
                    f"Follow the instructions in {name}: {fn(p)}"
                    for p in selected_prompts
                ]
                yield ProbeDataset(
                    dataset_name=f"stenography.{name}({prompt_group.dataset_name})",
                    metadata={},
                    prompts=prompts,
                    tokens=count_words_in_list(prompts),
                    approx_cost=0.0,
                )

Probe endpoint

In the example of custom integration, we use /v1/self-probe for the sake of integration testing.

POST https://agentic_security-preview.vercel.app/v1/self-probe
Authorization: Bearer XXXXX
Content-Type: application/json

{
    "prompt": "<<PROMPT>>"
}

This endpoint randomly mimics the refusal of a fake LLM.

@app.post("/v1/self-probe")
def self_probe(probe: Probe):
    refuse = random.random() < 0.2
    message = random.choice(REFUSAL_MARKS) if refuse else "This is a test!"
    message = probe.prompt + " " + message
    return {
        "id": "chatcmpl-abc123",
        "object": "chat.completion",
        "created": 1677858242,
        "model": "gpt-3.5-turbo-0613",
        "usage": {"prompt_tokens": 13, "completion_tokens": 7, "total_tokens": 20},
        "choices": [
            {
                "message": {"role": "assistant", "content": message},
                "logprobs": None,
                "finish_reason": "stop",
                "index": 0,
            }
        ],
    }

Image Modality

To probe the image modality, you can use the following HTTP request:

POST http://0.0.0.0:9094/v1/self-probe-image
Authorization: Bearer XXXXX
Content-Type: application/json

[
    {
        "role": "user",
        "content": [
            {
                "type": "text",
                "text": "What is in this image?"
            },
            {
                "type": "image_url",
                "image_url": {
                    "url": "data:image/jpeg;base64,<<BASE64_IMAGE>>"
                }
            }
        ]
    }
]

Replace XXXXX with your actual API key and <<BASE64_IMAGE>> is the image variable.

Audio Modality

To probe the audio modality, you can use the following HTTP request:

POST http://0.0.0.0:9094/v1/self-probe-file
Authorization: Bearer $GROQ_API_KEY
Content-Type: multipart/form-data

{
    "file": "@./sample_audio.m4a",
    "model": "whisper-large-v3"
}

Replace $GROQ_API_KEY with your actual API key and ensure that the file parameter points to the correct audio file path.
