Agentic Security是一款针对LLM模型的模糊测试与安全检测工具,该工具可以帮助广大研究人员针对任意LLM执行全面的安全分析与测试。
请注意 Agentic Security 是作为安全扫描工具设计的,而不是万无一失的解决方案。它无法保证完全防御所有可能的威胁。
1、可定制的规则集;
2、基于代理的测试;
3、针对任何 LLM 进行全面模糊测试;
4、LLM API 集成和压力测试;
5、整合了多种模糊测试和安全检测技术;

由于该工具基于Python 3开发,因此我们首先需要在本地设备上安装并配置好最新版本的Python 3环境。
广大研究人员可以直接使用下列命令将该项目源码克隆至本地:
git clone https://github.com/msoedov/agentic_security.git
然后切换到项目目录中,使用pip3命令和项目提供的requirements.txt安装该工具所需的其他依赖组件:
cd agentic_security pip3 install -r requirements
pip install agentic_security

python -m agentic_security # 或 agentic_security --help agentic_security --port=PORT --host=HOST
Agentic Security 使用纯文本 HTTP 参数,例如:
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 }
在扫描期间,将用实际攻击媒介替换<<PROMPT>>,插入的Bearer XXXXX需要包含您的应用程序凭据的标头值。
要添加自己的数据集,您可以放置一个或多个带有列的 csv 文件,这些数据将在启动prompt时加载

向 agentic_security.probe_data.REGISTRY 添加新元数据
{ "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", },
并实现加载器:
@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, }
当前示例之一使用对现有预加载提示数据进行采样,并应用变异来产生新的数据集
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, )
