**Patterns**:所有检测规则均可在 `resk2/config/patterns.yaml` 中由用户编辑。无需更改代码。 - **Dependencies**:仅需 `pyyaml`。不需要 ML 框架。 - **Backwards compatible**:封装了原始的 `resk_llm` API。 - **resk-logits integration**:通过 [resk-logits](https://github.com/Resk-Security/resk-logits) 实现生成时的实时影子封禁。 ## 目录 -

LaTeX 宏、Markdown 代码块、零宽字符 - XML/HTML 标签注入、HTML 注释、代码块中的 base64 2. **Sentiment Saturation**(4 种模式):用情感或权威语言饱和内容,以统计偏差影响 agent 的合成 - 极度紧迫、权威凭证、道德命令 3. **Oversight & Critic Evasion**(6 种模式):将恶意指令包装在教育性、假设性或红队框架中,以绕过安全过滤器 - 学术目的、假设场景、红队测试、角色扮演 4. **Persona Hyperstition**(4 种模式):植入关于模型身份的叙述,该叙述通过检索重新进入,产生强化该标签的输出 - 身份重命名、叙述植入、检索重入、Persona 标记 ## 保护模块 ### Input Sanitizer ``` from resk2 import InputSanitizer sanitizer = InputSanitizer() clean = sanitizer.clean("Hello ") print(sanitizer.was_modified) # True ``` ### Output Validator ``` from resk2 import OutputValidator validator = OutputValidator() result = validator.validate("My email is user@example.com and password = secret123") print(f"Issues: {[i['type'] for i in result.issues]}") # ['email', 'credential'] ``` ### Canary Tokens ``` from resk2 import CanaryManager canary = CanaryManager() prompt = canary.insert("Process this confidential document") # ... 发送到 LLM ... result = canary.check("LLM response text") if result.has_leak: print(f"Leak detected!
