DeepSeek Harness 的提示注入、越狱和秘密泄露防御:基于 Aho-Corasick 检测,支持允许/询问/阻止拦截及脱敏审计事件

Project Overview项目介绍

dsh-defend is a native security plugin built exclusively for DeepSeek Harness (DSH). It provides multi-layered protection against prompt injection, malicious jailbreak attempts, and accidental sensitive information leaks. To install it, you can run dsh plugin --profile web add dsh-defend for the stable npm release, or dsh plugin --profile web add "github:PerryLink/dsh-defend#main" for the latest development version from the main branch. It is compatible with DSH versions from 0.1.2-rc.1 up to before 0.2.0, and it is a pure JavaScript package that runs on all platforms without requiring native code or external network access.

The plugin scans content at three key interception points before the content reaches the DSH agent or is passed to a tool for execution. The default policy is to ask for user approval for most risky cases and automatically block requests that contain critical sensitive secrets. Every detection leaves an audit trail that records the rule ID, severity, and decision, and it never short-circuits downstream policy plugins, so other security plugins can run their own checks after it completes. It is designed for any DSH user who wants to harden their agent against malicious inputs and accidental data leaks.

dsh-defend requires Node.js version 22.19.0 or newer, or any major version 24 and above, to run properly on your host machine. It is released under the open-source Apache 2.0 license, and all detection rules are ported from four upstream Apache 2.0-licensed projects, with full third-party attribution documented in the THIRD_PARTY_NOTICES.md file. After you first install the plugin, you will need to restart your DSH instance for it to take effect, and you can verify the installation by running a simple dump-config command to check that the plugin entry exists in your active configuration.

dsh-defend 是专为 DeepSeek Harness(DSH)开发的原生安全插件,核心功能是针对提示注入、恶意越狱绕过和敏感信息泄露提供多层防护。它可以通过 DSH 内置插件命令直接从 npm 或 GitHub 仓库安装,适配 DSH 版本范围为 >=0.1.2-rc.1 <0.2.0 以及 >=0.1.5-alpha.1 <0.2.0,纯 JavaScript 实现,支持全平台运行,无需额外原生代码或网络依赖。

该插件在三个关键节点进行扫描检测:用户输入消息进入代理前、工具执行前、工具返回结果后。默认策略对普通风险请求人工确认,对严重敏感信息直接拦截,所有检测行为都会留下审计记录,不会影响下游其他策略插件的运行。适合需要提升 DSH 代理使用安全性,防范恶意输入和意外敏感信息泄露的开发者和普通用户。

该插件要求 Node.js 版本为 ^22.19.0 或 >=24.0.0,采用 Apache 2.0 开源许可,检测规则来自四个上游 Apache 2.0 授权的开源项目,相关第三方授权信息已单独整理在 THIRD_PARTY_NOTICES.md 文件中。首次安装后需要重启 DSH 才能生效,可通过 dump-config 命令验证插件是否成功加载。

DSH walks through these 9 checksDSH 会逐条核对这 9 项

Compatibility兼容性

  • DSH, Node, OS and profile requirementsDSH 版本 / Node 版本 / 操作系统 / profile 是否满足要求
  • External dependencies and runtimes (Electron / Python / Docker, ...)外部依赖与运行时(Electron / Python / Docker 等)是否齐备
  • Conflicts with installed plugins: command names, skill / tool names, ports, duplicate MCP registration与已装插件是否冲突:命令名、skill / tool 重名、端口占用、重复 MCP 注册

Security安全性

  • Repo matches the facts registered here; archived or abandoned?仓库是否与页面登记一致,是否归档或长期停更
  • Safety of preinstall / install / postinstall and install.sh / setup.ps1preinstall / install / postinstall 与 install.sh、setup.ps1 是否安全
  • curl|bash, download-then-execute, obfuscation, unrelated domains → stop immediatelycurl|bash、下载即执行、混淆代码、无关域名 → 立刻停止
  • Typosquatting or unmaintained packages among the new dependencies新增依赖里有没有 typosquatting 或无人维护的包
  • Requested permissions vs. what the feature actually needs申请了哪些权限、是否超出功能所需(filesystem / network / shell / clipboard)
  • Any sudo / admin requirement, plus uninstall and rollback是否要求 sudo / 管理员权限,以及卸载与回滚方式
