源代码安全审计

用于授权源代码安全审查和SAST工作流，包括Semgrep、CodeQL模式、危险API检测和修复验证。

源代码安全审计 是什么？

这是一个专为授权白盒源代码安全审计设计的技能，适用于AI代理（如Claude Code）进行静态应用程序安全测试（SAST）。它支持Semgrep、CodeQL、Bandit、gosec等多种工具，覆盖多语言场景。工作流包括威胁建模、自动扫描和人工验证，确保每个SAST命中点都被评估可达性和可利用性。该技能要求确认源码/仓库访问权限，并强调人工验证而非仅依赖扫描器输出，最终产出包含位置、数据流、PoC和修复建议的发现报告。

文档

源代码安全审计 是做什么的？

立即执行（读完后立刻执行）

  1. NOW: 读取 ../field-journal/precedent-pentest.md 或代码审计授权
  2. NOW: 确认有源码/仓库访问（无源码二进制 → 转 RE skill）
  3. NOW: 明确语言栈与范围（目录/服务/PR diff）
  4. NEXT: tool-index；semgrep 等
  5. ACT: 威胁建模草图 → 自动扫描 → 人工验证

适用场景

  • 白盒审计、PR/差分安全审查
  • Semgrep / CodeQL / Bandit / gosec 等 SAST
  • 危险 API、注入点、鉴权缺失、加密误用
  • 与 supply-chain-security/ 分工：本 skill 偏自有代码逻辑，供应链偏依赖与管道

工作流

1. 范围与威胁模型

□ 信任边界：用户输入、文件、反序列化、SSRF、鉴权中间件
□ 高价值资产：鉴权、支付、管理端、密钥处理

2. 自动扫描

semgrep --config auto .
# 或项目规则包
semgrep --config p/owasp-top-ten .

3. 人工验证（必须执行）

□ 每个 SAST 命中：可达性？可利用性？误报？
□ 鉴权：IDOR/越权、缺校验、错误的多租户隔离
□ 注入：SQL/命令/模板/LDAP
□ 加密：硬编码密钥、ECB、自定义 crypto

4. 产出

发现项：位置 + 数据流 + PoC + 修复建议
可选 ATT&CK / CWE 编号

工具链

工具语言/场景
Semgrep多语言快速规则
CodeQL深数据流（GitHub）
BanditPython
gosec / staticcheckGo
SpotBugs / FindSecBugsJava

参考

  • references/sast-review-checklist.md
  • ../supply-chain-security/ ../api-security/ ../llm-security/（Agent 代码）

路由上下文

上游: MASTER R26
角色: ops/role-map.md cae
下游: 依赖漏洞 → supply-chain；运行时验证 → pentest-tools

任务完成自检

  • 是否人工验证而非只贴扫描器输出？
  • 是否含修复建议？
  • 是否限定在授权仓库范围？
  • Checklist？

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

api-security

Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.

apk-reverse

在 CLI 环境下做 Android APK 逆向时使用。适用于 APK 解包、Java 反编译、smali 修改、重打包、Frida 动态 Hook，以及按需切换到 so/native 分析。优先使用本机已安装的 jadx、apktool、frida、adb、ida-reverse、radare2。

attack-chain

Use for authorized multi-stage attack-path planning and orchestration when a task spans reconnaissance, initial access, privilege escalation, lateral movement, or impact assessment. Route single-stage tasks directly to their specialist skill.

binary-diff

binary-ninja-reverse

Use for authorized binary analysis in Binary Ninja, including HLIL/MLIL/LLIL inspection, strings/imports/exports, cross-references, types, patch review, Python API automation, and optional Binary Ninja MCP or localhost HTTP integration.

browser-automation

|

browser-extension-reverse

Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.

case-review

Reviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.

cloud-k8s

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

ctf-sandbox

Thin PRIMARY for CTF / AWD / 靶场 multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, 靶场, or 比赛题 and no more specific pwn/APK/IDA route already won.

database-security

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

diagram-generator

generate, refine, validate, and render diagrams from natural language, notes, code snippets, schemas, tables, or existing diagram source. use for flowcharts, swimlanes, sequence diagrams, state diagrams, er diagrams, class diagrams, architecture/c4-style diagrams, dependency graphs, gantt charts, mind maps, user journeys, sankey-style flows, org charts, network graphs, and other visual models. supports mermaid by default, graphviz dot for complex graph layout, plantuml for uml-heavy engineering diagrams, and svg output when direct markup is more reliable.
