brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation).
detecting-supply-chain-attacks-in-ci-cd扫描 GitHub Actions 工作流和 CI/CD 流水线配置,检测供应链攻击(Supply Chain Attack)向量, 包括未固定的 Action 版本、通过表达式的脚本注入、依赖混淆(Dependency Confusion)和密钥泄露。 使用 PyGithub 和 YAML 解析进行自动化审计。适用于加固 CI/CD 流水线或调查被攻击的构建系统。

通过解析 GitHub Actions YAML 文件,检查未固定的依赖、脚本注入向量和密钥泄露,扫描 CI/CD 工作流文件中的供应链风险。
import yaml
from pathlib import Path
for wf in Path(".github/workflows").glob("*.yml"):
with open(wf) as f:
workflow = yaml.safe_load(f)
for job_name, job in workflow.get("jobs", {}).items():
for step in job.get("steps", []):
uses = step.get("uses", "")
if uses and "@" in uses and not uses.split("@")[1].startswith("sha"):
print(f"Unpinned action: {uses} in {wf.name}")
关键供应链风险:
${{ github.event }} 表达式的脚本注入# 检查 run 步骤中的脚本注入
for step in job.get("steps", []):
run_cmd = step.get("run", "")
if "${{" in run_cmd and "github.event" in run_cmd:
print(f"Script injection risk: {run_cmd[:80]}")
