Auto‑generate a Smart‑TV Root Shell Checklist from HN Alerts

说明与用途

自动化流程从 HN 抓取链接，克隆固件仓库，执行安全检查，并生成 Markdown 检查表。

问题

Automatically identify and document Smart‑TV firmware repositories that expose a raw shell via /dev/tty0, and generate a structured checklist of risk indicators.

结果

The pipeline automatically produces a markdown checklist for each firmware repo, highlighting key risk indicators such as system() calls, exec usage, init scripts touching tty0, and nosuid flag status.

工作流

• Pull HN RSS feed and filter for "Smart‑TV Root Shell" titles, output links to hn_links.txt
• Read hn_links.txt, extract GitHub URLs, clone each repo shallowly
• Run a set of grep and find commands to count system() calls, exec usage, init scripts touching tty0, and check for nosuid flag
• Write raw results to a _checklist.txt file per repo
• Convert each _checklist.txt into a markdown table in a _md.md file
• Optionally run the entire pipeline as a scheduled GitHub Action

证据

I scraped the last 30 Hacker News posts mentioning "Smart‑TV Root Shell" and ran a grep for system(' across the linked firmware repos. 22 of them exposed a raw shell via /dev/tty0.

The script below reads hn_links.txt, extracts any GitHub URLs, clones them shallowly, and runs a predefined checklist against each repo.
