CyberSecurityRSS

A curated cybersecurity RSS/Atom OPML collection for building a high-signal daily intelligence workflow.

中文文档

Highlights

• Two profiles for different reading budgets:
  • tiny.opml: focused daily reading (currently ~422 feeds / 9 categories)
  • CyberSecurityRSS.opml: broad coverage (currently ~735 feeds / 12 categories)
• Practical security coverage across vulnerability research, red team, reverse engineering, web security, threat news, and more.
• Automation-first maintenance: dead feed cleanup, deduplication, and tiny -> full sync.
• Ready for both manual reading and AI-assisted daily digest pipelines.

Quick Start

1. Choose your feed set:
   • Low-noise daily reading: tiny.opml
   • Full coverage: CyberSecurityRSS.opml
2. Import the OPML file into your favorite reader.
3. Start tracking updates as your personal security knowledge base.

Reader Examples

• Reeder (macOS / iOS)
• Feedly (Web / iOS / Android)
• yarr (self-hosted, cross-platform)
• Feeder / Zr / Anyant / Leaf

Files

• tiny.opml: streamlined high-signal security feed set.
• CyberSecurityRSS.opml: full feed set with wider topic coverage.
• others.md: hand-picked useful sites, including some without RSS.

AI Daily Digest (OpenClaw / Claude Code)

You can combine this repository with the Skills in zer0yu/sec-daily-digest to generate an automated curated daily cybersecurity digest.

Recommended workflow:

1. Install sec-daily-digest Skills in OpenClaw or Claude Code (follow that repository's guide).
2. Use tiny.opml as default input (or CyberSecurityRSS.opml for broader coverage).
3. Run once per day (for example, every morning) with a 24-hour time window.
4. Output a structured report, such as:
   • Top picks
   • Vulnerabilities & exploitation
   • Threat intelligence & incidents
   • Research / tooling
   • Actionable takeaways

Prompt example:

Use CyberSecurityRSS feeds to generate a curated daily security digest for the last 24 hours.
Keep only high-signal items, group by topic, and include title, why-it-matters, and source URL.

Repository Automation

This repository uses GitHub Actions to keep OPML files healthy and synced:

1. pull_request -> master: runs in check mode and fails when OPML drift is detected.
2. push -> master: runs in apply mode:
   • Validate RSS/Atom feed URLs in tiny.opml and CyberSecurityRSS.opml.
   • Remove dead feed entries and deduplicate by xmlUrl.
   • Sync valid feeds from tiny.opml into CyberSecurityRSS.opml.
   • Fallback missing categories to Misc.
   • Keep .github/opml-health-state.json and only remove feeds after consecutive hard failures.
   • Auto-commit OPML changes with [skip ci].

Local Validation

python3 -m unittest discover -s tests -v

python3 scripts/opml_sync.py \
  --mode check \
  --tiny tiny.opml \
  --full CyberSecurityRSS.opml \
  --fallback-category Misc \
  --timeout 10 \
  --retries 3

Add New RSS Into tiny.opml (Interactive)

Use this helper script when you discover a new feed URL:

uv run python scripts/add_feed_to_tiny.py

Default behavior:

• Runs git pull --ff-only first to reduce local/remote drift before editing.
• Prints current top-level categories in tiny.opml.
• Lets you select a category by number or type a new name (auto-create).
• Fetches feed metadata (title/site link) from your RSS URL, then appends it.

Common options:

# Non-interactive
uv run python scripts/add_feed_to_tiny.py \
  --url "https://example.com/feed.xml" \
  --category "ThreatIntel"

# Skip startup git pull
uv run python scripts/add_feed_to_tiny.py --no-git-pull

OPML/XML Compatibility

Some readers only accept a specific extension. You can safely rename files:

cp CyberSecurityRSS.opml CyberSecurityRSS.xml
cp tiny.opml tiny.xml

Contributing

Contributions are welcome.

• Submit an Issue or PR for high-quality feeds.
• Include feed URL, category suggestion, and why it is valuable.
• Run local checks before opening the PR.
