CyberSecurityRSS

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

This repository provides a high-signal intelligence pipeline based on Dual Data Sources (Security RSS + Twitter/X Researchers):

| Tier | Scale | Content | |------|-------|---------| | 📡 RSS (Tiny) | 494 Feeds | tiny.opml — Focused daily reading including AI, WebSecurity, RedTeam, Reverse, Pwn... (9 categories) | | 📡 RSS (Full) | 1000+ Feeds | CyberSecurityRSS.opml — Comprehensive coverage across 12 categories |

Highlights

• Two profiles for different reading budgets:

- tiny.opml: focused daily reading (currently 494 feeds / 9 categories) - CyberSecurityRSS.opml: broad coverage (currently ~1014 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

• Choose your feed set:

- Low-noise daily reading: tiny.opml - Full coverage: CyberSecurityRSS.opml

• Import the OPML file into your favorite reader.
• 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:

• Install sec-daily-digest Skills in OpenClaw or Claude Code (follow that repository's guide).
• Use tiny.opml as default input (or CyberSecurityRSS.opml for broader coverage).
• Run once per day (for example, every morning) with a 24-hour time window.
• 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:

• pull_request -> master: runs in check mode and fails when OPML drift is detected.
• 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/addfeedto_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/addfeedto_tiny.py \
  --url "https://example.com/feed.xml" \
  --category "ThreatIntel"
Skip startup git pull
uv run python scripts/addfeedto_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.
