Setup

pip install python-telegram-bot feedparser aiohttp beautifulsoup4

Create .env:

BOT_TOKEN=your_token_here
MIN_QUALITY_SCORE=0
ALLOWED_SEVERITIES=critical,high,medium,low

Run:

python3 threat_intel_bot.py

Bot Commands

Command	Action
`/on_<category>`	Subscribe this chat/topic to a category
`/off_<category>`	Unsubscribe
`/stats`	Check feed health and subscriber count
`/help`	Show commands

Categories: news, malware, threat_intel, osint, research

Telegram Topics: Run /on_<category> inside each topic to route categories to separate threads.

Feed Management

Each feeds/*.json file follows this structure:

{
  "category_name": {
    "Feed Display Name": "https://example.com/rss.xml"
  }
}

Add or remove feeds by editing the JSON, then restart the bot. Run python3 check_feeds.py to verify feed health before deploying.

Message Format

Each alert follows this structure:

{emoji} Title

Description

📡 Source  ·  Published (UTC)
🆔 CVE-2024-1234, CVE-2024-5678      (only if CVEs detected)
👤 APT28, Fancy Bear                  (only if threat actors detected)
🦠 LockBit, Cobalt Strike             (only if malware families detected)

🔗 Read Full Article

The enrichment lines (CVEs, actors, malware) only appear when the classifier finds something — clean articles stay minimal.

Classification

content_classifier.py extracts the following from article title + description:

CVEs — standard CVE-YYYY-NNNNN pattern matching.

Threat actors — APT groups and named adversaries: APT28/29/40/41, Lazarus, Sandworm, Volt Typhoon, Scattered Spider, FIN7, and others defined in THREAT_ACTORS.

Malware families — ransomware, C2 frameworks, loaders, stealers, and APT tooling: LockBit, Cobalt Strike, Emotet, QakBot, Sliver, PlugX, and others defined in MALWARE_FAMILIES. To add a family, append its display name to the set — matching is case-insensitive.

Severity is keyword-based:

critical — zero-days, active exploitation, RCE, ransomware
high — privesc, auth bypass, code execution, kernel exploits
medium — XSS, CSRF, DoS, memory corruption
low — everything else

Quality score (0–100) factors in: source reputation, content length, CVE presence, PoC indicators, threat actor mentions.

Filter via env vars:

MIN_QUALITY_SCORE=50
ALLOWED_SEVERITIES=critical,high

Notes

First run marks all current articles as seen — no flood on startup

Only today's UTC articles are processed (strict date gate in rss_manager.py)
seen_articles.db auto-purges entries older than 7 days
