OSINT Daily Brief

Automated open-source intelligence report for any target.

Pulls from Tavily AI search, DNS records, WHOIS, and optionally Shodan. Structures findings into a daily brief you can read in under 2 minutes.

Use for: competitive intel, brand monitoring, pre-engagement recon, daily threat feeds.

Prerequisites

# Required
TAVILY_API_KEY=your_key_here        # tavily.com → free: 1,000 searches/month

# Optional — for richer results
SHODAN_API_KEY=your_key_here        # shodan.io → free tier available

Workflow

1. Web intelligence (Tavily)

import os, requests

def tavily_search(query: str, max_results: int = 5) -> list[dict]:
    """AI-optimized web search — returns full page content, not just snippets."""
    r = requests.post(
        "https://api.tavily.com/search",
        json={
            "api_key":     os.environ["TAVILY_API_KEY"],
            "query":       query,
            "max_results": max_results,
            "search_depth": "advanced",
        },
        timeout=15,
    )
    return r.json().get("results", [])

# Example: monitor a target
target = "example.com"
news   = tavily_search(f"{target} security breach data leak 2026")
tech   = tavily_search(f"{target} technology stack infrastructure")

2. DNS recon

import subprocess

def dns_recon(domain: str) -> dict:
    results = {}
    for record_type in ["A", "MX", "NS", "TXT"]:
        try:
            r = subprocess.run(
                ["dig", "+short", record_type, domain],
                capture_output=True, text=True, timeout=5
            )
            results[record_type] = r.stdout.strip().split("\
")
        except Exception:
            results[record_type] = []
    return results

3. WHOIS

def whois_lookup(domain: str) -> str:
    try:
        r = subprocess.run(
            ["whois", domain],
            capture_output=True, text=True, timeout=10
        )
        # Extract key fields only
        lines = r.stdout.split("\
")
        relevant = [l for l in lines if any(k in l.lower() for k in
            ["registrar", "created", "expires", "registrant", "name server"])]
        return "\
".join(relevant[:15])
    except Exception as e:
        return f"WHOIS error: {e}"

4. Shodan (optional)

def shodan_lookup(ip_or_domain: str) -> dict:
    key = os.environ.get("SHODAN_API_KEY")
    if not key:
        return {"error": "SHODAN_API_KEY not set"}
    try:
        r = requests.get(
            f"https://api.shodan.io/shodan/host/{ip_or_domain}",
            params={"key": key},
            timeout=10
        )
        data = r.json()
        return {
            "ports":   data.get("ports", []),
            "org":     data.get("org", ""),
            "country": data.get("country_name", ""),
            "vulns":   list(data.get("vulns", {}).keys())[:5],
        }
    except Exception as e:
        return {"error": str(e)}

Scheduling — daily brand/target monitoring

# Monitor your own domain daily
openclaw cron add \
  --name "osint-brief:daily-self" \
  --cron "0 6 * * *" \
  --prompt "Run osint-daily-brief skill on target: yourdomain.com. Send report to Telegram."

# Monitor a competitor
openclaw cron add \
  --name "osint-brief:daily-competitor" \
  --cron "0 6 * * *" \
  --prompt "Run osint-daily-brief skill on target: competitor.com. Flag any new exposed ports, CVEs, or breach mentions."

Use cases

Privacy & ethics

• Only investigate targets you own or have explicit authorization to research
• All data comes from public sources (Tavily, DNS, WHOIS, Shodan)
• No social engineering, credential testing, or active probing
• WHOIS and Shodan data is public by design — this skill reads it, does not generate it
• Comply with applicable laws in your jurisdiction

Notes

• Tavily free tier: 1,000 searches/month. Each run uses ~3–5 searches.
• Shodan free tier: limited to 1 result per query on some endpoints
• DNS recon requires dig installed: sudo apt install dnsutils
• WHOIS requires whois installed: sudo apt install whois
• For dark web mentions, pair with Tor proxy (Ahmia search via SOCKS5)
