Performing AI-Driven OSINT Correlation

When to Use

You have collected raw OSINT data from multiple tools and sources but need to identify connections, contradictions, and patterns across them.
You need to build a unified intelligence profile for a target entity (person, organization, or infrastructure) from fragmented data.
Traditional manual correlation is too slow or error-prone for the volume of data collected.
You want confidence-scored assessments of identity linkage across platforms rather than simple keyword matching.

Prerequisites

Workflow

Legal & Ethical Requirements

Obtain documented written authorization before any investigation
Establish lawful basis for data processing (law enforcement, corporate policy, etc.)
Define PII retention limits and data handling procedures
Comply with local privacy regulations (GDPR, CCPA, etc.)

Phase 1 — Multi-Source OSINT Collection

Create the working directory for all OSINT outputs:
```
mkdir -p /tmp/osint
```

Enumerate usernames across platforms with Sherlock:

sherlock "targetusername" --output /tmp/osint/sherlock-results.txt --csv

Harvest emails, subdomains, and hosts with theHarvester:

theHarvester -d targetdomain.com -b all -f /tmp/osint/harvester-results.json

Run a SpiderFoot passive scan via REST API:

curl -s http://localhost:5001/api/scan/start \
  -d  \
  | jq

Query breach databases for email exposure (example with HIBP API):

curl -s -H "hibp-api-key: ${HIBP_KEY}" \
  -H "User-Agent: OSINT-Correlation-Skill" \
  "https://haveibeenpwned.com/api/v3/breachedaccount/target@example.com" \
  -o /tmp/osint/breach-results.json

Normalize all collected data into a common schema. Create a unified JSON structure that tags each finding with its source, timestamp, and data type:

cat > /tmp/osint/normalize.py << 'EOF'
import json, csv, sys, os
from datetime import datetime

findings = []

# Normalize Sherlock CSV results
sherlock_path = "/tmp/osint/sherlock-results.txt"
if os.path.exists(sherlock_path):
    with open(sherlock_path) as f:
        for row in csv.DictReader(f):
            findings.append({
                "source": "sherlock",
                "type": "social_profile",
                "platform": row.get("name", ""),
                "url": row.get("url_user", ""),
                "username": row.get("username", ""),
                "status": row.get("status", ""),
                "collected_at": datetime.utcnow().isoformat()
            })

# Normalize theHarvester JSON results
harvester_path = "/tmp/osint/harvester-results.json"
if os.path.exists(harvester_path):
    with open(harvester_path) as f:
        data = json.load(f)
        for email in data.get("emails", []):
            findings.append({
                "source": "theHarvester",
                "type": "email",
                "value": email,
                "collected_at": datetime.utcnow().isoformat()
            })
        for host in data.get("hosts", []):
            findings.append({
                "source": "theHarvester",
                "type": "hostname",
                "value": host,
                "collected_at": datetime.utcnow().isoformat()
            })

# Normalize SpiderFoot results
sf_path = "/tmp/osint/spiderfoot-results.json"
if os.path.exists(sf_path):
    with open(sf_path) as f:
        for item in json.load(f):
            findings.append({
                "source": "spiderfoot",
                "type": item.get("type", "unknown"),
                "value": item.get("data", ""),
                "module": item.get("module", ""),
                "collected_at": datetime.utcnow().isoformat()
            })

with open("/tmp/osint/normalized-findings.json", "w") as f:
    json.dump(findings, f, indent=2)

print(f"Normalized {len(findings)} findings from {len(set(f['source'] for f in findings))} sources")
EOF
python3 /tmp/osint/normalize.py

Send normalized findings to an LLM for cross-source correlation analysis:

cat > /tmp/osint/correlate.py << 'PYEOF'
import json, os
from openai import OpenAI  # or anthropic, ollama, etc.

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

with open("/tmp/osint/normalized-findings.json") as f:
    findings = json.load(f)

correlation_prompt = f"""You are an OSINT analyst. Analyze these findings collected
from multiple sources and produce a correlation report.

For each identity or entity you detect:
1. List all linked accounts/profiles with the evidence connecting them.
2. Assign a confidence score (0.0-1.0) for each linkage based on:
   - Exact username match across platforms (high)
   - Similar usernames with shared metadata (medium)
   - Same email in breach data and registration (high)
   - Co-occurring infrastructure (IP, domain) (medium)
   - Temporal correlation of account creation dates (low-medium)
3. Identify contradictions or potential false positives.
4. Flag high-risk exposures (breached credentials, PII leaks, infrastructure overlaps).
5. Produce a structured JSON report.

# Extract entities and build a link graph

    confidence = entity.get("confidence", 0)
    links = entity.get("linked_accounts", [])
    risk = entity.get("risk_level", "unknown")
    print(f"  [{confidence:.0%}] {name} — {len(links)} linked accounts — risk: {risk}")

    writer.writerow(["Entity Type", "Value", "Linked To", "Link Label", "Confidence"])
    for entity in report.get("entities", []):
        for link in entity.get("linked_accounts", []):

                link.get("type", "Alias"),
