Section 04: Intelligence Hints
Optional field for additional context, keywords, or investigator notes that may help with MO detection.
4. Understanding Results
After clicking Initialize Internet Verification, the system processes your inputs through five phases and displays comprehensive results.
Vector Summary
Visual display of geographic consistency across transaction vectors (Marketplace, BA, SA, CC, IC). Mismatches are highlighted for quick identification.
Network Intelligence
Interactive map powered by Leaflet.js showing:
- IP geolocation with precise coordinates
- ISP detection and identification
- VPN/Proxy detection (60+ provider database)
- Network origin analysis
Analysis Findings
Risk factors and MO detections with severity tags:
- CRITICAL: Immediate action required (e.g., Disposable Email, Tech Scam MO)
- HIGH: Significant risk indicator (e.g., Munged Address, Identity Theft Risk)
- INFO: Informational finding requiring review (e.g., Corporate MO Check)
- SAFE: Legitimate pattern detected, reduces false positive risk (e.g., Military MO)

6. MO Detection
Captain IV applies intelligent pattern recognition to identify both legitimate and fraud patterns.
Legitimate MOs (Reduce False Positives)
- Test/Internal Accounts: Ireland IP (Amazon HQ/Servers), "TEST ORDER" keywords
- Military MO: APO/FPO/DPO addresses, .mil/.gov domains, rank keywords
- Educational MO: .edu/.ac domains, campus/university keywords
- Corporate MO: LinkedIn employment verification
- Correctional MO: Inmate/prison keywords
- Reseller MO: Freight forwarder keywords (Aerocasillas, Shipito, etc.)
Fraud MOs
- Munged Address MO: Unnecessary prefixes (HOME:, TO:, SHIP:), repeated characters
- Tech Scam MO: Remote access keywords (TeamViewer, AnyDesk, LogMeIn)
- Family Fraud: Surname match between account holder and related person
- Identity Theft: Complex alphanumeric email mismatch with name
Email Domain Analysis
- Disposable Email (CRITICAL): yopmail.com, temp-mail.org, guerrillamail.com, etc.
- Privacy Email (HIGH): protonmail.com, tutanota.com, cock.li
- Risky Email (HIGH): gmx.com, gmx.net, mail.com (fraud history)
- Free Email (INFO): gmail.com, yahoo.com, hotmail.com
- Corporate/Private Domain (INFO): Any domain not in above lists

8. Best Practices
Investigation Workflow
- Gather Complete Data: Collect all available information before starting the investigation
- Review Vector Summary: Check for geographic consistency across transaction vectors
- Analyze Findings: Review severity tags (CRITICAL, HIGH, INFO, SAFE) in Analysis Findings
- Execute Top Queries: Use "OPEN TOP QUERIES" for priority investigation
- Verify Network Intelligence: Check IP geolocation and VPN/Proxy detection
- Leverage AI Analysis: Use Quick Suite or PartyRock for advanced insights
Common Scenarios
Scenario 1: Disposable Email Detected
- CRITICAL alert will appear in Analysis Findings
- Cross-reference with other risk factors (IP mismatch, High-Risk Country)
- Execute Email Intelligence queries (Hunter.io, HaveIBeenPwned)
Scenario 2: Military MO Detected
- SAFE tag indicates legitimate pattern
- Verify APO/FPO address format
- Check for .mil/.gov email domain
- Proceed with standard verification (not fraud indicator)
Scenario 3: IP/Shipping Mismatch
- HIGH alert for Disguised Address MO
- Check Network Intelligence for VPN/Proxy detection
- Verify if IP is in Ireland (possible Amazon internal/test account)
- Cross-reference with marketplace regional exceptions
Tips for Efficient Investigations
- Use Intelligence Hints field to document context or keywords
- Leverage Local OSINT Tools for marketplace-specific verification
- Review both SAFE and CRITICAL findings (SAFE reduces false positives)
- Combine OSINT results with AI analysis for comprehensive insights
- Document Case ID for audit trail (no PII stored)
