Money Movement Investigation Techniques

🔍 Money Movement Investigation Techniques

The Art and Science of Following the Money

Money movement investigation combines traditional detective work with cutting-edge technology to trace fraudulent transactions across complex financial networks. Success requires understanding both the technical infrastructure of payment systems and the behavioral patterns of fraudsters.

This comprehensive guide covers advanced investigation methodologies used by fraud professionals to uncover, analyze, and prosecute money movement fraud.

Pattern Recognition

Behavioral Signatures

Common Fraud Patterns:
• Round-number transactions ($1,000, $5,000, $10,000)
• Just-under-threshold amounts ($9,999, $2,999)
• Repetitive timing (same time daily, weekly patterns)
• Geographic clustering (multiple transactions from same location)
• Sequential account numbers or similar naming patterns

Network Analysis

Account Clustering: Groups of accounts with similar characteristics
Beneficiary Analysis: Common recipients across multiple transactions
Originator Patterns: Common sources of fraudulent transactions
