AI Fraud Detection & Benford's Law

The $450,000 Embezzlement AI Caught

Medium-sized manufacturing company, trusted bookkeeper of 8 years. AI flagged unusual patterns in vendor payments. Investigation revealed she'd been creating fake vendors and pocketing checks.

What AI Detected:

  • • Payments always just under approval threshold ($9,950 when limit was $10,000)
  • • Vendor invoices numbered sequentially (1001, 1002, 1003) - fake pattern
  • • Payment amounts violated Benford's Law (too many 9s as first digit)
  • • Payments scheduled during bookkeeper's approval windows
  • • No purchase orders matched to these vendors

Total stolen over 3 years: $450,000. Would have continued if AI hadn't flagged it.

Benford's Law Explained

Benford's Law states that in many naturally occurring datasets, the first digit is 1 about 30% of the time, 2 about 18%, decreasing to 9 at 5%. Fraudulent data often violates this pattern because humans making up numbers tend to use digits evenly.

Expected vs. Fraudulent Patterns:

First Digit 1:Expected: 30% | Fraud often: 11-15%
First Digit 9:Expected: 5% | Fraud often: 15-20%

AI can detect these deviations automatically, flagging accounts for review.

Other Fraud Patterns AI Detects:

  • • Round Number Fraud: Legitimate expenses rarely end in .00 (AI flags excessive round numbers)
  • • Threshold Avoidance: Amounts clustering just below approval limits
  • • Time Pattern Anomalies: Transactions always on same day of week/month
  • • Vendor Similarity: Similar names, addresses, or bank accounts
  • • Statistical Outliers: Purchases way outside normal ranges
  • • Ghost Employees: Payroll recipients with no time records
