Financial Services Firm

Business Email Compromise (BEC)

A financial advisory firm nearly lost $420,000 in a wire fraud scheme. Because of DMARC enforcement and transaction verification controls, the fraudulent transfer was stopped before funds left the account.

 

One missing email authentication setting would have cost them nearly half a million dollars.

Incident Overview

  • Industry: Financial advisory
  • Employees: 11
  • Assets under management: $180M

 

An attacker spoofed the managing partner’s email and sent:

“Urgent client wire adjustment — needs to process today.”

 

The request looked legitimate:

  • Correct email signature
  • Accurate internal language
  • Timing aligned with quarter-end

Why It Failed

Because the firm had:

  • DMARC policy set to “reject”
  • SPF and DKIM properly configured
  • Wire transfer verification protocol (two-person confirmation)

 

The spoofed email was flagged and quarantined.

Additionally:

  • Accounting required verbal confirmation for any transfer over $50K.

 

Attack blocked.

Investigation Findings

The attacker:

  • Scraped LinkedIn profiles
  • Monitored public filings
  • Used social engineering timing

 

No malware was involved.

This was pure business email compromise.

Financial Impact Avoided

Potential loss: $420,000

Insurance deductible avoided: $25,000

Reputation damage prevented

What Changed After

  • Quarterly executive phishing drills
  • Dark web credential monitoring
  • Enhanced email anomaly detection
  • Client notification transparency policy

Key Lessons for Financial Firms

  • Email authentication (DMARC) is not optional.
  • Wire verification must be manual.
  • Attackers research your leadership.
  • BEC attacks are more common than ransomware in finance.
