Preventing business email compromise and fraudulent wire transfers during commercial and residential property transactions.

Published: 2026-09-28

Stopping Email Hijacking at Closing

Real estate brokerages and title agents remain primary targets for email interception attacks[cite: 2]. Fraudsters silently monitor email threads to substitute wire instructions right before closing dates[cite: 2].

Verification Standards

  • Out-of-Band Call Verification: Require verbal telephone confirmation via verified numbers before initiating any funds transfer[cite: 2].
  • Conditional Access Policies: Restrict employee email access strictly to trusted devices and locations.
  • DKIM, DMARC, and SPF Enforcement: Prevent hackers from spoofing your brokerage's email domain name.
