Business Email Compromise (BEC) is the most financially damaging form of cybercrime. The FBI reports $2.7 billion in losses from BEC in a single year. Unlike ransomware, BEC attacks require no malware — they exploit human trust.
How email compromise reaches payment workflows
Business Email Compromise is a social engineering attack where criminals impersonate a trusted person — usually a CEO, CFO, vendor, or attorney — to trick an employee into transferring funds or sharing sensitive information. The FBI's Internet Crime Complaint Center reported $2.7 billion in BEC losses in 2022, making it the most financially destructive category of cybercrime.

Controls and independent verification
BEC attacks succeed because they bypass technical security controls. There is no malicious attachment to scan, no suspicious link to block — just a convincing email that appears to come from someone the victim trusts. Common BEC scenarios include CEO fraud (fake urgent wire transfer requests), vendor impersonation (fraudulent invoice with changed bank details), and attorney impersonation (fake legal matter requiring immediate payment).

Explore Managed Security (MSSP)Prevention requires a layered approach combining technology and process controls. Technical controls: deploy Microsoft Defender for Office 365 or similar email security with AI-powered impersonation detection, enable DMARC/DKIM/SPF on your domain, configure external email banners to flag messages from outside your organization. Process controls: establish dual-approval requirements for any wire transfer over $5,000, require phone verification (using a known number, not the one in the email) for bank account changes, and never process urgent payment requests without verbal confirmation. Training: conduct monthly phishing simulations and BEC-specific awareness training. CloudTechForce includes all three layers in our managed security service.
