BEC accounted for over $3 billion in reported losses last year alone. Most organizations don’t realize they’re exposed until it’s too late. Here’s how to tell if your defenses have gaps.

Instead, a finance team member processes what looks like a routine vendor payment update. A controller wires funds based on what appears to be a CFO’s direct request.

The FBI IC3’s 2024 Internet Crime Report documented $55 billion in cumulative BEC losses over the past decade, with $3 billion in 2024 alone — making it the most financially destructive enterprise-targeted cyber threat in the country.

The challenge with BEC is that it exploits trust, not technology. These attacks carry no malicious payload for a gateway to catch — just carefully crafted messages designed to manipulate human judgment. That makes traditional defenses largely blind to them. Here are seven signs that your organization may be more exposed than you think.

1. You’re Relying on Content-Based Filtering Alone

Secure email gateways and native platform filters were engineered to catch malicious content: infected attachments, known bad URLs, blacklisted sender domains. BEC attacks contain none of these indicators. They’re plain-text messages that impersonate trusted senders and request legitimate-sounding actions. If your email security strategy depends entirely on scanning for known threats, you have a structural blind spot for the fastest-growing category of email attacks.

2. You Can’t Detect Behavioral Anomalies in Email

BEC succeeds by mimicking normal communication patterns — but not perfectly. A spoofed CEO email might be sent at an unusual hour, use slightly different phrasing, or make a request that breaks from established workflows. Detecting these anomalies requires behavioral baselines: an understanding of who each…
