// SIMULATION — FINAL SUMMARY

The Full Picture

This is how a real executive impersonation attack works — and how it should be stopped.

Module 04 Simulation

The Meridian Financial BEC scenario demonstrates every stage of a modern executive impersonation attack — from domain spoofing and writing-style cloning to urgency manipulation and the verification cascade that stops it.

Domain spoofing detected ✓ YES

Dual-approval bypass recognized ✓ YES

Verified via known channel (not incoming) ✓ YES

Threat remained in isolated inbox ✓ YES

Incident escalated to security ✓ YES

// KEY TAKEAWAYS

1. The domain is the first signal. Check it every time. On mobile, the full domain may not be visible — expand the sender details manually before making any判断.

2. Verify on a channel you control. Call the executive from your CRM or saved contact. Do not call the number in the email. Do not reply to verify.

3. Urgency is a force multiplier for the attacker. "Must be done by EOD" and "I'm unavailable to call" are a package deal. Slow everything down intentionally.

4. Don't forward the threat. Describe the situation in a separate channel. If you forward a BEC email with tracking pixels or malicious links, you expose your colleague's inbox to the same risk.

5. The verification cascade is non-negotiable. For any financial request that bypasses normal approval — stop, call known number, escalate. No exceptions. The cost of stopping a real executive is one phone call. The cost of not stopping is $340K, a board incident, and a regulatory notification.
