Vendor Email Compromise (VEC)

Attack Trigger

Compromised legitimate supplier email account redirecting payment to attacker-controlled account

What Attackers Want

$10,000–$5,000,000+ depending on transaction size; recovery is rare once wired

How This Attack Works

Unlike spoofed vendor emails, Vendor Email Compromise involves criminals who have actually taken over a real supplier's email account. They monitor correspondence silently, then intercept an active invoice thread and replace banking details with their own. Because the email originates from a genuine account, DKIM and SPF checks pass, making this attack exceptionally hard to detect without out-of-band verification.

Red Flags to Watch For

  • Banking detail change request arrives mid-conversation in an existing invoice thread
  • New account details are in a different country from the supplier's registered address
  • The supplier's email replies become slightly delayed or the tone shifts subtly
  • Wire transfer confirmation receipts stop arriving as normal after a payment
  • SPF and DKIM pass but the bank account is newly registered or offshore
  • Supplier calls to ask about a missing payment you believe was already sent
