Prevent Email Spoofing

Prevent Email Spoofing

Email spoofing forges or misrepresents sender identity so a message appears to come from a trusted vendor, executive, or domain. Fraudsters use spoofing and look-alike domains to request payments, share fake invoices, or escalate urgency.

How Vantirs detects this attack type

Vantirs correlates sender domains and communication patterns with each vendor’s established profile. When an invoice-related message comes from an unfamiliar or look-alike domain, it is flagged alongside bank and amount checks for a unified review.

Prevention checklist

Use this list alongside Vantirs to tighten controls and make reviews consistent across clients and bookkeepers.

  • Deploy SPF, DKIM, and DMARC; monitor DMARC reports for abuse.
  • Train users to inspect full headers and domains on financial emails.
  • Maintain allowlists for vendor billing addresses and domains.
  • Use a dedicated AP inbox with rules for invoice submission.
  • Never authorize wires based solely on email content.
