TL;DR: Spoofing now works by abusing trust across email, DNS, and social channels, and GlobalSign says that makes it a governance issue as much as a technical one. Email and identity controls need layered verification before deceptive requests become business actions.
Editorial analysis by NHI Mgmt Group, based on content published by GlobalSign: “Spoofing-Angriffe erklärt – Arten, Risiken und wie man sie aufhält”.
Key questions
Q: Why do MFA spoofing attacks still succeed even when two-factor authentication is enabled?
A: MFA spoofing succeeds because attackers target the human step in the process.
Q: What are the signs that location spoofing controls are failing in practice?
A: Common signs include mismatches between IP location and browser time zone, system language, keyboard layout, or network behavior.
Q: What breaks when attackers hijack trusted email accounts instead of spoofing domains?
A: Sender authentication still works, but it no longer protects the user from abuse of a legitimate identity.
Practitioner guidance
- Harden domain authentication Enforce SPF, DKIM, and DMARC with a policy that rejects unauthorised mail, then review alignment for all external domains that send on behalf of the organisation.
- Add high-risk verification steps Require callback, secondary approval, or out-of-band confirmation for payments, mailbox changes, and executive requests that arrive through email or chat.
- Use DNSSEC where redirection risk matters Protect critical domains with DNSSEC and monitor for resolver or zone tampering that could redirect users to spoofed destinations.
Bottom line: Spoofing exploits trust assumptions across email, DNS, and social channels, which makes it a governance problem as much as a technical one.

Spoofing is now an identity governance problem, not just a messaging problem. The article's strongest point is that attackers increasingly win by borrowing legitimacy across channels, then using that legitimacy to drive fraud or access. That means the control boundary is no longer confined to email security teams; it extends into identity verification, domain trust, and the human decision points where authority is accepted. Practitioners should treat spoofing as a cross-domain assurance failure, not a mail hygiene issue.
A question worth separating out:
Q: How should security teams reduce spoofing risk in email and voice workflows?
A: Security teams should validate identity at the protocol edge, not rely on what the user sees in the interface. For email that means SPF, DKIM and DMARC, and for voice it means carrier and boundary checks on caller identity. High-risk actions should always require an independent verification channel.
