Account takeover in digital banking: are your controls keeping up?

TL;DR: Account takeover in digital banking now combines credential stuffing, phishing, malware, and support-channel abuse, with Veriff reporting that 2025 verification flows saw a fraud rate above 4% and impersonation made up more than 85% of attempts. Static authentication and fragmented fraud controls are no longer enough when attackers can move from access to monetisation in hours.

By the numbers:

• Impersonation fraud accounted for over 85% of all fraud attempts in 2025, underscoring how attackers are concentrating on identity-driven abuse.

Questions worth separating out

Q: How should banks reduce account takeover risk without making login unusable?

A: Use risk-based authentication so low-risk sessions stay friction-light while suspicious logins trigger stronger checks.

Q: Why do reused passwords still create account takeover risk in digital banking?

A: Reused passwords let attackers turn one breach into many login attempts at scale.

Q: What breaks when SMS-based MFA is the main defence against account takeover?

A: SMS breaks when attackers can intercept codes, swap SIMs, or trick support staff into resetting access.

Practitioner guidance

• Harden onboarding proofing for high-risk banking accounts Use document verification, liveness checks, and data cross-checks for accounts or actions with elevated fraud exposure.
• Replace SMS as the default recovery path Move high-risk authentication and recovery flows to app-based authenticators, passkeys, or hardware-backed methods.
• Treat call-centre workflows as privileged access Require multi-step verification before any contact-detail change, password reset, or payment-beneficiary update.
