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.
NHIMG editorial — based on content published by Veriff: Deep dive on how to prevent account takeovers in digital banking [2026]
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.

Account takeover exposes a control-plane failure, not just a login failure. The banking programme often treats authentication, support verification, and transaction review as separate functions, but attackers chain them together. Once one path is compromised, the account can be repurposed for transfers, beneficiary changes, and identity fraud. Practitioners should read ATO as evidence that the customer identity lifecycle is being governed in fragments rather than as a single risk surface.
A few things that frame the scale:
- Two-thirds of enterprises have endured a successful cyberattack resulting from compromised non-human identities, with a quarter encountering multiple attacks, according to The 2024 ESG Report: Managing Non-Human Identities.
- Enterprises that have experienced a compromised NHI averaged 2.7 separate incidents in the past 12 months, a pattern that shows how compromise rarely stays isolated.
A question worth separating out:
Q: Who is accountable when an account takeover succeeds through support-channel abuse?
A: Accountability sits with the bank’s identity, fraud, and service-operations owners together, because the attacker exploited an operational recovery path, not only a login flow. Strong governance means support actions are treated as privileged events with auditable verification and clear ownership for approvals.
