TL;DR: Device-level fraud is broadening across mobile banking, with 34 malware families aimed at 1,243 banking and fintech apps in 90 countries, according to Zimperium. Runtime integrity checks and behavioural detection matter because the handset is now part of the fraud path.
Editorial analysis by NHI Mgmt Group, based on content published by Zimperium: “Mobile Banking Fraud 2026: Malware Is Actively Targeting Mobile Banking Apps in the US and Canada”.
By the numbers:
- 34 malware families targeting 1,243 mobile banking and fintech apps across 90 countries globally
- 26 mobile malware families are actively targeting over 189 banking and fintech applications in the US and Canada
- 162 banking and fintech apps are being targeted by 26 active malware families in the United States
Key questions
Q: Why do mobile banking malware campaigns create more risk than credential theft alone?
A: Because they compromise the point where the customer makes trust decisions.
Q: How can security teams tell whether mobile fraud controls are working?
A: Look for earlier containment, not just better post-event detection.
Q: What should mobile banking teams do first when device-based fraud is targeting their apps?
A: Start with runtime integrity controls that can detect tampering, rooting, jailbreaks, overlays, and suspicious automation before a sensitive session is allowed to proceed.
Practitioner guidance
- Harden the mobile app against tampering Reduce the usefulness of reverse engineering, debugger attachment, hooking frameworks, and emulator-based analysis so attackers cannot easily inspect or modify app behaviour.
- Enable runtime protection for mobile sessions Detect root, jailbreak, accessibility abuse, screen manipulation, and suspicious runtime conditions before allowing high-risk banking actions.
- Add anti-overlay and transaction-verification checks Make approval screens harder to spoof and require stronger verification when the app detects display substitution or abnormal interaction paths.
Bottom line: Mobile banking fraud is increasingly driven by malware that compromises the handset and manipulates the session, not just by phishing against the login page.

Mobile fraud is now a device trust problem, not only a banking-app problem. When malware can sit in front of the user, the app may still be intact while the session is already compromised. That shifts governance toward runtime integrity, device posture, and approval-flow assurance rather than only backend authentication. Financial security teams should treat the handset as part of the control boundary.
A few things that frame the scale:
- Nearly 60% of companies reported that fraud losses were still increasing in 2025.
A question worth separating out:
Q: Should organisations prioritise runtime controls over malware signatures for mobile fraud defence?
A: Yes, when the threat model includes fast-changing malware families and AI-assisted variation. Signatures still matter, but they lag behind new samples and altered overlays. Runtime controls are better for catching the conditions that make mobile fraud possible, especially when the attacker is using the device itself as the attack surface.
