The OWASP Mobile Top 10 was refreshed for 2026, reflecting a threat landscape where on-device AI, alternative billing and cross-platform frameworks have changed where mobile risk concentrates. For engineering teams, the list remains the cheapest available map of what to check before shipping.
Improper platform usage
Misconfigured exported components, excessive permissions, and weak inter-app communication remain common. Audit the manifest explicitly: every exported component and requested permission should have a justification you can state.
Insecure data storage
Tokens and personal data in plain storage, logs, or backups leak through device compromise and forensic access. Use platform secure storage, disable backups for sensitive data, and keep secrets out of logs entirely.
Insufficient cryptography and transport
Custom crypto, certificate pinning gaps, and cleartext fallbacks undermine everything else. Use platform crypto primitives, pin certificates for sensitive endpoints, and forbid cleartext traffic in production builds.
What changed in the current edition
The categories continue the shift from device-centric issues (jailbreak detection as a silver bullet) toward data and platform realities: improper platform usage, insecure data storage on modern sandboxes, insufficient cryptography, and business logic abuse such as payment manipulation and parameter tampering. AI features add a new angle — model extraction and prompt-driven data leakage from on-device inference — which the current guidance treats as data-protection problems rather than model problems.
Turning the list into engineering work
The Top 10 earns its value when mapped to controls with owners: a static analysis rule for each mechanical item, a review checklist item for each design item, and a penetration test covering the business-logic items automation cannot judge. Pair it with MASVS for the requirements side — MASVS says what to implement, the Top 10 says what attackers prioritize. Revisit the mapping annually; the checklist that is not re-derived from the current list quietly becomes folklore.
Key takeaways
- Risk has moved toward data handling, platform misuse and business logic.
- Map each category to a control with a named owner.
- Pair with MASVS: requirements plus attacker priorities.
Final thoughts
The Mobile Top 10 is a living threat summary rather than a compliance artifact, and teams that re-derive their control mapping from it each year keep their mobile security posture aligned with how attacks actually evolve.
