Key risk areas in Neobanks

Traditional banks move slowly to avoid risk. Digital banks move fast, meaning security testing must adapt to a modern tech stack—microservices, complex API orchestration, and rapid onboarding flows.

Core Banking System (CBS) integration

The translation layer between modern apps and legacy core systems. We test transaction state synchronization, timeout handling, and ledger discrepancy exploits.

KYC & Onboarding bypass

Nigeria requires strict tiered KYC. We test if users can manipulate API responses during onboarding to bypass BVN checks, spoof facial verification, or upgrade account tiers without valid documents.

Virtual card provisioning

Testing the logic around card creation, freezing, and limits. Can a user create infinite cards? Can they bypass the funding check during creation?

Cross-user data leakage

In highly interconnected apps (e.g., peer-to-peer transfers, contact syncing), we test for IDORs that expose user balances, full names, transaction histories, or phone numbers to unauthorized parties.

Example finding

KYC Tier Upgrade Bypass

The mobile app properly blocked high-value transfers for Tier 1 users. However, the API endpoint for confirming a Tier 3 upgrade accepted user-supplied parameters without server-side admin validation, allowing any user to artificially upgrade their own limits. Fix priority: immediate.

Testing the entire surface

We review everything from the iOS and Android applications to the internal admin dashboards where your customer support team accesses sensitive customer records.

Ensure your digital bank is secure from onboarding to ledger.
