Lending platform security testing

Why lending apps lose money to hackers

Lending platforms are massive targets. You give out cash. Hackers want cash. They do not want to steal data to sell later. They want to exploit your logic and drain your capital today.

Most lending apps fail because they trust the user too much. The app asks the user for their salary. The app asks the user for their BVN. The app trusts the answers. Hackers intercept the network traffic. They change the answers. They trick your backend server into approving a massive loan for a fake identity.

Automated scanners cannot find these logic flaws. A scanner checks if your server uses old software. It does not check if a user can borrow ten million Naira using a stolen ID. We act like real hackers. We hunt for the fatal logic flaws that destroy lending businesses.

The anatomy of a lending platform attack

Hackers exploit the gap between your frontend app and your backend server. They download your Android APK. They use tools to bypass your SSL pinning. They connect the app to a proxy tool like Burp Suite. Now they see every single piece of data your app sends to the server.

The hacker clicks "Apply for Loan". The app sends a request to the server: `loan_amount=50000&credit_score=400`. The hacker stops the request in the proxy tool. They change the data. They rewrite it to: `loan_amount=5000000&credit_score=850`.

They forward the tampered request to your server. If your server does not recalculate the credit score independently, it approves the loan. The hacker gets the cash instantly. They delete the app and disappear.

This is exactly how lending platforms lose millions in a single weekend. We test your APIs to ensure your server never trusts the frontend data.

What we test in a lending security review

We perform deep, aggressive testing on your entire lending infrastructure. We test the mobile app, the web portal, the APIs, and the admin dashboard. We cover every angle.

Loan origination logic flaws

We attack the core engine of your business. We change the loan amount parameter. We change the interest rate parameter. We try to inject negative numbers to see if we can trick the system into paying us to borrow money. We find every gap in your mathematical logic.

KYC and identity spoofing

Hackers use stolen identities to get loans they never intend to repay. We test your integration with third-party identity providers. We use fake BVNs. We upload fake ID cards. We try to bypass your video liveness checks using deepfakes and pre-recorded videos. We force your system to reject fake humans.

Repayment manipulation

We test the repayment flow. If a user owes 100,000 Naira, we try to pay 1 Naira and intercept the success callback. We change the callback message to tell the server we paid the full amount. We test your integration with Paystack, Flutterwave, and direct bank transfers. We ensure nobody can fake a loan repayment.

Broken Object Level Authorization (BOLA)

Lending apps hold highly sensitive data. You store bank statements, ID cards, and home addresses. We test every API endpoint for BOLA. We log in as User A. We change the user ID parameter in the URL to User B. If your server gives us User B's bank statement, you have a critical data leak. We hunt down every BOLA flaw.

Admin portal vulnerabilities

Your internal admin portal is the keys to the kingdom. We try to bypass the login screen. We try to steal admin session cookies. We check if an attacker can manipulate a customer service agent into clicking a malicious link that grants the attacker internal access. We lock down your back office.

The tools we use to break your app

We use the exact same toolchain that advanced financial hackers use to break into lending platforms.

• Frida and Objection: We hook into the live memory of your iOS and Android apps. We bypass SSL pinning. We bypass jailbreak detection.
• Burp Suite Professional: We route all mobile and web traffic through Burp. We intercept and modify every single loan request before it hits your backend.
• Jadx and Ghidra: We decompile your Kotlin and Swift binaries. We read your raw code to find hidden API endpoints and hardcoded encryption keys.
• Custom Python Scripts: We write bespoke Python scripts to exploit complex race conditions. We test what happens when a user clicks "Withdraw" fifty times in one second.

The final delivery and remediation process

We do not just find the bugs and walk away. We give your engineering team the exact tools they need to fix the code quickly and permanently.

You receive a massive, detailed technical report. We rank every vulnerability by risk level using the CVSS framework. We provide the exact HTTP request logs. We write out the exact steps to reproduce the attack. Your engineers can copy our steps and watch the bug happen on their own screens.

We give you precise code snippets to fix the flaws. We show you how to implement strict server-side validation for all loan amounts. We show you how to secure your webhook endpoints. We show you how to enforce robust database row locking to prevent race conditions.

We jump on a video call with your developers. We explain the risks plainly. We answer every question. After you deploy the fixes, we retest the application to prove the bugs are gone. We issue a clean security certificate.

Regulatory compliance and data privacy

Lending platforms face massive regulatory scrutiny. You collect BVNs. You collect bank statements. You collect home addresses. If you leak this data, the government will fine you heavily.

We map every single vulnerability we find to the major compliance laws. We map our tests to the NDPA (Nigeria Data Protection Act) rules. We map our tests to the CBN cybersecurity guidelines. We map our tests to the OWASP Top 10 standard.

Our Head of Compliance Oversight reviews your final report. We ensure the document satisfies your banking partners, your investors, and your regulators. You prove that you take customer data privacy seriously. You close your funding rounds faster. You operate without fear of catastrophic fines.
