BOLA Is The #1 API Vulnerability. We Find It Before Attackers Do.
API Security Testing finds vulnerabilities in your REST, GraphQL, and SOAP endpoints — the backbone of your mobile apps, web applications, and microservices architecture.
APIs are the most attacked surface in modern applications because they expose business logic directly. Unlike web applications where the frontend can hide some complexity, APIs lay bare the entire data model, authentication mechanism, and business workflow. A single broken API endpoint can expose more data than every other vulnerability combined.
BOLA (Broken Object Level Authorization) — where an API lets you access someone else's data by changing an ID parameter — is the number one API vulnerability globally. We have found BOLA in Indian banking apps, healthcare portals, e-commerce platforms, and government services.
APIs expose your business logic directly. A single broken endpoint can expose more data than a web application vulnerability ever could.
In our experience testing Indian applications, we have found APIs that exposed lakhs of user records through BOLA, allowed unlimited money transfers by bypassing server-side amount validation, enabled complete account takeover through broken authentication, leaked sensitive data including Aadhaar numbers through excessive data exposure, and allowed brute-force OTP attacks due to missing rate limiting.
For Indian fintech and e-commerce companies, API security is particularly critical because your payment flows, user authentication, and transaction processing all run through APIs. A vulnerability in a payment API is not just a security issue — it is a direct path to financial fraud.
Every API Security Testing engagement with Verentix delivers concrete, actionable outcomes:
We start by reverse-engineering your API — not relying on documentation. We discover endpoints, understand data models, and create custom test cases for YOUR specific APIs.
For Indian applications, we pay special attention to UPI callback APIs, payment gateway integrations, Aadhaar verification endpoints, and any API handling financial transactions. We understand the specific attack patterns targeting Indian payment infrastructure.
Our API testing methodology goes beyond OWASP API Top 10. We test for GraphQL-specific attacks including introspection, batch queries, and nested query DoS. For REST APIs, we test every HTTP method on every endpoint with every user role — a systematic approach that finds the vulnerabilities automated tools miss.
API Discovery (Day 1-2): Map every endpoint through traffic analysis, reverse engineering, and documentation review. We find the endpoints your team forgot about.
A UPI payment app had their entire transaction history API vulnerable to BOLA — accessing any user's payment history by incrementing the user ID parameter. This affected 20+ lakh transactions and the full payment history of every user on the platform.
An insurance aggregator had their GraphQL API exposing its entire schema through introspection, including internal admin mutations that allowed creating, modifying, and deleting policies without authentication.
A digital lending platform's loan approval API had no server-side amount validation — an attacker could modify the approved loan amount in the API request, potentially disbursing amounts far exceeding the approved limit. The potential exposure was estimated at ₹1.2 crore per day.
