Why FinTech Are Targeted
Financial services are high-value targets for criminals. Here's why attackers focus on FinTech:
API-Centric
APIs are a key FinTech attack surface, enabling data exposure, transaction manipulation, and auth bypass when insecure.

Cryptocurrency Theft
Hot wallets, custody systems, and bridge contracts are high-value, irreversible targets. A single flaw in key handling or signing logic can drain customer funds in minutes.

Vendor and Ecosystem Risk
Payment processors, banking-as-a-service partners, card networks, fraud vendors. Every integration is another attack surface, and a compromise at the vendor layer hits your data and your reputation.

Legacy System Integration
Core banking, settlement, and mainframe systems were not built for modern threat models. The seams between legacy and modern stacks are where authentication, authorization, and data-handling gaps go unnoticed.

Common Vulnerabilities We Find
Critical
Insecure direct object references (IDOR)
Critical
Business logic flaws
Critical
Broken authentication on APIs
Session handling, token replay, and weak JWT implementations across REST and GraphQL endpoints.

Weak cryptography or hardcoded secrets
High
Missing rate limiting
High
Insufficient input validation

Compliance Requirements for FinTech
What We Test
Our penetration tests are tailored to FinTech environments, covering the systems and workflows where breaches cause the most damage.
Payment Processing & Transaction Systems
We test for authentication bypass, race conditions enabling double-spending, business logic flaws, insecure authorization, and data access leaks across REST & GraphQL APIs.
APIs & Third-Party Integrations
We identify broken authentication, excessive data exposure, missing rate limiting, token replay risks, and injection vulnerabilities affecting connected services.
Customer Account & Authentication Systems
Testing includes credential-stuffing resilience, weak MFA flows, session hijacking risks, enumeration flaws, and insecure password reset logic.
Mobile Applications
We test for hardcoded keys, insecure local data, SSL certificate weaknesses, sensitive data leakage, and bypassable biometric authentication.
