Free Scoping CallFinancial Services Vulnerability Intelligence
Banks, fintechs, and financial institutions handle the most sensitive data in the digital economy. A single compromised API endpoint can expose millions of customer records and trigger regulatory penalties exceeding $100M.
Broken Object-Level Authorization (BOLA)
API endpoints exposing financial data through manipulable object references, allowing attackers to access other customers' account balances, transaction histories, and PII.
Insecure Direct Object Reference in Payment APIs
Payment processing endpoints vulnerable to IDOR attacks enabling unauthorized fund transfers, invoice manipulation, and payment redirection.
JWT Token Forgery and Session Hijacking
Weak JWT implementations in banking applications allowing token signature bypass, session fixation, and account takeover through algorithm confusion attacks.
Business Logic Flaws in Transaction Processing
Race conditions and logic errors in concurrent transaction processing that enable double-spending, negative balance exploitation, and fee bypass.

Frequently Asked Questions
What methodologies do you use?
We base our testing on OWASP Testing Guide, PTES, NIST SP 800-115, and OSSTMM frameworks.
Can we get references from previous clients?
Due to NDA constraints we cannot share client names, but we can provide sector-specific references and case studies.
Do you test remotely or on-site?
Most tests are conducted remotely via VPN. For internal network and physical security tests, we deploy on-site teams.
