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 is the timeline for a Backend Development project?
Depending on the size of the application or network, it takes 5 to 20 business days on average.
What do we receive at the end of the test?
PoC evidence showing exactly how vulnerabilities are exploited, remediation code, and an executive summary for C-Level management.
How do you ensure data security during the test?
All tests are performed under a strict NDA with the principle of least privilege, and all logs are securely wiped post-engagement.
