Penetration Testing
for Banks
Bank Penetration Testing by Researchers With 150+ Published CVEs and 10 Years of Experience Testing Financial Institutions
Bank Penetration Testing That Reduces Risk
Why most bank penetration testing fails to reduce risk:
Development teams get reports they can't act on
Security leaders spend weeks arguing about priorities
Boards receive technical documents without business context
We show you what breaks, how it breaks, and what customer data is exposed
Why Banks Choose AFINE for Penetration Testing
We've spent 10 years penetration testing major European banks in production and found hundreds of critical vulnerabilities. You get researchers who know what breaks in core banking infrastructure, and reports that show exactly how we exploited your environment. Each finding includes working proof-of-concept and business impact.

Our Services
What We Cover in Bank Penetration Testing
Digital Banking Platforms
We manually test authentication and authorization mechanisms across different user types. This includes reviewing cryptographic implementation and password handling practices. We analyze business logic in transaction processing to find flaws that compromise financial operations.

Mobile Banking Apps
We reverse engineer applications to understand actual behavior versus documentation. Test data storage, crypto implementation, and traffic interception. Verify security on jailbroken/rooted devices. Authentication and authorization across different device states.

Payment and Transaction APIs
We enumerate endpoints and test authorization boundaries between users and transactions. Analyze transaction flows under concurrent load for race conditions. Check business logic flaws specific to financial transaction processing. Test API authentication and rate limiting.

Core Banking Systems
We simulate breach scenarios from internet-facing systems to core infrastructure. Test network segmentation, privilege escalation paths, database access controls, and administrative interfaces. Review source code for custom banking applications - memory corruption, type conversion issues, race conditions, and architectural problems only visible by reading code.

Third-Party Integrations and Operational Technology
We assess security at integration points and trust boundaries. Test authorization across partner connections, SWIFT messaging security, and network segregation. Evaluate OT infrastructure including building systems, security cameras, and access control. Check whether IT and OT networks are actually segregated and if physical security systems have digital vulnerabilities.

ATM and Hardware Security Testing
We test physical devices and embedded systems. Analyze ATM firmware, payment terminals, HSM configurations, and NFC/RFID protocols. Test for backdoors, unauthorized code, communication protocol vulnerabilities, and resistance to physical attacks. Hardware compromises persist longer than software bugs.

Social Engineering Testing for Banks
We run spear phishing against privileged users, phone-based social engineering, and physical access attempts. Insider threat simulations show what happens when legitimate access gets abused. Test employee awareness with realistic scenarios specific to banking operations and actual user access levels.

The Enterprise Security Software We Hacked
Our bank penetration testing discovers vulnerabilities in the platforms that major banks depend on. We exploit both known CVEs and the vulnerabilities nobody's documented yet.

Memory corruption in Microsoft Edge (EdgeHTML) allows remote code execution via crafted web content





SQL injection in F5 BIG-IP AFM (Advanced Firewall Manager) allows database attacks on security appliance
