API security challenges: Logic abuse, blind spots, and hacking a bank

The most dangerous API security attacks often exploit business logic rather than technical vulnerabilities — they use the API exactly as documented, but in ways the designers never intended. These attacks are invisible to tools that look only for known vulnerability patterns.

This video examines the security challenges that logic abuse and blind spots create, using the example of attacking a bank API to illustrate how real-world exploits work and why visibility into API behaviour — not just authentication and encryption — is essential.
