API exploitation refers to cyberattacks that target Application Programming Interfaces (APIs) - the software bridges that enable different applications to communicate. Attackers exploit vulnerabilities in these APIs to access sensitive data, disrupt services, or perform unauthorized actions. As APIs are widely used in modern software and cloud services, their security is crucial. Common API exploitation techniques include manipulating requests, bypassing authentication, and injecting malicious code. Protecting APIs involves strong authentication, input validation, and regular security testing.
