Background for this topic.
Application Programming Interfaces (APIs) are sets of rules that allow software applications to communicate and exchange data, often enabling functionality across different systems or services. APIs define how requests and responses are structured, making it possible for programs to interact without direct user involvement. In cybersecurity, APIs are commonly exposed over networks as endpoints that handle sensitive operations like data retrieval, user authentication, or transaction processing.
APIs increase the attack surface by exposing endpoints that attackers can target with unauthorized access attempts, injection attacks, or denial-of-service. Common risks include weak or missing authentication, insufficient input validation, and improper rate limiting. Effective API security requires strong authentication protocols (e.g., OAuth), strict input validation to prevent injection, rate limiting to mitigate abuse, and comprehensive logging to detect anomalies. Protecting APIs is critical to prevent data leaks, privilege escalation, and service disruption in interconnected environments.
A new "comprehensive toolset" called AlienFox is being distributed on Telegram as a way for threat actors to harvest credentials from API keys and secrets from popular cloud service providers
The emergence of smart mobility services and applications has led to a sharp increase in the use of APIs in the automotive industry. However, this increased reliance on APIs has also made them one of the most common attack vectors. According to Gartner, APIs account for 90% of the web application attack surface areas. With no surprise, similar trends are emerging also in the smart mobility
