AI Security Lab released a diagnostic tool designed to combat App-to-Backend (A2B) attacks. These attacks involve analyzing Android applications to identify vulnerabilities in connected APIs and backend servers, such as authentication flaws or configuration errors, which can lead to unauthorized access or data leaks.

Security experts, including the National Institute of Information and Communications Technology (NICT), have warned of an escalation in these threats. The NICT noted that while the focus is often on Android, iOS apps and web services are also susceptible to these methods, which can result in massive data breaches even when the mobile application itself remains secure.
