Authentication Flaws represent weaknesses in how an application verifies the identity of users or systems. These flaws can allow attackers to impersonate legitimate users, bypass login mechanisms, or exploit trust relationships between applications. Strong, server-side authentication is critical to maintaining the integrity of user sessions and protecting sensitive functionality.
Our testing methodology examines the implementation and robustness of authentication mechanisms, ensuring that identity verification cannot be easily manipulated or bypassed.
Authentication Flaw Tests:
Using Insecure Authentication Vectors (IMEI, MAC, etc.)
Tests whether the application relies on easily obtainable or spoofable device identifiers—such as IMEI numbers or MAC addresses—for authentication, which can lead to unauthorized access if exploited.
Cross Application Authentication
Evaluates whether authentication data or tokens are shared or trusted between applications without proper validation, allowing malicious apps to impersonate trusted ones.
Local Authentication Bypass Threats
Checks for weaknesses in local authentication methods (e.g., device PINs or biometric checks) that can be bypassed through reverse engineering or device compromise.
Client-Side Based Authentication Flaws
Assesses if authentication logic is incorrectly implemented on the client side, making it vulnerable to tampering, replay attacks, or complete bypass via code manipulation.
Client-Side Authorization Breaches
Tests whether authorization checks—such as role-based access control or feature-level permissions—are enforced only on the client, enabling attackers to gain unauthorized access by manipulating app behavior.
