Improper Credential Usage

Overview

Improper Credential Usage is a cybersecurity threat wherein threat agents exploit hardcoded credentials and engage in improper credential usage in mobile applications. This vulnerability can lead to unauthorized access, data breaches, loss of user privacy, fraudulent activity, and potential access to administrative functionality.

Description

Improper Credential Usage is a prevalent security weakness that can be easily exploited by adversaries. It can occur when hardcoded credentials or improper credential handling are present in mobile apps. This vulnerability allows attackers to gain unauthorized access to sensitive functionalities of the mobile app, bypassing the need for legitimate access. To prevent Improper Credential Usage, it is important to avoid using hardcoded credentials and properly handle user credentials. User credentials should be securely stored, transmitted, and authenticated. Regularly updating and rotating API keys or tokens is also recommended.

How to Prevent ?

To prevent Improper Credential Usage, follow these best practices: 1. Avoid using hardcoded credentials in mobile app code or configuration files. 2. Encrypt credentials during transmission. 3. Do not store user credentials on the device; instead, use secure, revocable access tokens. 4. Implement strong user authentication protocols. 5. Regularly update and rotate API keys or tokens.

Example Attack Scenarios:

• Hardcoded Credentials:  An attacker discovers hardcoded credentials within the mobile app’s source code. They use these credentials to gain unauthorized access to sensitive functionality within the app or backend systems.

• Insecure Credential Transmission:  An attacker intercepts insecurely transmitted credentials between the mobile app and its backend systems. They use these intercepted credentials to impersonate a legitimate user and gain unauthorized access.

• Insecure Credential Storage:  An attacker gains physical access to a user’s device and extracts stored credentials from the mobile app. The attacker uses these credentials to gain unauthorized access to the user’s account.
