A comprehensive guide highlighting the most common iOS application vulnerabilities to help developers and security reviewers improve app security.
Collection of the most common vulnerabilities found in iOS applications
This tool serves as an educational resource for iOS app developers aiming to identify and mitigate common security flaws in their code before release. Security reviewers can also use it as a reference during app assessments to ensure robust security practices are followed. It is primarily used for security training and risk assessment in iOS application development.
This guide is not a runnable tool but a reference and training material; it requires manual auditing and code review based on its recommendations. It focuses on application-level vulnerabilities and does not cover system-level or memory safety issues extensively. Users should regularly update the guide by contributing to keep pace with evolving iOS security practices.
int r = SecRandomCopyBytes(kSecRandomDefault, sizeof(int), (uint8_t*) &res);
Example of generating cryptographically strong random numbers using iOS Randomization Services.
Check for hiding code in applicationDidEnterBackground
Audit tip to verify that sensitive information is hidden or blurred when the app backgrounds.
Set UITextField autoCorrectionType = UITextAutocorrectionTypeNo
Disable auto-correction for sensitive non-password input fields to prevent caching of sensitive data.
Check for UIPasteboardNameGeneral & UIPasteboardNameFind
Audit tip to ensure pasteboard is handled securely and cleared when the app backgrounds.
