Needle is a decommissioned open source modular framework designed for conducting security assessments of iOS applications. The tool was originally developed to work with iOS 9 and iOS 10 systems, providing security professionals with a structured approach to iOS app testing. Needle's modular architecture allowed users to perform various security assessment tasks on iOS applications through a systematic framework. The tool became non-functional with the release of iOS 11 due to changes in the iOS architecture and security model. F-Secure, the organization behind Needle, discontinued maintenance and development of the project. As an alternative, F-Secure recommends using Objection, which provides similar functionality for iOS security assessments and remains actively maintained. Needle is no longer suitable for current iOS security testing requirements due to its incompatibility with modern iOS versions.
