To perform security testing different tools are available in order to be able to manipulate requests and responses, decompile Apps, investigate the behavior of running Apps and other test cases and automate them.
The MSTG project has no preference in any of the tools below, or in promoting or selling any of the tools. All tools below have been verified if they are "alive", meaning that updates have been pushed recently. Nevertheless, not all tools have been used/tested by the authors, but they might still be useful when analysing a mobile app. The listing is sorted in alphabetical order.
