The project's name quite literally explains the approach as well, whereby runtime specific objects are injected into a running process and executed using Frida.
Note: This is not some form of jailbreak / root bypass. By using objection, you are still limited by all of the restrictions imposed by the applicable sandbox you are facing.
features
Supporting both iOS and Android and having new features and improvements added regularly as the tool is used in real world scenarios, the following is a short list of only a few key features:
For all supported platforms, objection allows you to:
- Patch iOS and Android applications, embedding a Frida gadget that can be used with objection or just Frida itself.
- Interact with the filesystem, listing entries as well as upload & download files where permitted.
- Perform various memory related tasks, such as listing loaded modules and their respective exports.
- Attempt to bypass and simulate jailbroken or rooted environments.
- Discover loaded classes and list their respective methods.
- Perform common SSL pinning bypasses.
- Dynamically dump arguments from methods called as you use the target application.
- Interact with SQLite databases inline without the need to download the targeted database and use an external tool.
- Execute custom Frida scripts.
iOS specific features in objection include the ability to:
- Dump the iOS keychain, and export it to a file.
- Dump data from common storage such as NSUserDefaults and the shared NSHTTPCookieStorage.
- Dump various formats of information in human readable forms.
- Bypass certain forms of TouchID restrictions.
- Watch for method executions by targeting all methods in a class, or just a single method.
- Monitor the iOS pasteboard.
- Dump encoded .plist files in a human readable format without relying on external parsers.
Android specific features in objection include the ability to:
- List the applications Activities, Services and Broadcast receivers.
- Start arbitrary Activities available in the target application.
- Watch a class method, reporting execution as it happens.
