objectionis a runtime mobile exploration toolkit, powered by Frida. It was built with the aim of helping assess mobile applications and their security posture without the need for a jailbroken or rooted mobile device.
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.
objection, you are still limited by all of the restrictions imposed by the applicable sandbox you are facing.
For all supported platforms,
objection allows you to:
- Patch iOS and Android applications, embedding a Frida gadget that can be used with
objectionor 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
.plistfiles 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.

A sample session, where
objectionversion 0.1 is used to explore the applications environment. Newer versions have the REPL prompt set to the current applications name, however usage has remained the same:
objection, all you need is the python3 interpreter to be available. Installation via
pip should take care of all of the dependencies needed. For more details, please see the prerequisites section on the project wiki.
As for the target mobile applications though, for iOS, an unencrypted IPA is needed and Android just the normal APK should be fine. If you have the source code of the iOS application you want to explore, then you can simply embed and load the
FridaGadget.dylib from within the Xcode project.
Installation is simply a matter of
pip3 install objection. This will give you the
