odex-patcher
A tool for executing arbitrary code on Android by patching OAT files while preserving the original app signature.
What is odex-patcher?
ODEX Patcher is a tool for Android that allows developers and researchers to run arbitrary code by patching OAT files, which are Ahead-of-Time compiled artifacts created by the ART runtime. It solves the problem of executing custom code in apps that use signature verification mechanisms like SafetyNet, where traditional modification and re-signing would be detected and blocked.
Android security researchers, reverse engineers, and developers who need to modify or analyze apps on rooted devices, particularly those dealing with apps that employ integrity checks.
It provides a method to inject code while preserving the original app signature, enabling bypass of security measures like SafetyNet without detectable repackaging, which is not possible with standard Android modification tools.
