## AI overview

The article explains mobile app reverse engineering as the analysis of compiled binaries to reconstruct an app's logic, data flows, and structure. It describes legitimate diagnostic uses, attacker risks such as credential extraction and vulnerability discovery, why iOS and Android protections do not fully protect application code, and static analysis using tools including Ghidra and Hopper.

## Source excerpt

Reverse engineering is the process of analyzing compiled software to understand how it works, without having access to the original source code. In the context of mobile applications, it means taking a published app and working backward through its binary to reconstruct its internal logic, data flows, and structure.
