Reverse engineering involves deconstructing a compiled or packaged application by extracting its source code or bytecode and using disassemblers or decompilers to reconstruct its logic and design. Security administrators apply this technique to mobile applications to identify hidden flaws, undocumented behaviors, and exploitable vulnerabilities that cannot be discovered through black-box testing alone, ultimately enabling targeted bug fixes and improved defensive controls.

App sandboxing is an OS-level isolation mechanism that restricts an application's access to system resources and other processes to contain potential damage, and does not involve extracting or disassembling application code.

Jailbreaking is the act of exploiting OS-level restrictions on a mobile device to gain elevated root privileges, and is not a method for disassembling or analyzing an application's internal source code or design.

Social engineering is a manipulation tactic that exploits human psychology to trick individuals into revealing sensitive information or performing harmful actions, and is entirely unrelated to extracting or analyzing application binaries.
