Embedded devices, which are essentially microcomputers of chip size, have become an integral component across various objects they control, including but not limited to phones, automobiles, credit cards, laptops, medical equipment, and even pillars of critical infrastructure. The omnipresence of these devices underscores the importance of comprehending their security landscape.

We all know that APK is actually a compressed file package, so we can extract the files directly from the APK file using the file decompression software like 7-Zip, WinRAR. However, the XML files in the source files obtained in this way are encrypted and cannot be directly viewed. So we need to resort to some specialized APK decompilation tools.

Noesis is a very powerful and easy to use universal game data unpacking tool, created and maintained by Rich Whitehouse. It is mainly used to preview, convert and extract/export (reverse engineer) all kinds of 3D resources/assets from PC and video games, and considered to be one of the must-have tools for making game MODs (Ninja Ripper is another).

Packing a program is the most common way developers protect their software. Therefore, in order to crack some software, the first step is to detect whether it has been packed. Detect It Easy (DiE for Short) is a very powerful and easy-to-use PE packers detection tool developed by horsicq from Germany. It has very comprehensive and functional PE packer detection functions, simple operation, and is widely used as one of the most important auxiliary tools for software cracking for now.

In the current Internet environment, most commercial software can be cracked, and that is just a matter of cost and time at most. In order to protect their software from reverse engineering or cracking, almost all software developers use a lot of codes with complex encryption algorithms. That not only costs developers a lot of energy and expense, but also makes the program more chaotic and bloated, and the final effect is not obvious.
