B4R Question Compiled Arduino sketch secured?

[Beja]

Hi
Android APK is an archive file and not 100% secure against hackers...etc.
Is this the case in Arduino also or it's compiled to binary file like exe files?

the sketches are compiled by avr-gcc into a binary file depending on your hardware platform
The .hex file is the final output of the compilation which is then uploaded to the board.
