Help decryption on binary file. [GoldenChicken]

Post by PikabobAlex »

Hello guys, can anyone please help on decryption of this binary file? I've been using many tools like rar, 7z etc to open the file, even using QuickBMS with all available script for .bin to extract the file but failed.

GoldenChicken_0.bin is for sure flip, the first byte is the last one and so on, that's visible due to the "UnityWeb" magic. Try this script:

Code: Select all

get NAME basename
get SIZE asize
encryption reverse ""
log NAME 0 SIZE
I don't know what should be the content of the other bin files since it look all random data, maybe they are encrypted for real.

THANKS, your script is work! every single files is flipped all I did is just flip it back and concatenating them back into one file.

And aluigi, the mercury format file i sent you last time, is it really no way to extract the rest of the files?

You are OT and I don't know about what you are referring, my http://aluigi.org/bms/aristocrat_mercury.bms script works perfectly.

At the end of the extraction quickbms gives you a "coverage" information with the percentage of input file that has been parsed, if you get a value higher than 90% or 95% there is nothing else inside the archive to extract.
So what you got is all the data available.
