|
|
I found this neat game called Perspective (from DigiPen, Google it), and I wanted to see what could be modded. I looked in its files, and found that pretty much all of the game's data was stored in standard formats in a renamed ZIP file called Default.bin. But when I tried to extract it, I found that for some reason they decided to encrypt it.
I tried extracting the strings from the EXE and using that in a dictionary attack, but I don't think it worked (though it's possible I did something wrong.) So I fired up IDA Pro and found the point where it reads the files. I haven't found any kind of password or encryption key, but I did find a point where all the files are loaded into memory. By setting a breakpoint at a certain point in the program, it's possible to find an address where later on in the program each file is extracted to, only to be overwritten by the next file later.
So I wrote a Lua script to try and capture these files in memory as they are extracted and save them unencrypted. But for some reason, every time I execute it, Cheat Engine just hangs and I have to quit it from Task Manager. It seems to be createProcess that causes this to happen, as if I only execute lines 10 and 11 (see below Pastebin post) the same thing happens. Anyone know why this is happening?
You can find the script I wrote at pastebin dot com slash XA6ta1HD (which would be a link but for some reason I can't post URLs yet. Blame the admins.)
Also, if anyone wants to try and figure out the password themselves, that would be greatly appreciated too!
I still don't know why they encrypted it...

Make sure you use the windows debugger interface, and that you're using CE 6.3 (it fixes the break on entry bug)

Ah, I'm using 6.2. Thanks; let me upgrade and see if that fixes it!
