Posted: Fri Jul 14, 2017 9:43 am Post subject: Bypassing Software registration |
|
|
Hello everyone,
First post, and I hope my post won't break the forum rules.
I've seen a few tutorials using the "Crackme" program, using "referenced strings / functions" to bypass the software registration or making it succeed.
I recently helped a friend (MD student) with his new computer and helped him install a specific (and very old) program. Since it's for his studies, he will have a paid licence by his university, good for him.
I'm not interested whatsoever in the software itself (an old program from 2003 that opens a picture and let you trace/calculate things on it for hips replacement), but i really wanted to try my newly acquired skills on CE (followed the tutorial, and made my first trainer on Sniper Elite 3 ) on this program.
I figured that since its old, it could be easy to crack, but that's absolutely not the case.
The thing is, referenced functions / strings doesn't help at all, nothing increments, and the strings have nothing to do with the program itself. I was wondering if you guys could give me clues to how the registration process could be "defeated", ideas are welcome, the result is not important.
Additional Info :
- URL : www(/dot/)ebra(/dot/)info/ebra-fca-fcagraf/ => trial version
- Windows may warn about opening the program (WIN10), don't know why, but the software comes from a austrian medical university, so it's safe to assume it's safe
- First thing you have to do is to open an image (jpg or whatever)
- Registration windows is located in the "?" menu in the menu bar
- If the registration is done, i believe "File -> Write Data" won't be greyed out anymore (not sure, just a guess)
Again, I'm sorry if it breaks any rule, I'm really not asking for a crack here. Also sorry if it's not the right section to post in.
Thanks in advance for any lead/clue.

Yeah that's what I had figured out before posting :/ at least I managed to grasp the functions that does the registration, that's a step. I was really wondering why the "referenced strings" method wouldn't work on this one.
First (and final) results :
Entering dummy information in the registration process
Find out what accesses the fake licencing key i entered...
There are about 300 functions called simply by clicking "register" and most of them are calls to external windows DLL :'( Even though the post breaks the rules (again sorry about that), I see it would have been too big of a challenge for me.

Why are you using CE for this? Anyway, this type of discussion is prohibited here.

Dunno, I've watched every tutorial available about crackme software and CE, had a software nearby with a registration process, was worth a try I guess
