Okay, my exams are going on and today is one, so I may not be able to participate in this challenge, just may be. But a quick gives information like below:

The length of serial will be 32


8'th alphabet must be a -
This crackme will raise an exception for instruction REP MOV
The correct serial will form string "Tron : Legacy" and may be the goodboy.

 

Hopefully will back to solve this soon.

 

PS:

PeterPunk good job!

The length of serial will be 32 ---> agree with you

8'th alphabet must be a -----> I think 1st char should be 'a-z' :P

 

Serial format should be "XXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXX"

I call it's "part1-part2"

 

The first check is CRC32. If CRC32(Part1) = 59E25558 (hex) then you pass the first check

 

The next check may be 3way and base on part1 and part2. That's mean with invalid part1 you will get invalid part2

 

But all of them direct you to a MessageBox which shows nothing. Why????????? 

Did I miss something........?

Yes, it should be! Because after the check of length (32) the next check is check for value of 8'th alphabet.

CMP BYTE PTR DS:[4095F3],2D

Then in the call @ 00401035 to 004010D6 have check for initial alphabet of the serial ranging from a to z (small).

Btw, will look into :)

 

Thanks

@Blue: I didn't read carefully sorry :). So you mean 8'th alphabet must be a "-" :)
