| Kirjava Author 20. Feb 2014 | Well done! You are one fast reverser! I guess I set the difficulty a bit too high or maybe you are just awesome. Probably both. |
| demoth 21. Feb 2014 | Kirjava, the most difficult part is function 0xE71170 after that just break on 0xE71010 and see why fall. Total 3.5 hours. Some checks after "obfuscate" make analysis of 0xE71170 easier. |
| fine 01. Mar 2014 | well,it handsome |
| adwi32 20. Mar 2014 | its kinda hard. I guessed 1 byte of password only :D I know whats going on but i cant figure out how to guess the more letters. Looking forward for tutorial. |
| adwi32 29. Mar 2014 | wow, good job bike. I had tunnel vision on the code morph function and tried to guess all letters only using this function. I havent even look deeply in "NOPE!" functions, I thought its non-important. Because why would it be? The program main flow just checks lenght, and last char of the password, and if thats ok, it goes to code morph function. So if thats non-valid, what is point of checking particular letters in "bad boy" function, its wrong anyway? |
