| truthhk 14. Nov 2015 | hi borismilner,is this level-4,only need change the jno to jo?,the carckme some code is dynamic encryption,but the key algorithm,only at the begin of the code use the password we input ,check the password is not Mario ,other where never use the password ,only use the 409000 to calulate the key and at last add 1000000,check if overflow or not |
| acruel 15. Nov 2015 | You dont need patching. |
| ranbe3 24. Nov 2015 | i can't figure out if there is a manipulation on the password, it seems like not.. patching this is very , but im not sure this is the mission any tips ? |
| Unvarying 24. Nov 2015 | Lol it checks to make sure your name isn't "Mario". Almost done, I just need to finish up the part that executes if your name isn't Mario. I saw some of it, and as I was stepping through, I noticed that the instructions were changing other instructions :o |
| batman10 26. Nov 2015 | This may be a bug in the crackme? why the number to verify the password is taken from the stack, but not from our the entered password. It turns out that the value is always the same, and does not pass the test. sorry for bad english. |
