| zairon Moderator 08. May 2006 | Well, you can patch the crackme in few seconds, 13 are too much. If you have a valid serial... write a tutorial :) |
| BLODYALBO 07. Nov 2009 | Very Very Easy to crack this. Set Je to JNZ. |
| cobrasniper555 07. Nov 2009 | Uses an Rivest Cipher. I'm not sure what kind yet. However, the output is hardcoded, meaning there is only one password. I'm trying to find the key right now but once that is found, it shouldn't be too hard to find the real serial. |
| qpt^J 07. Nov 2009 | all serials with 8 chars in Base10Table has been bruteforced detection: none :) |
| cobrasniper555 08. Nov 2009 | gpt^J, I don't understand what you're saying. I detected a RC5/RC6 signature in the file. Used multiple detectors to confirm. Does he use a Base10 encryption? |
| qpt^J 08. Nov 2009 | sorry, I had to say Base10Char,not Base10Table. Base10Char - it's only nombers 0,1,...,8,9 - I used it for bruteforcing,but I don't succesful About RC5/RC6 - first part RC5 - RC5ENCAB and RC5Encrypt is modified second part is RC6 - RC6ENCRND is modified too |
| qpt^J 08. Nov 2009 | ok, first algo has solved invoke RC6Init,addr Serial,dword ptr szSerial rounds = 4 |
| cobrasniper555 08. Nov 2009 | Yeah. The first part I have the source for. I'm currently working on the second part as well. I like your Base10Char idea! =D Is the cipher 64 bits? The preceeding 8 bytes I think are associated with the key for the cipher. |
