hey guys

i am quite familiar withi assembler, and i had a very lose look at the Application with OllyDbg, IDA and DASM, but i just can't find out where the input is validated...
i also looked into the scanf and printf subroutines, but i assume that these are just predefined C functions...

the comparison, where the program decides whether to show good pass or bad pass only compares zero to CCCCCCCC, no matter what i input.

i am pretty much stuck right here and will appreciate any kind of help

thx!

okay, i had a closer look to the subroutines and i single-stepped through everything that was not pure system code...
what do i miss? oO
i know i must be close but i can't get to any solution

ollydbg is the right tool for this level.

search in olly for the string "nic3 , the password to this crackme is the same password in the submit scor" in order to find where the input is validated.
