Various hack me challenges posted on OSAC's facebook page (https://www.facebook.com/groups/osacchat/) with the following message
hackme1 was to know string password hard-coded in program just by using cat or strings commands.
hackme2 was to exploite buffer overflow vernability.
When given long string as password it overwrite the flag and set it as true.
And program behave as if correct password is entered.
Hackers! Are you ready to face a challenge?<br/>
This is a program compiled for linux. Which
-> accepts an integer from command line argument .
-> compares that argv with a pre-stored 4-digit integer.
-> prints a msg and returns 0 if they match
-> returns 1 if they don't match
Write a program to find that pre-stored 4-digit number(pass-pin) using brute force. PM me the code.

This attached file named 'wps' is a simple c program compiled for 32-bit Linux system which accepts 8-digit integer (passcode) as argument.
Its behaviour is similar to that of the wps(the flaw on which is exploited by tools like reaver for hacking wifi password).
It returns
-> 2 when the no passcode is provided or the provided passcode is incorrect
-> 0 when the passcode provided is correct
-> 1 when any half(lower or upper 4-digits) match
The task is to write a program/script to find the passcode.
(Message me the passcode and your code.)
