IOLI crackme0x03


Check the file.

Test the program out.

Analyze the program in GDB.

crackme0x03x is very similar to crackme0x02x but has a test function built instead of compare.

There are two ways to find the password.

  • The lines inside the orange box can be equated to give us an answer.
  • Set a breakpoint at the test function and print out the variable for [ebp-0xc]

Disassemble the test function

Run a breakpoint to find out the value of the strings.

Looks like its encrypted strings and just an obfuscation for the challenge.

Test the password
