I fired up gdb, added some breakpoints before and after the first input string required for the bomb. Then I stepped through the disassembled instructions to find a function called phase_1. Note that between the beginning and end of phase_1 there is a call to the function strings_not_equal. So we have two options … See more We can start by disassembling the phase_2 function just like we did for phase_1: While the read_six_numbers function hints that … See more I restarted the program in gdb, set a breakpoint at the phase_3 function, and entered the passwords we’ve found so far for phase 1 and 2. … See more Let’s look at the first chunk of the disassembled phase_5function: Notice the call to the string_length function, and the resulting jump away … See more Lets disassemble the phase_4function next.
