Binary Bomb in 32bit NASM Assembler

I have a binary bomb that has 6 phases that need to be defused. The bomb is an executable that has been dumped and the assembly is 32bit nasm. Each phase requires a codeword to get to the next phase. The project is a test of the use of the GDB debugger as the codewords are hidden inside the registers.

Budget is 50USD

Will not accept anything above
