Challenge Description
Can you figure out what is in the eax
register at the end of the main
function? Put your answer in the picoCTF flag format: picoCTF{n}
where n
is the contents of the eax
register in the decimal number base. If the answer was 0x11
your flag would be picoCTF{17}
.Disassemble this.
Approach and Steps
Run gdb debugger0_a
to start debugging the binary.
Found this line by running dissass main
0x0000000000001138 <+15>: mov $0x86342,%eax
Converted 0x86342
to decimal and got 549698
.
