Reverse Engineering: Debugging in IDA

Tip: Press “D” to convert to data types on the “Source” or “arg” parameter.

(1) Set up a breakpoint on the “add” function right after the “sscanf” call on the fourth challenge.

(2) Pass all the necessary parameters to get to the fourth challenge.
(3) Review the windows and adjust the breakpoint
(4) Get into the “mov” function with the “Src” parameter and convert the value to data (press “D”). You see the passed values converted from hex to characters as “3[SPACE]k[SPACE]251.”
