A little note on Traceme blasting

F3 Loading Traceme.exe

F9 run, the following interface appears

Guess input using Getdlgitemtexta,

CTRL + F2 rerun, shortcut CTRL + G to find the getdlgitemtexta position at the bottom of the breakpoint.

F9 Run, Popup registration interface, enter the user name Hello, serial number world.

Press Check to execute to getdlgitemtexta. Press F8 to go ahead. Note the "Information window",

The message "Stack address=0012f968, (ASCII" Hello ")" will appear.

Guess the logic of call traceme.00401340 execution judgment. Go ahead and F8 down.

Found a jump at JE short traceme.0040122e place. and the error message pops up at the end.

So guess if JE short traceme.0040122e does not happen jump may be successful.

Re-execution, in the execution to JE Short traceme.0040122e the ZF changed to 0, found not to jump.

Modify JE Short traceme.0040122e for NOP instructions. and save.
