   mistake found in the tutorial.

   snd-reversingwithlena-tutorial03.tutorial. i think there is an error in the tutorial, where nops are added starting at address 401039. it is obvious (to me) that the nops start at one previous instruction at 401034. these tutorials are fabulous. i would like to point out that to move the explanations along there is no need to keep pressing the mouse in the right corner. there is a step key at the bottom of each tutorial for moving in BOTH directions without having to exit the tutorial. i am using chrome and have enabled the SWF file to run without using the htm format. if someone has pointed out the error please ignore this essay.

    I'm hoping someone can lend me a hand. I'm working on trying to figure out a reverse engineering challenge and I'm stuck. There is no monetary reward or anything of the sort for the challenge.

This particular challenge give you an html file that is supposedly attacked and they ask what the attackers changed in the site. Upon review there is obfuscated php code appended to the end of the png file on the site and an include statement added to the html. The challenge is to find an email ad…
