Application 3 **BROKEN**

It is highly suggested that you complete Basic missions before attempting Application missions.

If you need help with this mission, make sure you have a legitimate question. Questions like, "How can I find the password?" or "Where do I find the string?" is UNacceptable. Why? Because a.) You're stupid. b.) You obviously want to be spoonfed BECAUSE you're stupid or c.) You want to complete the mission for points because you think you can redeem them for a cheeseburger at McDonalds. I'll tell you what - below is a list of what you may need to know to complete many Application missions. Please note, not all are necessary to complete this particular mission.

In the end, we hope you do learn. That is the point of being here on HTS.

Knowledge May Be Required:
- Code Analysis/Hex-Editing
- ASM Knowledge
- Compiled Languages (i.e. C/C++, VB)
- Interpreted Languages (i.e. PHP, Perl)

Useful Tools:
- Ollydbg
- Decompiler

** P.S. Posting answers and/or spoilers (i.e. mission links, mission file names/gages, scripts/code) will DEFINITELY result in multiple warnings/bans.

The End.

Hi,

so I found out the app3.exe looks something up and i have to "simulate" an answer to complete it.
I'm kinda new to hex-editor manipulations and i don't understand why changing -the- value directly in the hex code doesn't work.
i didn't want to spoil but i hope you got what i'm trying to ask ^^

greetz,
jP

Perhaps hackthissite.org doesn't always have to be so far from home...

I need a hint for this one. I've found the link but I don't know how to get the serial number from it.

Maybe you dont need the serial number :) I found a hex editor to be the only tool i needed for this mission. Although for linux users wine comes in handy if you cant be bothered with virtual box etc. wireshark could be usefull too if you like

I've simply solved the app 1 and 2 opening the .exe files with the notepad.

I just got no clue what to do in 3, any hints?
