Hi guys, I have finally completed the mission.
I didn't use wireshark but the posts here suggest that it can be of help if you are stuck(do download it if you can, it will be useful for a person who visits this website).
Seems like most people are/were stuck at the c*****.*** file. The information given on that file on how should sections of it be removed was not necessary. So just think about how are variables separated on a URL and keep doing that until the end. Only worry about the first line, if you get that one right, it'll all be good.
The actual login isn't anything special so just get in.
A decompiler is needed and i used this one: http://www.showmycode.com
. It's all done online.
I hope this post helps(if i tell you more about that file, i'll spoil it).Contact me if you are still stuck. Good luck
