CodeGate CTF 2011 : Binary - 100 Points
File given to us:
This is the original file:
Windows Script Decoder (http://www.virtualconspiracy.com/index.php?page=scrdec/intro) - Decode encoded stuff by Microsoft Script Encoder
Analysing the File:
Using file and TriD and i cannot correctly identify what is this file. Then i opened up in Notepad++ and i find it familiar.
Thank goodness i'm a fan of Yosuke Hasegawa and i saw that this file bears resemblance to his jjencode (http://utf-8.jp/public/jjencode.html)
Ok, now i may be on the right track that this file may be encoded with jjencode...so how do i decode this? :(
I started googling for a decoder and i found this website (http://www.e-x-e.dk/2011/07/28/jjencode-decoder-jjdecode/).
But sadly it couldn't work for this. :(
Solving the Puzzle:
Finally, after several hours. i found this, Microsoft Script Encoder (http://www.microsoft.com/download/en/details.aspx?id=3375).
Could it be using this? So instantly i googled for the decoder for this and i found this useful tool, Windows Script Decoder (http://www.virtualconspiracy.com/index.php?page=scrdec/intro).
