iCTF2011. Challenge 33 ($100)

There is file “reverse5”, but if you look at that, you don’t see executable file at all. It is some “binary trash”. Size is 991117 bytes and it looks like a packed one (large entropy).

But if you open file in hex editor (Hiew for example) and “Page down” a little you will see part of file where entropy is smaller.

Ooo! There is a JPEG signature here “JFIF”, bingo!
