Program Hides Secret Messages in Executables
DmuZ writes "My friend Rakan has created a new steganographic tool named Hydan which can embed messages into an executable without altering its size. He recently presented this tool to the public for the first time at codecon. This new technique was intriguing enough to get coverage on SecurityFocus.com. The code is available here."

so how do i add my 6MB ogg to the 526K ls?

I don't know about you, but where I come from all bytes are pretty much 8 bits in size.

Altering the value of a byte changes its size?
Man, I need to get me some of them new magic size-changing bytes! Down with the tyranny of 8-bit bytes!
...but why?
Why would I want to hide messages in my executable files?
Because I'm a secret little squirrel who just in general likes to hide stuff, like INSIDE other stuff?
Surely, a declaration of independence should be stored in a non Microsoft product.

:/
On second thought, I have another idea: make a huge file that is nothing but stenographic data. Hide an executable in it.
Actually, for stuff like DeCSS, that may not be so farfetched.
~REZ~ #43301. Who'd fake being me anyway?
I hide all sorts of stuff in my C comments.
Nobody can detect them in my executables.
HA! I'm so sneaky!
Moneyed corporations, non-working 'poor' and criminal prisoners are turning productive citizens into tax-slaves.
