Hydan: Steganography in Executables
An anonymous reader says "Ever wanted to hide a message into an executable? Now you can with Hydan. Presented recently by Rakan El-Khalil at Defcon and Blackhat, this tool lets you embed data into an application without changing its functionality or filesize! Check it out. Use includes steganography as well as embedding a program's signature into itself to verify it's not been tampered with."
"What are you doing?"
"Oh, hydan out."
I am 1337.

it looks like the information is being hidden by a slashdotted executable.
NOOOOOOOOOOO!
Not really :)
But I'd like to make that dog downstairs stop barking.

Not only a dupe, but a link to the original story is listed on the referenced page.
Wow.
The message retrieval method should be called "Hydan Seek"
They should have put their message in the web servers executable so that when it gets slashdotted it could just shit itself and we could still get how it works.
Ironically, on the other hand, emacs has been doing this for years, without much data compression.

I thought steganography meant pictures of stegasaurs making little stegasarus.

A new virus is quickly spreading across the internet. Experts say it started at Defcon with a demonstration of a program that allows users to add a secret text to an executable file without altering it's filesize. Apparently the program also attached a message of it's own... don't run programs demonstrated at defcon!
I can count to 1023 on my hands. Ask me about #132.
I feel no anxiety about EXE files. Maybe it's because I run Linux.
Now, that "block all executables" setting that I can't turn find or off in Outlook will prevent terrorists from exchanging secret messages embedded in trojan executables that are attached to emails purporting to be great pornography!
It's not an annoyance; it's a *feature*!
Hey, I was disassembling all of my executables looking for hidden messages, and I found one. It reads "0xDEADBEEF"! Does anyone know what that means?!
