So now that we have both keys, and both locks, what are some programs that can decode them? Someone posted a link to JRStegano, but I haven't the slighest clue how to use it.


1. It's very simple to use actually, and I tried it. No dice.
2. It's in German, anyway.
3. It's very finicky about working or not (at least on my computer).

That does seem to be the only readily available steganography decoder that accepts PNGs as input, though.

Ad Arcana Tutanda, do you know anyone that might be able to help us with this (considering you do this for a living)?


I know a bit of steganography, but I'm by far not an expert in it.

attached are some resources I have bookmarked.

In all honesty, I'm just trying to guide this in the right direction. As I know some of the tricks of this already, I firmly believe that as this being many of your first times with an ARG that I give you the tools to do so and know what it's like to discover things on your own. As I'm posting semi IG in here but mainly OOG, I just want to be a conduit to our success.

This particular link shows a method of hiding messages in JPEGs... perhaps we shouldn't rule JPEGs out?

this is true; however, our guidance was to stick to lossless files, remember?

Let's not get sidetracked. I attached the new .png file, all we have to do is unlock whatever is inside of it. :]

 		Remember, let us not get sidetracked.

This is the EXACT guidance we were given:

Quote:
Please have your group follow the directives passed down to me to the letter.


We have the new lock. Now lets break it.

Quote:
1. IF kitsune.png is the first lock, where is the other?

2. Have members conducted a thorough search for another image?

More specifically, have they investigated the history of these supposed ancestors enough to be sure that the terrorists have not hidden a second image somewhere related to these topics?

3. Lastly, have members truly considered the full range of steganographic tools that might have been available to both the senders and receivers of these messages, taking into account their probable hardware systems?

 		I think Dubrovin's mention of hardware is significant. What stenography methods are based on specific hardware or only function on specific systems (i'm thinking a specific operating system macos/linux/unix)

That's the only thing I can think of, but even then, that isn't hardware.

I'm guessing they must have Macs, then.

RECEIVERS, PROBABLE HARDWARE SYSTEMS. This stands out to me. Who's receiving the message? We know the Junsui are sending it, can we infer anything about their system? I think we're looking too far into things here, guys. We shouldn't assume the Junsui have access to complicated steganalysis tools that I haven't been able to find in the last half-hour.

Edit: beaten to the punch. Oh, well.

 		Yeah, I'm just gonna go ahead and assume that the Junsui do not have access to funds to go about purchasing one of these pricey stego programs, therefore it needs to be easily accessed and, of course, free.

 		maybe the clue about hardware means that the encoding/decoding system needs to be accessible no matter what hardware is being used.

like something online.

an old saying that was beaten into me early on within my career:

Keep it simple, stupid.

Note, that is in no way meant as derrogatory to any of you. Just don't miss the forest for the trees. We've done that several times before, and it's kicked our asses every time we've done that.

Let's try to avoid another facepalm if we can :]

 		there's probably a clue somewhere about what method they were encoded with.

also note "482" in the bottom left of the palace image

Well, unfiction has 3 stegonography programs linked. That's as simple as I can think. Has anyone tried the camouflage or camera/shy programs(the third one is a broken link)??
EDIT: Camera/shy doesn't seem to do PNG, and I can't get the camouflage setup file to work.

 		Guys, for the record most of the stenography programs that I've seen in the past ONLY work with JPEG images.

Then again, most of the ones I know of were written before PNG existed, so maybe times have changed.

I haven't opened every file in Fireworks (just the last one), but do keep in mind that PNGs is a file format that could be more than just a flat image. Fireworks PNGs could have layers, objects, etc... separated in them.

But, alas, the PNGs I've opened have none of that.

The one that seems the most promising right now is just a flat, one layer, one frame image. And the fact that none of them accept PNG is the problem. I'm starting to think we may not need to use a steganalysis program at all, but ought to be looking for something else entirely. I keep getting this tip-of-the-tongue type feeling, like we have all the information we need and just aren't looking at it right.
