The keys is exactly 16 bytes, so that's a 128 bit key. The data itself is exactly 900 bytes, and I can't figure out how they got an exactly round figure.. but I'm sure these numbers hold the key (pardon the pun) to solving it..


i was thinking about treating data.jpg as a rc128 encrypted file and using key.dat to decrypt it, but it's definitely a JPEG and not just a random byte stream, so i'm guessing this is wrong. i'm assuming that if the file is a JPEG, it's steganography and not straight up encryption. but i'm new to all this; is that a safe assumption?

looking at the image in gimp, almost all pixels are RGBA 0,0,0,255, except at least one 1,1,1,255 at x576 y7. don't know if that's an artifact of steg or if it's otherwise significant.

 		I am just glad that SOMEONE found a way to creatively make fun of all those "y"s in the woman's name. NO ONE should have that many damn y's in their name.

 		I'm lost in the crypto/steg department, so you guys do what you do best and I'll sit, watch, and drink lots of coffee.

 		could there perhaps be a clue in the page title? mal-adjusted emo baby seems a bit random. I wasn't in on Metacortechs the first, however, so it could just be a bit of nostalgia.

Well.. I uncovered something from data.jpg (as it was done using the method I was going to use for my first puzzle.)

Don't know what to do with the findings, tho.

 		mrbeefy, how did you get that? was that encrypted in data.jpg, or is that just data.jpg but with the non all-black pixels hilited?

 		To quote from searching the archives...

Quote:
wtf were you into?? i met your precious parents, and ... they're coming for their boy now. look, in one day i managed to get you what you've spent months slamming your head into your schoolbooks over.

god!!!!! what were YOU thinking, you mal-adjusted emo baby? you think I was the one that messed things up? you have no clue AT ALL. i said nightmare earlier and you LISTEN to me, you punk-ass, i was not kidding. bad situation. sorry is a small word for this. i am so sorry. you don't even know.

THEY'RE AFTER US, OK? THEM.

they're going to KILL me. i needed help, and then i didn't, and now there's no help big enough to cover this mess. wtf. i can't believe this. this was a game, right? this was just you, f***ing around, and there was me being better than you, EACH and EVERY step of the way. this WAS A GAME, but THEY don't care. screw you and your precious secrets.

you'd better run


From Brutus.mic - a message from Scratch to Ceasar - for more info goto here for the whole shebang (EDIT: Well, it should be but is currently offline).

I take it this means this is from Scratch - is there anything he did that we can use here? Will look...

Spriggan - It is data.jpg with all the non-black pixels highlighted - I got the same effect by up-ing the gamma balance in photo editor. I think the next step is to tabulate the pixel positions - if no one has done it already I'll have a go...

And then we pass it on to the maths people Smile

EDIT: In non virus txt form (excel on request) - there are 130 pixels!

 		You guys amuse me. Anyways, shouldn't we be recording the pixel gama data as 1's and 0's rather than coordinates?

Then there will be far too many 0's for it to mean anything. I'm not even sure if they mean anything or are they JPEG artifacts? So far I haven't been able to find a single document that explains the JPEG file structure, which is weird because I remember seeing some a while back which had examples and proper explanation.. I think we need a hint on this one.
