Stego 5

I am having problems finding all of the data. i know how it is stored (a different one out of three) but i can not seem to find all of them and interpret them correctly. I tried a program that compares groups of three, but all i got were sets of three that were staggered so that the last value of one set is the first value of the next and the last of that group is the first of the next ect. Please help.

It sounds like you have the right data, it's just a matter of interpreting it at this point. Correct me if I'm wrong, but it sounds like you're attempting to consider only the values that are different. That's a fairly good assumption, and I'm sure a lot of us jumped to that conclusion at first, but that's not going to get you the answer. Instead, focus on how all the values of the pixels of interest differ from one another.

Here's an example to illustrate what I mean. If you have something like so...

Code: Select all: 0x44 0x45 0x45 0xa2 0xa2 0xa3 0x88 0x89 0x88

Your first thought may be to take 0x44, 0xa3, 0x89, and begin constructing your answer from that. That's not a bad assumption, but it's not the correct one in this case. Look closer. Consider the entire set of values. There's a logical pattern to which ones are different. Find that pattern, and you'll be at the final step. If you're having trouble seeing it, maybe it's because you're thinking in groups of three. Try grouping them differently, see if that helps.

I believe that this has something to do with a very simple number system one with only 2 ( or 10

) numbers. is that close?

It's not far.

Play around with what you get. Don't be afraid to experiment.

The end was a bit confusing but i got it. Thank you for your help.

Ok, so I've gotten to the point where I can see the bits, and I've tried translating them, but they won't go through the translation because I'm missing 1(or 0) somewhere.

It only took me about 20 minutes to get this far, but now I've been here for an hour and a half trying to see past it.

Any hints?

do i have to learn about TCP 3-Way Handshake, iptables and stuff for this mission?
coz i got something like ***-***-* , but thats not the answer, right? i tried to add sh at the end just to make more sense, replaced - with / and space, but no cigar. Any advice?
EDIT: seconds after this post i did it! google suggestions are useful sometimes.

So before anyone thinks that they do: no, that's not needed. But still, you'll find that knowledge useful for other challenges on this site.

I've gotten the first part of the password, but I can't find how to get the last 3 letters. The pattern ends before there's any more to it. Can anyone give me a hint on how to get the last part?
