Stego 1

i added one thing to the binary and got a 7 character alpha-numeric password and it looked right but it says its wrong. Am I adding something wrong?

EDIT
Ok I was adding in the wrong place. sorry to bother everyone.

edit: wait, what? Apparently I completed it but never got the message. Nevermind.

well.. what i did, is to find 2 null bytes 0000, i found it twice in the bmp body (not in the header), I deleted them, and aded another 2 null bytes at the end of the file, and I get the same image but it has a black bar on the right (where the original image was suposed to end) but i see no pass to the right of that black bar
edit:
I continued hex editing the image, even in the header, and i kind of removed that black bar, aparently no changes were made to the image, but when I compare it to the original, I find that the logo was moved to the left of the image, maby Im in the right track, but I dont see any pass yet
edit:
maybe is not that the logo moved to the left, but that the image width increased
edit:
i found and replaced all null bytes that I could, without corrupting the file, the image width didnt change since my last try, but a vertical bar apeared to de right of the image, now its kind of a glow, its like the white glow you see in some borders of the image but I still dont see any pass

That's not really the right track.....

I'm actually really confused with this mission! I managed to do 3 and 4 easy... 2 isn't image stego' so I'll have to research that, but 1 0_0 it is too hard for me... I've found 2 null bytes... I just don't know where to go from here, maybe I'mm looking too deep into it? Can someone please give me a nudge in the right direction?

Thank you

Ok so i found completed mission one and it felt great to be back in the world of bits bytes and chars but one small thing at the end bothered me. At the end i had it narrowed down to only a few choice i just brute forced the rest of the way. Since i am new i wanted to know if brute forcing was the correct way to go and if brute forcing is kosher when it is just an limited amount of choice remain and becomes educated guesses?

Thanks for your time

I am a bit curious. I played around with the missing info, moving it from here to there, and using the results as my password.
nothing seemed to be working. I never got a congratulations, but my profile now shows that I have completed the mission.
is that a glitch or did I just miss it or something?

That was a nice quest, finding the right place for the lost thing was the thing, one has to have good intuition to find it, however you shoud get a bit more points for this challange

Ok.. so after solving this one I have to say
i found no logical reason for that position to be the position he missed...
If anyon eknow a logical reason for that i would love to know (please PM me thanks)

You're not supposed to need brute-forcing there.
Tiksi (the one who made the mission) simply made a mistake and forgot something. Yet, he didn't forget it randomly, but in a certain place - no brute-forcing required, at least none that needs you to write an app for it.

Well I ended up brute forcing it and completed the mission pretty easily. I still don't understand how could I do it without brute forcing, the place that the missing something was supposed to be in doesn't make any logical sense to me and seems like it was chosen randomly.

You're right, it's not a logical position, but it's definitely not very difficult to add bits to the starts of each byte and try the possibilities in order from start to end (and obviously whilst looking for data that doesn't look like garbage). It took me 2 attempts (after attempting start and end bytes first).

A suggestion to find the target section would be look at the hex and think binary (which is made up of a combination of 2 different bits 0's and 1's) and how it could be represented in the targeted area.
