Stego 1

I'm doing something wrong. I opened it in hex, copyed between the null bytes (didn't copy them), converted them to binary an got exact 2 null bytes at the end. And nothing is missing. But no car is readable. What the ...?

This was a pretty crazy mission! Not sure if this will give too much away, but if you're sitting there puzzling over the where to put this one 'thing' Tiksi forgot, think endianness...

I can't believe I passed it!

First time I started this mission I tried decoding the string and even got further by converting it to a different numeral system twice, but that didn't seem to get me close enough to the answer

Now, after reading the forums and knowing that there was one thing missing, I tried it again. After trying all the possible variations I was about to give up, but was actually so pissed that I started bruteforcing :evil:

To my surprise I got it on the first few attempts, more importantly with a password I thought I had already tried :lol:

Oh, well, good stegano on the whole, thx tiksi! On to the next challange

I don't know what I am doing wrong.

I get the following possible strings after extracting what I though was the stego.

Can someone give me a hint of what I am doing wrong?

You are very close. Take a look at what you have. Some of it's readable, some of it isn't. Maybe a slight change will make it all readable?

OMG, I am sorry for the strings >.<
I will try my best to not put anything that can be consider a spoiler.

Edit: YEAY! I DID IT!
Edit: >.> Damn, I think I have the correct answer. I will post it down in black, and someone tell me if I am lost.
SPOILIER ALERT!
I added a 0 to the first binary block that started with 1 and moved all the bits.
I got this: 8fnhas6 and 00111000 01100110 01101110 01101000 01100001 01110011 00110110.
However, it is not accepting neither the ASCII text or the binary
SPOILER ALERT!
PS: The spoiler must be acceptable in the forums while they are hidden. If someone wants a spoilers Click if you really want it.

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.
