pass = n38f298hsjfLevel 4
gif openen, shit op t einde is binnairy en ff omzetten
pass = p68cq1hb
de hash aan t eind van t bestand decrypten ( BASE64 )
pass = hgbvZw07
The original string of 0′s and 1′s from the image between “00 00″:
#stick in a 1
00111000001100110011011101101000011000010111001100110110Is the correct binary stream, which is 837has6
The password is hidden in an audio file. You will need something like WaveLab to complete this misson. The mission is a TFR (Time–frequency representation) audio file.
Get WaveLab HERE.
This is what you will see….
This one is very simple. All you need do is copy the grey picture to your computer. Then load up Paint (yes crappy Paint) and the and then fill the grey picture with yellow and you will get this:
Now just enter the characters into Stego 3’s Window and click ‘check’.
First copy and save the image, there is a binary stream at the end. So if you open the stego4.gif file into a hex editor you will see the binary stream at the end. You will need to convert this into text to complete this mission. (What! You want me to do all the work for you? ) Get on with it! lol
First dump the file into a hex dump file, hd:
hd stego5.bmp | cut -f 2-20 -d ” ” | tr “\n” ” ” | sed ‘s/ / /g’ | sed ‘s/ / /g’ > hd
edit the file and take the 00003a2e off at the end…
There are streams of pixels, with 3 hex bytes representing the RBG. Sometimes they are a little off:
3e 3f 3f 4e 4f 4f 42 43 42 3b 3b 0a
0 1 1 0 1 1 0 1 0 1 1 0
The full bit stream reveals the password to be: syn-ack-rst
This image has a hash stuck to the end of the file.
You can read it like this:
$ strings stego6.png | tail -n 1
That is a base64 encoded string. You can use This site to decode it, or do your own decode. The resulting decode is: (Not like it’s hard to ‘decrypt’) The password is hgbvZw07.
This can only be done in photoshop so as it is expensive I have done it here for you!
What you have to do is load it into PhotoShop and then remove layer 1 – This will reveal.
That’s it: 4aH5CEta
This is just Decimal to Hex to Character. Simple!
This translates to
112 97 115 115 119 111 114 100 61 89 114 82 111 116 55
70 61 73 73 77 6f 72 64 3d 59 72 52 6f 74 37
And finally into this
p a s s w o r d = Y r R o t 7
So the password is: YrRot7
This challenge Stego 9, has a stereo audio file with the left and right out of phase. Mixing them together and merge the sterio wav into a mono wav and you get the morse: This produces the difference, which contains the morse code. Now you can do it yourself by ear or use something like RSCW to work the Morse code out for you.
Well as always I am a lazy person so I used RSCW on Linux, the other OS I have on this machine. So I used RSCW on that.It’s nearly as old as I am. I don’t know if there are any Windows based programs that will do the morse recognition for you but I am sure there is.
The name “RSCW”
The letters RS in the name RSCW stand either for “receive” and “soundcard”, or for “radio sputnik”. The latter is a reference to the original goal for which RSCW was written: decoding the telemetry from the RS-12 amateur radio satellite.
I went on the net and found this like to a small program called MRP40 so here is the link for it HERE I’ve zipped all the programs up for you to save you time in looking for them. But you will need the USERNAME and PASSWORD to access this so you will need to email me HERE:E-MAIL to get the username and password. OK?
Anyway you will still need the Morse Code list to decode the sounds you hear. So here it is:
Morse Code Table
A .- N -. 1 .—- . .-.-.-
And if you listen carefully this is what you will hear: .—- —– –… ….. -…. .—- ..— —– ….- —.. .—- .—- —-. ….. …– —-. —.. —-. —.. .—- .—- –… .—- .—- …–
which equals: 1075612048119539898117113
which is: 107 56 120 48 119 53 98 98 117 113 Which is decimal so look at your ascii table for that.
and that translates to: k 8 x 0 w 5 b b u q
So the Password after all that is: k8x0w5bbuq
Phew! Have a good one from Idletester!
Bacon is a cut of meat taken from the sides, belly, or back of a pig, then cured, smoked, or both. Meat from other animals, such as beef, lamb, chicken, goat, or turkey, may also be cut, cured, or otherwise prepared to resemble bacon. Bacon may be eaten fried, baked, or grilled, or used as a minor ingredient to flavour dishes. The word is derived from the Old High German bacho, meaning “back”, “ham”, or “bacon”.
The first one I think looks like BAABB = T.

This given bitmap has a single row of grey values, with the hint ‘I am the not of a file’. This sounds like the values are the “not” as in, inverse of a file. This python script I wrote will spit out the values of the bitmap:
$ python decode.py > file
So the password is: 6ae4nt5TB
This image has a block of hex:
I thought what I’d do was, I’d pretend I was one of those deaf-mutes I thought what I’d do was, I’d pretend I was one of those deaf-mutes
Scattered 26 times within the file. Simply search and remove all of that from the file – Highlight and delete it -, then open the bitmap in an image viewer to see the correct image.
This mission is real stupid. Firstly you start with the file, then untar it using winzip or whatever: stego14.tar.gz this gives you 6578747261637400.jpg
If you look really carefully at that “jpg” under a hex editor you may notice that is is also a rar file: 6578747261637400.jpg file.rar
Unrar file.rar Extracting key.jpg *5+10 OK!
So you have 2 things now, the cypher text of PGNNZCFYXD (yes that is a “D” at the end, not a “O”) and a key of (*5+10). If you are clairvoyant you might notice that this is an affine cipher. Input this in a decoder: Link here
After you de-cypher all that you will end up with the password. Another silly word!
Put that word into the window and click ‘check
