HINT: This is an encoded message, the only tip you get is '2 null bytes'

solution

Open the picture in a hex editor and search for two null bytes.

converting 16 to binary shows 0 as least significant bit

Binary convertor link here

converting 17 to binary shows 1 as least significant bit

Now replace 16 with 0 and 17 with 1 .As we know that every 8-bit binary digits represent one ASCII character. Therefore, one bit is missing. After some hit and trials, I found that the missing bit is the trailing 0 of the first character. Now, after decoding the binary we get the password.

HINT:

solution

Extract the strings from the picture Check the strings you will find code that looks like it is encoded in Base64

code=Tm90IGxpa2UgaXQncyBoYXJkIHRvICdkZWNyeXB0JyB0aGlzIGh1aD8gVGhlIHBhc3N3b3JkIGlzIGhnYnZadzA3Lg==

Decode this code with Base64 decoder\

Decoded=Not like it's hard to 'decrypt' this huh? The password is hgbvZw07.

Password = hgbvZw07

HINT: kiss me alone

solution

Peform spectrum analysis of the song. You will find long and small dashes in the soundtrack.

Spectrum analyser link here

It is morse code .Taking small dash as a dot(.), large dash as (-), small space as space and large space as (/). On decoding, we get the following Morse code.

".---- ----- --... / ..... -.... / .---- ..--- ----- / ....- ---.. / .---- .---- ----. / ..... ...-- / ----. ---.. / ----. ---.. / .---- .---- --... / .---- .---- ...-- "

Decoding the moorse code we get decimal numbers

morse code decoder link here

107 56 120 48 119 53 98 98 117 113

convert the decimal into ascii you will get password

Stego 10
Look at the picture of the words.
encode it yourself, then decode with version 2.
For every bold letter is a B
and
For every not bold letter is a A

The first one I think looks like BAABB = T.
BAABB = T
AABBB = H
AABAA = E
ABBBB = P
AAAAA = A
BAAAA ……..AND SO ON!

answer = thepasswordisnothere
So just use that and its complete: nothere
Done!

Solution

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:

#!/usr//bin/python
import Image
import sys
im = Image.open(“12.bmp”)
newnumber = 0
oldnumber = 0
counter = 0
width = range(0,123)
hight = range(0,1)
for each2 in hight:
for each1 in width:
it = im.getpixel((each1,each2))
print chr(255-it),
sys.stdout.softspace = 0
print
If you run this you get:

PK???t??8ZJ?Gpass.txt6ae4nt5TBPK????t??8ZJ?G? pass.txtPK???6/
There is something in there… is that a zip file?

$ python decode.py > file
$ file file
file: Zip archive data, at least v2.0 to extract
$ unzip file
Archive: file
extracting: pass.txt
$ cat pass.txt
6ae4nt5TB

So the password is: 6ae4nt5TB
