Agent Fox Mulder and Agent Dana Scully Investigating a
Homicide case found some files that don't seem to be
normal on the suspected psycopath's computer. They
Suspect that those files could reveal information about
his next to be victim.
Their Computer Experts analysed those files and found
that the bitmap file should have the image of a man.
Strangely though, they were unable to Identify him from
the distorted image. All they Could come up with, is..
- The Image is Not Encrypted
- No File is hidden within the Image File
Also the Audio file did not help them either. It seems to
be an alien voice saying something. They can confirm
that the file is not encrypted and no file is hidden within
the audio file.
Mulder and Scully heard that you are an expert in this
field and are requesting your help !
Please help them.
-
Well, at least it won't matter -- he's already dead!
-
Too easy.. The wav was too less encrypted ;) Well I can't get the connection to the picture, though.
-
Okay...I've solved the picture puzzle...that was too easy even by my standards :D
-
Got it ;)
But I dont get the bmp thou?
-
Hm, yeah.. its not encrypted and its not renamed (header identifies it as BMP)...
so maybe it just has the wrong size? I have no time to code such a tool now but Id say its something like this.. :rolleyes:
-
I have found the answer.. The picture, is a picture of Mike, it was distorted like that because the camera broke at the exact same second the shutter clicked. The .wav file is a clip of what Mike sounds like when he is drunk... :rolleyes:
-
So there is no real picture hidden?
-
There's definitely a picture there :) I found it in about 10 minutes (using trial and error).
-
So Parksie and Fox get it right...
They However have to explain the other file.
But don't cheat !
ah... I running out of UPS power..
I facing a Power Black out here...
-
It's easy to explain. The file has been altered to set the supposed width to be a larger value than the data exists for. Therefore the lines are all out of alignment, giving that fairly classic pattern. You get it all the time when using RAW files.
-
Well, How do you fix it then? Do you just resize it?
-
I got what the .wav file was saying. But can't figure out the bitmap!
-
Actually .. Not only the width is changed...
The width is swapped with Height...
How about the Audio file ???
-
Ok...Now what you have to do..is send me the
Corrected versions of both the files(Zipped) to..
[email protected]
-
Ok I know what the picture by looking at it and i know what the sound is, but how do I change the pic to normal, and vice versa?
-
Ok...I recieved Parksie's Image...
Parksie gets a tight Hug from Scully ! :D
Parksie will do the Explanation part..
-
In yer BMP file, swap the values (using a hex editor) at offsets 0x12 and 0x16, this is where the width and height are stored :)
For the sound file, load it into sound recorder and speed it up :)
-
I mean.... I received both the corrected files.
That is in a format Understandable by all.
-
Cool. So, how about another challenge Active?
-
Decoding the Sound is the Easiest one..
use soundrecorder ..and increase it speed exactly by 200%
If you don't know where sound recorder is..
put
sndrec32 in the start menu ->> Run Box. and enter
-
Does anybody have a hex editor that I can download? I can't seem to find any :(

Here is hiew...dos program
put a short cut to it in the Windows send to folder
and then right click any file and choose send to hiew..
-
Thanks, but how do I use it?
I have the file open, but I don't know how to replace values... :confused:
-
Sorry.. I forgot to tell you that ! :p
Use the Enter key to cycle through
the Text Mode(The default screen when you open a file)
the Hex edit Mode (where you do the Hex-editing)
the Disassembly mode (Yes...you are seeing it right ;) )
In the Hex Editing mode
Get to the Required offset using the Mouse or the
direction keys and Press F3 to start Editing.
Press F9 once you are Ready to save it..
F10 to quit.
Use Tab keys on the Hexediting Screen to Switch from Hex Pane to Ascii pane.
This is the best Hex editor I ever Found.
