Hide secret data in any file
#1
This is one of my old UB tutorials, I'll add some images later this day.
I will be explaining a very basic tutorial about how you can store data in any file without writing it directly into the file.

What will you need:
- a Windows computer
- Net tools (Click here to go to the downloadpage)
- a brain

Step 1: Download and install Net Tools 5.
Step 2: Pick your random file (mine is a .txt file to prove that it is not written directly to the file)
Step 3: Open up the program and go to "Start --> File Tools --> Hide Secret Data In Any File"
Step 4: Select the file you want to hide data in.
Step 5: Fill in the Data Name (the variable) and the Data Value (the text you want to hide).
Step 6: Press the "Store data" button.

To retrieve the data back from the file:
Step 1: Select the file you stored data in.
Step 2: Press the button "Retrieve data" and type in the variable's name in.
Step 3: The result will pop-up in a messagebox.

I've always liked this point in tutorials lol.

You know what, I'm liking this post - he who dares prevent me may forth his attempts.

I haven't tried this but isn't it just basic steganography? It will still write to the file just not visible to the casual viewer.

It supposedly uses alternate NTFS streams to hide data, which means it doesn't make any changes to the target file.

Edit :

It's not as basic as direct stego, but still pretty easy to reverse.

1. Download Streams (https://technet.microsoft.com/en-us/sysi...97440.aspx)
2. Scan for alternate streams in a file / dump the stream name :

Code:
streams.exe file.txt

Dump format : :STREAM_NAME:$DATA X

3. Extract data from the stream :

Code:
more < file.txt:STREAM_NAME
