Hi guys...
This sure is gonna raise a few eyebrows.
Further to my shell obfuscation ideas from a previous post this is a derivative with ideas that work.
Firstly the file 'obfuscate_master.sh' is created and the access rights changed to the owner only.
It is called in ths particular case as:-
./obfuscate_master.sh 'source ./bash_verbose-substrings.shell'
Notice that $1 is __calling__ a file that does not exist yet but in this example the string can create some commands.
'echo', 'cat', and 'eval' come to mind quickly. Also note that the string is inside single quotes.
Next, the file now runs with the required data as $1 inside single quotes.
Next, two new files are created with access rights to the owner only. In my case, 'obfuscate.sh' and 'bash_verbose-substrings.sh'.
Next, the master file 'obfuscate_master.sh' is deleted as it is no longer required.
Finally, the script continues to the end although the file has now been deleted.
In ths DEMO both new files are saved into the current drawer.
From now on the file is called obfuscate.sh and in this particular case called as:-
./obfuscate.sh 'source ./bash_verbose-substrings.shell'
It goes without saying that once you have your initial variables that you can duplicate or more any or all of the characters needed on the fly.
Also you can overwrite the exisiting variables and re-arrange them in differing orders on the fly.
Also you could allocate variables to every character inside $1, something like 'xyz=${1:8:1}' for the 9th character.
This would give several of variables of the same character...
Boy oh boy what fun... ;oD
For example $1 has a whitespace in it and it is placed into sections of the obfuscated file.
Below is verbose version of the obfuscated code part.
Ensure these files don't exist before running for the first time inside your test drawer of preference...
obfuscate_master.sh
obfuscate.sh
Place this file into your drawer of choice, allocate your access rights and run as previously described...
bash_verbose-substrings.shell
Now the master code:-
The obfuscated code:-
And your private code that you can put anywhere you like so long as you point to it in $1:-
Results for the master file and the final pair:-
Apart from knowing already with the way I have allocated the variables just try and decode the obfuscated code without knowing how it is run.
Enjoy fellas an fella-esses...
EDIT:
(Apologies, as this has only been tested on my OSX 10.7.5, default bash terminal, I put it in the Apple section.)
If you run 'obfuscate.sh' on ots own without its relevant $1 nothing will happen.
The shell in its wisdom will temporarily regard all of the variables as empty and the script just appears as newlines.
And adding to the obfuscation IFS has tab, newline and space characters that you can obfuscate and use too.
Is there ANY other language that can do this?
