CMD: Filename or extension is too long

How much are you charging for this script that it would be beneficial for them to steal it. Does Yzowl make a percentage ? For the right price, I will rewrite the entire thing to be encrypted and only decompile in RAM.

CMD batch or converted to a different language?

I'm enthusiast about security, and i want to learn, to learn, to learn, this is the way for me! I'm curious if exists a way to don't decompile in the the HD. I know that is possible to do what you wrote with VBScript, not with a CMD batch.

It's not really a security issue though is it? You are installing updates, you are telling them you are installing updates and you are showing them which updates you are running. The only time the file could be read from the hidden location is during the updating process, whilst it's running, and even then it would only be found by someone specifically knowing what to look for and where to look for it. The file contains nothing which would benefit anyone other than someone wanting to know how to formulate a for loop; what's wrong with them wanting to learn something too?

ExeScript

Executable files produced by ExeScript are securely protected with industry-standard AES encryption, making it virtually impossible to extract the original script files from the executable. ExeScript never saves or extracts the original script files onto the hard disk during the execution. Instead, all information is securely kept in the computer's RAM, which makes it hard or impossible to obtain the source code from EXE files while they are running.

To protect your scripts against unauthorized use, ExeScript can set a password to run, making it impossible to launch a script without knowing the right password. Secure AES encryption and password-protection make converted BAT to exe, VBS to exe files secure for wide distribution.

Because everyone can access to that folder and get the batch.

Wouldn't it be protected by Copyright Laws? :unsure:

In any case you could have people to which you provide the install routine to sign a NDA:

You know, just to be on the safe side. :whistle:

The only thing I can think of is that you are using the same basic batch to not only install updates, but also install something else, and that is what you don't want people to see. If that is true, then that secrecy implies something nefarious, and if I was one of your users I would be that much more curious and would trust you less in general.

I also noted that you did not answer my previous questions. I can understand that you "want to learn, to learn, to learn", but what exactly are you wanting to learn and for what purpose?

Cheers and Regards

Hi bphpt, if you want we can do a game... you ask a question to me and i ask a question to you. Is this a specialist forum or a facebook branch?? :lol:

Hi Yzöwl, that program decompiles the batch into the HD. Anyway, since you know more things than me in this area and i wish to learn, can i send you some PM if i have need? Please let me know.

To learn, to learn, to learn, always! :hello:

The site information suggests otherwise, did you see the section I quoted? specifically the text in red!
can i send you some PM if i have need? Please let me know.
I see no reason to refuse you the opportunity to do so. If I find something in your PM which may be of interest to the Forum and it can be made public without causing privacy/security issues I may after review ask you post it here.

Only the VBScript files can be decompiled without to be extracted. The batch (bat or cmd) files must be extracted in the %TEMP% folder (default) or in a user specified folder.

It will be an honor for me to learn from you and i hope you won't refuse my questions. Thank you. :hello:

Yzöwl i've an idea! Could it to be possible to obfuscate the content of a batch file?

I can create a compiled exe file from an authoring software, a GUI with a button. Clicking on that button, i can launch the CMD batch file with a specified parameter, for example: mybatch.cmd -param

You wrote for me something like this some months ago:

@ECHO OFF
ECHO=_%~1|FINDSTR/X "_-param">NUL 2>&1||GOTO Error

ECHO Logged succesfully
>NUL PAUSE
EXIT

:Error
ECHO Error
>NUL PAUSE
EXIT

My idea is that the batch should recognize the correct parameter given (%~1) and apply it as "algorithm key" to decode the obfuscated batch.

I hope to be explain me fine.

Thank you
