backdoor in batch...

Post by hiper »

I was think about to make a backdoor in batch and make it so simpel as possible,
whit this options
1: disable windows firewall (got this part done)
2: revers shell whit cryptcat (got the program but dont know howto add it >.<)
3.make it to copie it self to diffrent locations (working on this part atm =))
4: I think i will add a keylogger, but keyloggers are so LAME tbh >.< (don't have a clue howto write this part)

Is it possible?

Btw iam doing this just to learn more about batch programing and Howto use Cryptcat in a fun way =)

Batch isn't a programming language.

And for this "backdoor" to successfully infect a user, means it relies on other programs to do its bidding for it, which isn't a backdoor at all. A backdoor is self-independent and normally doesn't rely on other processes to complete its task for it. To top that off, to infect your victim, the victim needs to have all the proper tools already installed or placed along with the batch file. So: evilbatch.bat, keylogger.exe, cryptcat.exe must all be in the same folder or directory when the user downloads it, which is quiet suspicious .

A good place to learn how to code keyloggers, I would refer to Maboroshi's post with written source code of his own keylogger. I would also recommend learning a programming language. :wink:

C++ imo is the best, but their are tons of great languages out their you can start with.

Batch is for lazy people who can't write a few arguments in the commandline.

Bash is different from batch, bash considerably has aspects of programming batch doesn't have.

C# is a horrible language and requires the .NET framework, I would avoid anything that deals with .NET.

If you are sufficient in perl, than code the backdoor in Perl. Perl has great modules for networking and some pretty useful web browser modules in which you can toss a reverse shell and attach its process to a web browser making it undetectable. :twisted:
