.Bat Key logger

mysafeaccount · Oct 2, 2012

Okay according to my friend he has put a key logger on my machine, by me opening one of his .bat files, is it possible for some one to make a key logger in a batch file, or has he binded it to the .bat file, if so how do I find the key logger, I have ran 4 different anti viruses, Command, malware anit malware, spyware terminator and absolute key logger remover. My machine has come up clean from Key loggers I have scanned the file many times and it has come up clean, but for some reason I really do think its a Key logger, he has wrote it on a Mac, is their any way I can tell if its a key logger or not, if he has a hidden a key logger inside my machine some where and it is so well hidden noting can pick it up, when I right click the .bat file and click edit this is the script in note pad

( Mac OS X 2 R ) some keys did not come out for some reason, he said it was simply a computer shunting down command after cos I got pissed off and it did shut my computer down can some one please help me, I had to make a alternative account and email so he doesn't get my pass in case.
Thank you.

You've been had. You can make a .bat into a keylogger, But the only thing it would be able to 'log' would be anything in the cmd window. Besides, It would instantly be detected (9x). So no, You do not have a keylogger. And for future reference Don't open bat files when you don't write them yourself. 3-4 Lines and a bat can choke a computer to it's limit and have it shut down every time. A key logger in a batch file would be over a 100 lines, C would be about 12. I don't even know how you could fall for such a rouse.

In just one line a batch (bat) file can reformat your C drive. Haven't tried it myself in quite awhile but unless command line permissions prevent it, by the time you figure out what's going on, you're system would have to be reloaded.

You can indeed make a .bat keylogger in a round about way. Basically you get someone to run the .bat at which point you have it decrypt the payload or download a component from the web. In fact, one could even encrypt an exe put it inside of .bat code and then have it reassemble itself. It's actually not very hard at all.

@OP: If you want me to take a look at the source code PM me and you can send me the source to examine via email.

... In the mean time download Key Scrambler from QFX Software (Google it)

Aren't these permissions set by default?

According to your friend???? So a friend did this to you? This person would no longer be a friend.

bat file can use to anything including restart ,shutdown, execute a exe or script. It can use to do more damage to your PC. So be careful when your're try to run .bat file. you can view it on notepad and find the location of keylogger and delete it. Or paste it here and we'll tell you where it is.
I'm also using bat file to change my IP

. So it can use to both good and bad thing..

I posted this in your second thread already:

Did he actually have access to your computer or did you just open a batch file?

The problem is, anti virus does only find malware which is already known.

So,dont trust antivirus software if you know he has the ability to either code his own keylogger OR you think he rly wants to spy on you and purchased a sort of 'private' keylogger.

Furthermore, you can bind two files to one. So no matter what filetypes you open, there might be a chance that someone bound a keylogger to it.

Formatting your C drive with one bat file? Not rly. at least not the script itself. The bat file could only execute some other malware.

Wont destroy your main partition but it would wipe out most windows files. You can completely format all other partitions other then primary with a batch file. In fact, It's only 1 line

You won't be able to format the system partition if the System e.g Windows is running.

If the bat file formats any other partition, its just an annoying time waste to restore the files.
