A trojan horse appears to be found in the VDSVdd.DLL

If you have any copies of this file, DELETE AND DESTROY THEM AS
SOON AS YOU CAN.

The file seemed to be modified by tools which are not open
to public, supposedly available to only those in the "inner rings" of
cracking groups. The file contains WinInet and other API calls which
have absoulutely nothing to do with a virtual drive. The file had
something attached (bound) at the end which is most likely a
trojan horse.


It can be inferred that this DLL contains a keylogger and will send
information to a pre-specified place. It could also send key files you
have from your products.

The VDSVdd.DLL was authored by a user most lately known as
"Rinauld Raymond". He is a cracker who has returned repeatedly
to VDSWORLD to cause trouble and has even put trojan horses
in his files to steal keyfiles. He originally came as "H@llowin__Hia",
you can search http://archive.vdsworld.com/search.php for "trojan"
and you'll see some results. Rinauld is certainly not using a real
name, but we are aware of who he is. He has been banned and he
will continue to be banned as he comes back, no questions asked.

The file has been removed from VDSWORLD and is not available for
download here anymore.

FOR THOSE WHO HAVE RAN THIS FILE, WE RECOMMEND THAT YOU

TCPView http://www.sysinternals.com/ntw2k/source/tcpview.shtml is a good free tool that will show you what is communicating over the Internet, and to where.

Jules thanks for that info It will be very useful Smile
BTW I advice against anyone experimenting/risking with this dll to see where it connects.

Hi All,
I don't think this file is a Trojan Horse. If you look at the file with a hex editor you will see that the author or the compiler that the author used has written a string at the end of the file for registration purposes. I scanned this file with Norton Anti-Virus that has the latest dat files and it did not report anything wrong with the file.
Also note that this DLL has what I think is some kind of ActiveX security system as a binary resource. I am not saying that this file is safe but I am saying that so far I have not found anything that really looks bad in the file at the binary level.

I see that also the VDSZIP.DLL has been disabled on the main site, I
assume because it also was from the same author.

I've used both of these dlls and neither have attempted to make any sort
of connection through or to the net. I have not lost any data, had any
crashes, any infections, festering warts, lockups, lockouts, lockins, files
added, files deleted, files mauled, files raped or fondled or anything else.

I have also had no AV warnings at all on either of these dlls.

Either these dlls have found a way around AV's and Firewalls, or you are
mistaken about them being a trojan.

Has anyone recieved a warning from their firewall or from an AV program
regarding either of these dlls??

-Garrett

I asked for those two dll's to be pulled temporarily until we find out if they are indeed valid or contain suspect code.

Better pull the vdslists.dll also, as it also contains the same exact
references to wininet and urlmon as the vdsvdd.dll.

I also noticed that several other dlls seem to have what looks like
something attached to the end of them also. I would have to assume that
these are most likely the registrations routines.

I've only checked a few dlls, but more might contain the references to
wininet.dll and urlmon.

Garrett the difference between vdslists and the other dll's is we all know Tommy and Tommy wouldn't do anything like this. On the other hand while you are listed as the author of the vdszip, it was another person who actually wrote and compiled this dll for you.

We've asked you several times who this person is that wrote the dll for you (and who we suspect is Hallowin - a previous pirate and problematic person here) and you never did give us this persons name.

No one is questioning your character here and no one is suggesting that you are intentionally putting trojans in your files but the person you are dealing with and is building dll's for you (since you won't give us the name, we can only suspect who it is) is someone who cannot be trusted. There's no telling what is put in that code before he compiles and gives it to you.

After being told who this person is you continue to work with him in the hopes of 'helping him change his ways'. I don't think this person will ever change their ways until they grow up, in the process you 'MAY' let me stress 'MAY' be putting out files that are infesting other peoples computers. I really don't think its worth ruining your reputation and
'MAY' be runing peoples property to try to help someone who 'MAY' be deceiving you.

You can easily solve this by having any dll developer here take a look over the code to see if anything malicous is in it and then allow them to compile the dll for you. Of course if you need some agreement or contract that the developer cant use your code for any other reason this I think would be more then appropriate for any developer here willing to help you.

Yeah they could also be just file data reorganised by protector etc etc. But as far as this file is concerned only someone who decompliles the file in question can give a very certain answer becuse the author does not seem to be to be trustworthy as everyone feels.

Hi Doctor
I am not trying to prove or disprove anything but just in case you
don't know tELock has both public and private builds, private being
used by cracking groups.
