This is what it is/was

7/6/2009 11:24:42 AM SYSTEM 312 Sign of "JS:Pdfka-JV [Expl]" has been found in "http://microsotf.cn/img/pfqd.php" file.

It is an infected PDF file. I use Firefox with Nitro PDF tool. The minute Avast flagged this Nitor opened and asked what to do with this file.

Yes, it looks like a line of code got injected to our web page from somewhere external on the Internet (via a vulnerability in the system that has since been fixed), that was wanting to download a PDF file. (reportedly PDF files can be malicious if you have an older version of your PDF reader)

Apparently these things hunt the internet looking for specific vulnerabilities.

This has been removed fron the web page, and things should be back to normal now.

From a google search, if the PDF was downloaded, and managed to infect, it most likely would be delivering unwanted popup ads and possibly other things. You should do a adware/virus scan to make sure things are OK.

There are many good spyware/virus programs, including free scanners (e.g. http://www.kaspersky.com/virusscanner)
I apologize for this inconvenience.


Have Fun!

Peter,
It bothers me that you have to apologize for the inconvenience, since you are doing nothing more than running your business. The people who write these things should be found, prosecuted, and then punished for the harm they cause.

While this may have not been anything other than an infected .pdf file, it may have caused loss of business, loss of time for customers, loss of revenue for customers, loss of time for your employees and such.

In a sense, these individuals are no better than the terrorists and pirates populating our world today. And, at some point, they are going to become just as deadly.

Thanks for getting it cleared up, Peter.

Gary


I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!

the millions or possibly billions of dollars in lost man-hours alone probably far exceeds all other forms of 'piracy' already. to bad someone couldn't come up with a plan to root these people out then prosecute them to the fullest extent of the law. microsoft puts a bounty on their heads but i don't know how affective that has been. maybe a portion of software sales should go into a fund dedicated to exposing these 'terrorists.' the money and effort we all spend on av software would be a good start toward the fund.

just 2 cents from a victim of a trojan that put me out of business with band in a box.

Bob,

The file that popped up when I viewed the PG home page was actually named 955.pdf. Instead of viewing it, I downloaded the file. When I opened it in the Open Office reader, it was blank. However, viewing the file in a hex editor listed more details. Probably like Peter said, it is a specially crafted pdf designed to take advantage of a Window's vulnerability.

According to Adobe:

Platform: Windows XP or Windows 2003 (Vista users are not affected) with Internet Explorer 7 installed

Affected software versions: Adobe Reader 8.1 and earlier, Adobe Reader 7.0.9 and earlier
Adobe Acrobat Professional, 3D and Standard 8.1 and earlier versions, Adobe Acrobat Professional, Standard, 3D and Elements 7.0.9 and earlier

Anyone with the above are in danger of the pdf file using the mail to capacity in adobe to forward information to a 3rd party. I recall using this feature when designing test papers for the fire department, on completion of the test the answers and the users name, date, and badge number were emailed to the Training Office. I'm a little muddy as to how this works in the instance of the webpage, unless it's loading itself as a TSR type piece of software and sending information from forms to another site.

I will not use IE7, and only use that browser if forced to by Microsoft.

Strange, I thought I intentionally used the Firefox browser when I went there..

Using the form feature and mailto feature make sense to me. Anytime you fill out a form, it gets mailed to some guy in China; (think username, password type forms boxes)
Some would call that a keylogger, I certainly would, it is a selective keylogger that only mails out keystrokes entered in forms (probably secure forms). Sounds just about like Spybot decribed it. They claim it is logging any form information and sending it to a remote system. Now if they know the system it is getting sent to... seems like it would be an easy shot for the right 'forensic inspector'.
Yeah, I know, they can hijack innocent computers and use those as stoops.. but it would be a start.

I have links right to the forum, don't go to the homepage. So do you assume that if you go to order something on-line from PG's store that the info ended up going out to Tim-buck-two?

I don't assume anything
I believe PGMusic would have by design any orders going through a seperate secure server.
A secure server will be much harder to infiltrate than a basic webpage server.. although accidental infection is surely possible from admin access.
Since the forum seemed to stay safe during the issue, I believe they have the different components on seperate servers or server partitions. I don't know of any trojan that can jump partitions or domains on a server. Otherwise I would be battling about 15 infected sites right now. One of the infected sites I listed above is still infected after two months (recurring issue) and is on a server that also contains a website I administor. This is how I knew about it to begin with; the guy called us to make sure we knew about his issue and to make sure it hadn't affected our sites, since all sites he administered on that server were getting infected.
I told him it was a sign that he was the one with crap on his shoes and everytime he went in to check his sites he was smearing a little around.
We know exactly what to look for and have seen no sign on our sites.
