JS:Redirector-CV [Trj] on my website?
« on: May 15, 2011, 03:56:19 PM »
Hi there everyone, yesterday I got stuck with this one; AvastFree started warning me about my site with that Trojan popup.
I made a reverse DNS lookup and other sites of my webhosting provider also had that so I think it's something in the hosting. But, is it real or just a false positive? I scanned my url ( XXX.fuajedrez.com )  with the sites some guys mentioned before, so here are the results and I look forward to hearing from you about this issue I'm having:

Hi leosc, welcome to the forum :)

I get a 404 error on that js file.

Take a look at the file, and check that there is not any extra script added (generally they are added to the end, not definite though)

Thank you Scott.
I don't get the warning only for this file; take a look on the report of the Web Shield, seems like every file is infected, when I know those weren't (at least on my computer, before uploading them):

Just while looking at what is creating the alert, but can I ask what is supposed to be on the site? (i.e what is on the homepage?)

So all those Keygen links are supposed to be there? Thought so... ::)

Seems the initial script is causing the alert...not exactly sure why...

No, they are not! Where is that code at? How do I clean the site?  :)

edit: Is it possible that all the sites of my hosting provider, were "injected" with this ?

That is the contents of the whole page...

Scripts and LOADS of links for torrents/keygens and the like...

I made a search on the index.html but I can't find those codes and links you are showing me.
Where did you find them? Can I clean it somehow? Do you have a clue of how this could happen? Thank you.

It is the contents of wXw.fuajedrez.com/

I see now what you meant about the index page, I imagine that this page wasn't supposed to even exist?

The index.html should exist, and existed, but not with the keygens and all that stuff

wXw.fuajedrez.com/index.html exists and it appears clean, but wXw.fuajedrez.com/ shows the junk.

It is the other items that are on the page that have been compromised, I got 10 alerts (image1) basically on the stuff in the image on Reply #2.

They all have identical content, two very long (rows) strings of obfuscated script (image2) and loading various dubious keygen and software sales sites, etc. etc.

I have broken down the two lines to make it easier to see what that content is, image3.

So it looks very like the site has been hacked.

Where did you get all those *.tmp files? I don't understand how to proceed to clean the stuff.. I downloaded the infected images and css avast reported but when I open for eg. the css i dont find anything wrong inside, I also opened the *.js files and nothing's wrong with them (I just downloaded the original ones, to replace the bad ones, but I get the same story) .. Do I miss something? Thx

Avast creates these temp files of the content coming down on the http stream so it can scan them in its localhost proxy (it doesn't use the original file names) if they are clean then they would be passed on to the browser cache and displayed on the browser page. I just harvest them to be able to look inside.

They are essentially what you showed in your image, just renamed in the avast localhost proxy.

I don't know if you use any form of content management software as that if out of date could be vulnerable to exploit, injecting the code into pages/files.
