JS:Redirector-H [Trj] at website
« on: April 29, 2009, 06:08:56 PM »
Avast gives me this Trojan warning @ hxxtp://www.gmdny.com which is a viable New York State contract website.
It appears only Avast picks this up...legitimacy please???

I think what Omid meant was that you should modify your first post - make the link there unclickable...  ;)

The site has been hacked, there is a large chunk of obfuscated javascript just before the opening Body tag of that page, see image. I modified the code to make it easier to see in the image as it is on a single line.

avast is all over these injection infections like a rash.

David, do you know a tool to make this script able to read a little easier than what it is now?  ???

avast is all over these injection infections like a rash.

I don't have a definitive script to check it, ther is a site I use on occasion, http://www.felgall.com/javamet6.htm when trying to look at unescape script like that above. However, there are frequent times when even that doesn't reveal the true intent. Alwil software have their own script checking tool so they are able to decode what the intent is (redirection, probably to a malicious site/script).

So suffice to say that javascript is a plain language scripting language, so when people go to these length to hide the purpose that makes me very suspicious.

Thanks David for the link, I appreciate it :)
I know about Alwil and their program to read those kind of script.

Yes this is a fast growing exploit hacking legit sites and injecting either iframe or script tags into the page/s to redirect to a malicious site where the payload resides. The script responsible for the redirect is at the bottom of the page, see image1

There is also another alert on that site as the favicon.ico file has been replaced with an html page purporting to be a 404 error page redirecting also to a malicious site, image2 & 3.

So you should report it to the site owner/webmaster, etc.

Hello, this is my first post here.
I am the owner of a small website with a phpbb forum called hxxt://www.problemefiat.ro . Problem is I've been hit by this  JS:Redirector-H [trj] 3 days ago . So far I tried cleaning the php code...no result. Today I have deleted my files from the hosting and copied a back-up I have made a while back. The site stayed clean for about 16 hours and now is infected again. Does anyone know how to protect your website from these type of atacks? Or do I need to restore my back-up every day ? :(
Thanks!
