NBC site redirecting to Exploit kit

We became aware that the NBC[.]com website is redirecting to malicious websites that contains exploitkit.

At this point it seems like most of the pages contains an iframe that is redirecting to the first stage of the RedKit exploit kit.

Some twitter users are already poiting out some of these bad pages.

Some of bad iframes public known are:

hxxp://www.jaylenosgarage[.]com/trucks/PHP/google.php

hxxp://toplineops[.]com/mtnk.html

hxxp://jaylenosgarage[.]com

The Redkit exploit kit will deploy the banking trojan Citadel.

We will update this diary when more info become available.

I'm not sure if these are related, but they showed up in my logs right after a coworker visited nbc[.]com

Yes, they are related. Check those machines closely. The exploit kit will try to push a PDF or Java on most of times.

Yes, and they have multiple issues going on. Some are embedded in javascript files, others are embedded directly in the pages EX: http://www.nbc.com/community/video/paranormal-parentage/n32778/ has the following on line 415:

http://umaiskhan[.]com/ztuj[.]html

And on view-source:http://www.nbc.com/1600-penn/video/at-the-monitors-bruce-campbell-pt-1/n31463/ line 411:

http://nikweinstein[.]com/cl/google[.]php

It's been reported to google and it appears that the malware warnings are starting to display.

Ahem...

I wonder why there is no browser function to enable processing for URL's for the domain you are just visiting only.

Like the cookie rule I mean.
("Accept cookies only from the site I visit")

For example if i open "isc.sans.edu" this browser session only handle URL's with "isc.sans.edu\*".

That would be nice -- if it would eliminate advertisements on the "top-edge" or "right-edge" of web-pages on some sites, because those advertisements usually originate from some other domain.

Oops! That blows-away the "revenue-model" for web-sites that inject advertisements along with the content that I want to see.. :-)
