The various wire services and various astute ISC readers have pointed out the news of the attacks against the DNS root servers.  We are aware of the attacks, and have been waiting to wade through the FUD before publishing anything more concrete.  I am posting this now just to let our readers know that we are aware of the story and that we are trying to get more information about it.  If you have any more information (logs, packets, or if you actually run one of the tld roots) please drop us a line.

The main story is featured here:

There are some graphs showing the traffic rates to the root servers here:

more code injection sites 8.js

We have discovered more defacements / code-injection similar to the superbowl site defacement.
If you google for script 8.js you will find that 1.js and 3 .js were not the only java script’s used in this fashion. This version appears to have been targeted a bit at gaming sites although there is a few medical sites including an “anonymous expert HIV/AIDS counseling” site with this defacement.

Why am I calling this a defacement?
Because that is what we called it in the past when a bad guy gained access to portions of a website and replaced or added their own content to the website. The concept of a website having additional content or having portions of the content replaced was usually looked at as embarrassing but not a major threat. In my opinion with the recent trend to perform “silent defacements” with malicious code injection, world writable content areas should be treated as a threat.

The only malicious version of 8.js I have seen so far is hosted on

<skript scr=hxxp://www.001yl.c0m/8.js></skript>

The stuff I pulled from is very similar to the 3.js defacement we discussed in the dolphinstadium site write-ups.

8.js uses a hidden iframe to hide its reference to qq.htm
document.write('<iframe src="hxxp://" width="0" height="0" scrolling="no" frameborder="0"></iframe>');

qq.htm uses several hidden iframes to call happy1.htm, happy2.htm, happy3.htm from , h.js from and a counter at

Each happy1.htm (and 2 and 3) had pointers to

h.js injects into a cookie.
3.js uses another hidden iframe to call hxxp://
1.htm uses a VML overflow from to run some shell code.

2.exe is not currently well detected the virus scanning engines at virus total:

Internet Explorer msxml3 concurrency problems: update

The CVE-2007-0099 vulnerability has a potential for remote code execution that could make it much more critical than a plain DoS problem as demonstrated by the publicly known exploit.

In our interactions we have been led to believe that the remote code execution vector is too hard to control to be of any practical use to the hackers. Therefore we updated our overview table to reflect a Less Urgent need to act on it.

Samba-3.0.24 was released yesterday to fix 3 security vulnerabilities.  Anyone running an older version should take a look at the release notes and seriously consider upgrading (there are also patches against 3.0.23d available on the Samba site).
