Anti Rootkit Blog

Another domain is being used to host the latest version of the Storm Worm. Millions of emails were spammed out from unsuspecting PC users enticing users to download the malware and rootkit.

If a user clicks on the link they will be shown a page like this,

If they click on the link a file called happynewyear2008.exe will be downloaded.

At this moment in time only 9 out of 32 scanners used by Virustotal can detect the current file as malware.

Here is the whois details for familypostcards2008.com with a hint of humor - registered by Larry Claus…

Whats the first thing people all over the world do when they want to find out about something…they Google it!!! “Googling” something has become a keyword in so many people’s lives these days. Googling has an entry on popular online dictionaries http://dictionary.reference.com/browse/google which means it wont be long before you can actually use the word Googling “legally”.

So when millions of people recently got an email with a link to newyearcards2008.com where they could pick up their New Years E Card Greeting they went to Google and did a search for newyearcards2008.com and they would have seen newyearcards2008.com at the very top,

From Google….

“Happy New Year!

Most Google users would think it is legitimate such is the trust in Google these days. When clicked on the user would have seen a page delivered via someones PC whether it be in their front room, bedroom, office, factory floor even unsuspecting Internet Cafe’s all over the world.

Snapshot from newyearcards2008.com

These infected PC users do not suspect a thing because their Anti Virus program shows that everything is ok, all is well. Why? The latest Storm Worm is using a rootkit … http://www.antirootkit.com/blog/2007/12/27/happy-new-rootkit/ . Nothing shows because of the stealth capabilities of the rootkit. It hides all traces of itself from normal anti virus and anti spyware scanners. Different scanners are now required for checking for rootkits. Scanners that know exactly how the rootkit operates are required, check out the Antirootkit Software page for list of new scanners.

Why does a search of newyearcards2008.com show the main infection site up first on a Google search? It’s all about how many pages on the internet link to newyearcards2008.com. Even by me putting newyearcards2008.com in this blog will help the name climb the Google ladder so that it shows at the very top and stays top for as long as it can, fooling people into thing it is legitimate ( I mention newyearcards2008.com a lot here so that this blog entry will raise higher than newyearcards2008.com and people will read this warning before getting their New Year’s “Surprise” E-Card).

The people who registered newyearcards2008.com, they went about getting the domain name mentioned on a lot of internet pages around the world, mostly on blog pages belonging to Google. Most of the Blogspot pages have been disabled by Google but many Blogspot and Blogger owners who are using their own domain name have links to newyearcards2008.com in thier “hacked” blogs.

If you suspect a site as being unusual with unusual activity then you can report it to Google and help them mark it as suspect. You can report to Google, suspect sites, via http://www.google.com/safebrowsing/report_badware/

A recent Trend Micro Blog entry highlights Blogger pages being used to harbor links to newyearcards2008.com… http://blog.trendmicro.com/hundreds-of-blogger-pages-harboring-new-years-storm-links/trackback/
So far as of 29th Dec GMT newyearcards2008.com is showing tops, lets see when it is highlighted as a suspect site by Google on a web search.

Also keep an eye out for newyearwithlove.com

The Storm Worm has been doing it’s latest round since 23rd December. It has been masquarding as a christmas strip show enticing users to get infected. Prevx have been tracing the movements of the worm and have seen over 700 variants in a few days.

The worm is proving very elusive because of its fast flux method of evading detection.
“Fast-flux is basically load-balancing with a twist. It’s a round-robin method where infected bot machines (typically home computers) serve as proxies or hosts for malicious Websites. These are constantly rotated, changing their DNS records to prevent their discovery by researchers, ISPs, or law enforcement.”

Then on Christmas day it changed its form to now entice people to click on a New Years Card called happy2008.exe and happynewyear.exe which users would download from legitimate looking sites called happycards2008.com and newyearcards2008.com

as we can see both are using a lot of nameservers which each can be used to point the person who clicks on either HAPPYCARDS2008.COM or NEWYEARCARDS2008.COM to one of millions of computers in a botnet which has the infected happy2008.exe or happynewyear.exe waiting to be downloaded.

As we can see the Domain names were registered in Russia.

Current Variants of the worm have a rootkit element that can be used to hide from many antvirus and antispyware scanners.

“Last versions of Stormy worm are using a rootkit component to hide infection components.

After launched, the dropper create a new service and a driver under Windows System directory called clean[4 random chars]-[4 random chars].sys or bldy[4 random chars]-[4 random chars].sys

Driver will hook three Windows native API: ZwEnumerateKey, ZwEnumerateValueKey, ZwQueryDirectoryFile. Goal is to hide its registry keys and files.

As side effect, it’ll hide every file that contains the strings “clean” or “bldy” in its name.”
From Prevx..

Prevx provide a free scanner called Prevx CSI that can detect these new variants..Download Prevx CSI for free …

Have a Happy New Year… no really…

“The Rise of the Rootkits has begun” are the words of Jacques Erasmus from Prevx who commented recently on the increase in the use of Rootkits.

“Significantly, although rootkits were detected on 15.6 percent of PCs during October 2007, that figure had risen to 22 percent by early December.”

This indeed shows that there has been an enormous increase in the use of Rootkits in one month alone and the trend is very much upward. The Rootkit List shows that since Nov 1st there has been 79 rootkit related stealth malware creations found by leading IT Security Companies. November has been one of the biggest months of the year so far for new found rootkit creations and variations. This could be down to the fact that online criminals are getting their arsenal ready for Christmas when a lot of people will be buying presents online.

The Prevx results have come from information gathered from the Prevx Online Scanner. This online scanner was used mostly by users who suspected something was wrong with their PC. The Rootkit files found by the Prex online scanner include NDT2.SYS , SROSA.SYS, UNPR.SYS, FMTR.SYS, and INDT2.SYS.

It seems also that a lot of businesses are being caught off guard by Rootkits. “In the first nine days of this month alone, 93 companies used the free Business scan feature of Prevx CSI. Of these companies, 68 had one or more infected PCs. Thirteen companies, or 14 percent, had one or more PCs harbouring rootkit infections.”

To check your PC for Rootkits check out the Antirootkit Software Page.
