Fake Flash Player Zbot spread by "Your Domain"

The malware just keeps flowing! Today the top email-based threats continue to be related to the Zeus botnet or Zbot. The first we've written about previously in our article on November 18th, Zeus: Same Criminal, New Spam which discussed the malware which pretended to be "payment request from (insert company)" and contained a "module.zip" attachment. That campaign fell away finally about 4:15 Friday morning.

To replace it, we have the new version of the "Avalanche" spam. We've received 51,400 copies of this spam email so far. (Yes! The UAB Spam Data Mine is now growing by more than 1 million messages per day - more about that in the near future.) The new campaign lit up about 9:15 AM on Friday morning, and has been unstoppable since.

The email seems especially scary to recipients because it includes your own email address in the subject, and your own domain name as part of the URL to be visited. So, for instance, if your email address were "bugs@bunny.com", your subject lines would be:

dear owner of the bugs@bunny.com
for bugs@bunny.com owner
for bunny.com email service user
please update your bugs@bunny.com mailbox

And your email would read:

Dear owner of the bugs@bunny.com mailbox,
You have to change the security mode of your account, from standart to secure. Please change the security mode by using the link below:

http://accounts.bunny.com.dlsports.be/webmail/settings/noflash.php?mode=standart&id=5236183961831736912306248671355740858547&email=bugs@bunny.com

Even some security researchers thought that others were receiving spam using their company name as the site distributing the virus, but in reality each recipient of the spam email sees his own domain name as part of the website address to be visited.

For simplicity, we'll use "mydomain.com" when we document the websites below.

The webpage looks like this:



After warning that "You don't have the latest version of Macromedia Flash Player", the website offers the fairly standard "Get Adobe Flash Player" icon. In this case, however, instead of fetching from Adobe, it installs from the server you are visiting, from the path "/webmail/settings/flashinstaller.exe".

We've seen twenty-two different domains registered for this round of cybercrime. All of these sites are currently live:

accounts.mydomain.com.ftpddrs.be
accounts.mydomain.com.dlsports.be
accounts.mydomain.com.modertps.be
accounts.mydomain.com.dirddrf.be
accounts.mydomain.com.verzzi.co.uk
accounts.mydomain.com.verzzm.co.uk
accounts.mydomain.com.verzzn.me.uk
accounts.mydomain.com.verzzg.org.uk
accounts.mydomain.com.verzzm.org.uk
accounts.mydomain.com.verzzg.co.uk
accounts.mydomain.com.verzzq.me.uk
accounts.mydomain.com.verzzi.me.uk
accounts.mydomain.com.verzzn.co.uk
accounts.mydomain.com.verzzq.co.uk
accounts.mydomain.com.verzzn.org.uk
accounts.mydomain.com.verzzi.org.uk
accounts.mydomain.com.verzzg.me.uk
accounts.mydomain.com.verzzm.me.uk
accounts.mydomain.com.verzzq.org.uk

The VirusTotal report for flashinstaller.exe shows fairly decent detection with many brands calling this a "Zbot" variant.

The file we scanned was the currently live file:
File size: 123392 bytes
MD5 : f890afa3b55a64b70d45f1b1fc60a77b

Some folks have been confused by the great news from the Metropolitan Police of London this past week. Metropolitan Police's Central e-Crime Unit (PCeU) arrested a pair of twenty-year olds, one man and one woman, on November 3rd for their use of the Zeus bot. You can read more about that arrest in Jeremy Kirk's PC World article or in this Press Release on the Metro Police website.

While its terribly exciting news, and we congratulate all the fine folks at PCeU, they've only arrested one of the many groups distributing Zeus, and not "the big one". While Zeus or Zbot is best known as a stealer of banking credentials, its important to remember that ALL userids and passwords entered on a Zeus victim computer end up in the databases of criminals. Whether these be your email password, your Netflix password, your BestBuy or Dell or Amazon.com or eBay or Paypal, or any other password, it now belongs to the criminals, along with your Credit Card and Banking information.
