Virus Alert: New ZBot variant in the wild

by Josh Wilmoth on October 14, 2009

Earlier today we started receiving a flood of emails and phone calls regarding a new trojan ZBot virus variant making the rounds via email.  We have already seen several variants to this trojan in a relatively short time period.  These emails can come from support@*****.com, info@*****.com or alert@*****.com where ***** is the domain name that is being used in the recipient’s email address.  This makes the receiver think it is from a legitimate person or department within your company.

We are recommending identifying the email by the information below then immediately deleting it. Below are some additional identifiers to help keep you safe and secure.

Possible subjects are:

A new settings file for the user@****.com mailbox
The settings for the user@****.com mailbox

Possible email bodies are:

Dear user of the b****.com mailing service!

We are informing you that because of the security upgrade of the mailing service your mailbox (user@b****.com) settings were changed. In order to apply the new set of settings click on the following link:

hxxp://b****.com/owa/service_directory/settings.php?email=user@b****.com=b****.com=user

Best regards, b****.com Technical Support.


Dear user of the ****.com mailing service!

We are informing you that because of the security upgrade of the mailing service your mailbox user@****.com settings were changed. In order to apply the new set of settings open zip attached file.

Best regards, ****.com Technical Support.

The malware is not attached to the email so detection by antivirus applications is difficult.  The email does contain a link that will take you to a website where you will need to download a executable file and apply the new settings.

The ZBot trojan can disable your firewall, steal sensitive financial data (credit card numbers, online banking login details), makes screenshots, downloads additional components, and provides a hacker with remote access to your compromised system.

Some of the symptoms of a possible infection include programs that claim to scan for malware and display fake warnings of malicious files.  They then inform you that they you need to pay money to register the software in order to remove these non-existent threats as well as install new shortcuts on your desktop for “XP AntiSpyware 2009″, “AntiSpywareXP 2009″, “PC Security 2009″ or similar names.  Once these ZBot variants have been installed on your computer you may see fake file scanners, warning messages and fake pop-up warning messages in your system tray.

Here are our recommended security tips to better protect your system:

  • Enable a firewall on your computer
  • Get the latest computer updates
  • Run up-to-date virus and spyware applications
  • Use caution when working with attachments
  • Use caution when clicking on links to websites
