Overview

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Characteristics

This threat is detected as VBS/Helvis. When executed, the trojan modifies the registry by setting the following value to 0:

HKEY_CURRENT_USER\Software\MicrosoftWindows Scripting Host\Settings\Timeout,"0"

The trojan then opens up the website www.madblast.com using Internet Explorer. The picture of an Elvis impersonator is then displayed.

Using Outlook, the trojan emails all messages found in the Inbox and Sent Items to the email address vcheckpr@hotmail.com. Messages found in the Inbox are sent to the above address with the subject line modifed with the string "ibox" and the count number. Example:

Subject: ibox1 Hello.
Messages found in Sent Items are sent to the above address with the subject line modified with the string "sbox" and the count number. Example:
Subject: sbox1 Hello
All messages that contain Halloween Elvis in the subject line are be deleted.

The trojan creates another file VirusChecker.vbs in the hard coded path: c:\winnt\profiles\all users\start menu\programs\startup\. This file also sends messages found in the Inbox and Sent mail folders that have been received or sent the day before with the exception of Monday as it sends messages that are three days old.

Symptoms
