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.

PWS-Banker.dldr!0206BCE1 was recently distributed via hyperlinks in spammed email messages. The email utilized social engineering, capitalizing on public focus on the 4/16/07 shootings at Virginia Polytechnic Institute and State University, to encourage the recipient to download and execute the trojan. The message in the email claimed the link to the Trojan was video of the shootings recorded from a camera phone.
