Brief Description
W32/Downloader.ANCJ is a Trojan that downloads other malicious files and executes them.


Technical Description
W32/Downloader.ANCJ was spammed as an attachment to an e-mail claimed to come from eBay. The attachment is named Ebay.pdf.exe and has the same Icon as pdf files on system that have installed Acrobat reader. This is done to try to trick the user into thinking it is safe to double click on the file.

Upon execution it displays a message prompting the following:

Acrobat 6 - Error "Warning" 20225

Next it tries to download files from a list of hardcoded Internet addresses. These files contain encrypted Internet addresses of other executables which it downloads and executes.

At the time of this writing the files downloaded were executables which try to steal usernames and passwords for such sites as eBay and e-gold.
