Malware Overview

Trend Micro has received reports about this malware being spammed in the wild.

This Trojan arrives on a system either downloaded from the Internet or dropped by other malware. It may also arrive as an attachment to a spammed email message.

When executed, it waits for active Internet connection and accesses the Web site http://www.eden{BLOCKED}et/flash/menu10.swf to download and execute a malicious file, which is saved as KERNEL32.EXE in the root folder (usually C:\). Trend Micro detects the said file as TSPY_GOLDUN.FM. As a result, the routines of the downloaded spyware may also be exhibited on the affected machine.

It also downloads a non-malicious file from the legitimate Web site http://update.microsoft.com.
