Spybot should add this new threat for detection: Infostealer.Phax




When the Trojan is executed, it creates the following file:
%System%\wnvdsf.ax

Next, the Trojan creates the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VGADown

The Trojan also adds the following winsock service provider:
Name: MSAFD Tcpip [TCP/IP]
GUID: {D69BD79E-10DD-43A0-0028-5F1530000100}

The Trojan downloads the file server.exe from the following location:
hxxp...wxx.club8.tw/serve

The file server.exe then drops the following files:

* avp.exe
* hsvwer2.dll



The file avp.exe is installed as the following service:
VGADown

The file hsvwer2.dll is installed as a Layered Service Provider.

The Trojan may download a configuration file from the following location:
.fh689.com/gunfile/fileo

It may then download the file svch.exe from the following location:
.fh689.com/gunfile/svch

The file svch.exe drops the following files:

* lsass.exe
* md6media.dll



The file md6media.dll is installed as a Layered Service Provider.

The Trojan then targets several Taiwanese online gaming Web sites and games, including the following:

* tw.gamania.com (Taiwanese game Web site, which operates 19 online games)
* gameflier.com (Taiwanese game Web site, which operates 14 online games)
* Rexue Jianghu online

SpySentinel:

Quick question. Was this information gathered independently or are you quoting the signatures of Infostealer.Phax from some other source?

I'd think most antivirus vendors will be covering this one soon.
