harvests email addresses from the victim machine

the From: address of messages is spoofed

attachment can be a password-protected zip file, with the password included in the message body.

contains a remote access component (notification is sent to hacker)

copies itself to folders that have the phrase shar in the name (such as common peer-to-peer applications; KaZaa, Bearshare, Limewire, etc)

uses various mutex names selected from those W32/Netsky variants have used, in order to prevent those W32/Netsky variants running on infected machines

terminates processes of security programs and other worms

deletes registry entries of security programs and other worms

Mail Propagation

The details are as follows:

From : (address is spoofed)

Subject :

Re:

Body Text:

>foto3 and MP3

>fotogalary and Music

>fotoinfo

>Lovely animals

Key - (random number)

Attachment: (with extension .EXE, .SCR, .COM, .CPL or .ZIP)

MP3

Password-protected ZIP files may also contain a second, randomly-named file with one of the following extensions:

.ini

.cfg

.txt

.doc

.vxd

.def

.dll

Installation

The virus copies itself into the Windows System directory as WinXP.exe. For example:

C:\WINNT\SYSTEM32\WinXP.exe

It also creates other files in this directory to perform its functions:

%SysDir% \WinXP.exeopen

%SysDir% \WinXP.exeopenopen

%SysDir% \WinXP.exeopenopenopen

%SysDir% \WinXP.exeopenopenopenopen

The following Registry key is added to hook system startup:

HKEY_CURRENT_USER\Software\Microsoft\Windows\

CurrentVersion\Run "key" = %SysDir% \WinXP.exe

A mutex is created to ensure only one instance of the worm is running at a time. One of the following mutex names is used in an attempt to stop particular variants of W32/Netsky running on the infected machine:

'D'r'o'p'p'e'd'S'k'y'N'e't'

_-oOaxX|-+S+-+k+-+y+-+N+-+e+-+t+-|XxKOo-_

[SkyNet.cz]SystemsMutex
