This worm spreads throughout the Internet via carrier email and file-sharing networks. The carrier email does not contain the worm itself, but a script Trojan which downloads the worm from the Internet. The worm is coded to infect executable files.
The worm itself is a PE EXE file of approximately 25KB, packed using UPX. The size of the unpacked file is approximately 65KB.

The worm uses the domain name of the recipient of the infected message as the sender's domain name.

The message itself contains a VBS script. When this script is executed by the user, it exploits a vulnerability in Microsoft Internet Explorer (described in Microsoft Security Bulletins MS03-032 and MS03-040) and downloads the executable worm file over the Internet from a number of infected sites.
Once launched, the worm copies itself and its components to the Windows system directory under the names
directs.exe directs.exeopenand registers directs.exe in the system registry autorun key:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] direct.exe=%System%\direct.exe
The worm searches the system registry for keys installed by other worms (i.e.Netsky)
9XHtProtect Antivirus HtProtect ICQ Net ICQNet My AV Special Firewall Service Tiny AV Zone Labs Client Ex serviceand deletes them.
The worm searches disks for files with the following extensions:
adb asp cfg cgi dbx dhtm eml htm jsp mbx mdx mht mmf msg nch ods oft php pl sht shtm stm tbb txt uin wab wsh xls xmland then sends messages to all mail addresses found in these files. The worm uses its own SMTP server to send messages.
The worm searches disks for folders which contain the word 'shar' and copies itself several times to all folders found, under the following names:
ACDSee 9.exe Adobe Photoshop 9 full.exe Ahead Nero 7.exe Matrix 3 Revolution English Subtitles.exe Microsoft Office 2003 Crack, Working!.exe Microsoft Office XP working Crack, Keygen.exe Microsoft Windows XP, WinXP Crack, working Keygen.exe Opera 8 New!.exe Porno Screensaver.scr Porno pics arhive, xxx.exe Porno, sex, oral, anal cool, awesome!!.exe Serials.txt.exe WinAmp 5 Pro Keygen Crack Update.exe WinAmp 6 New!.exe Windown Longhorn Beta Leak.exe Windows Sourcecode update.doc.exe XXX hardcore images.exe
The worm searches all accessible disks for files with the extension .exe. The worm should then infect files by writing its polymorphic code to the end of the file.
The worm opens port 2556 and tracks port activity. The worm's backdoor function enables the remote execution of commands and downloading of files on the victim machine.
The worm attempts to terminate antivirus programs and firewalls by terminating the following processes in memory:

Email-Worms spread via email. The worm sends a copy of itself as an attachment to an email message or a link to its file on a network resource (e.g. a URL to an infected file on a compromised website or a hacker-owned website).
In the first case, the worm code activates when the infected attachment is opened (launched). In the second case, the code is activated when the link to the infected file is opened. In both case, the result is the same: the worm code is activated.
Email-Worms use a range of methods to send infected emails. The most common are:
Email-Worms use a number of different sources to find email addresses to which infected emails will be sent:
Many Email-Worms use more than one of the sources listed above. There are also other sources of email addresses, such as address books associated with web-based email services.
