More Information

W32/Kipis-J is a mass-mailing and peer-to-peer worm.

When first run the worm opens notepad.exe while it copies itself to the Windows folder as regedit.com and the created %SYSTEM%\1032 folder as svchost.exe.

On Win9x systems the worm modifies the system.ini file adding the following entry to the [boot] heading:

Shell=Explorer.exe C:\Windows\System\1032\svchost.exe

On Windows NT and above systems the following registry entry is changed by the worm from:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell
Explorer.exe

to:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell
Explorer.exe %SYSTEM%\1032\svchost.exe

W32/Kipis-J may also copy itself to folders with the string "share" or "\Microsoft Sh" in their name using all of the following filenames:

Windows 2000(source).c.exe
Kaspersky Antivirus(crack for all version).exe
ICQ Longhorn new! .exe
Ahead nero 9.exe

Worm.Beagle source.doc.exe
Jpeg exploit(source).c.exe
MS Office crack.exe
IE 6.0 exploit(src).exe

The worm will search local drives for files with the following extensions from which it will attempt to harvest email addresses:
