.rm.exe
.htm.exe
.dat.exe
.mp3.exe
.gif.exe
.jpg.exe
.doc.exe
.avi.exe

It changes the following registry entries:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Serv ices\lanmanserver\Shares "GAME" = C:\WINNT\TEMP

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows "run" = RAVMOND.exe

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Cu rrentVersion\Run "Program In Windows" = C:\WINNT\System32\IEXPLORE.EXE

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Cu rrentVersion\Run "Remote Procedure Call Locator" = RUNDLL32.EXE reg678.dll ondll_reg

Under Windows NT/2000, the worm is installed as the following two services:
"Microsoft NetWork FireWall Services" (set to run the copy of the worm with the filename NETSERVICES.EXE) - this service was not installed in testing.
"Windows Management Instrumentation Driver Extension" (set to run the copy of the worm with the filename WINDRIVER.EXE)

Other services are inserted for the backdoor component. Their names are:
ll_reg (set to run TASK688.dll)
NetMeeting Remote Desktop (RPC) Sharing (set to run TASK688.dll).

The worm infects PE files, in which it inserts an infected sector
(DTWTSN16.EXE)and a worm copy. So, in the end, the file has three parts:
INFECTED SECTOR | ORIGINAL PE | WORM COPY.
The infected files are up to 176,648 Bytes.

The worm also tries to access shared systems, using the following passwords:
