Acanze.A is simple email worm of Italian origin written in Visual Basic.
Due to the coding techiques used, the worm will only work properly
under Italian Windows versions.
Upon execution, Acanze.A will create a hidden, system file named 'login.bat' into
%WINDOWS% directory. It will then set a registry key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\msnmsgr = "C:\WINNT\login.bat"
The key allows Windows to start the bat file each time a user logs on.
Under Italian versions of Windows, additional files will be dropped, and the
attributes to both file set to hidden, system.
%WINDOWS%\SYSTEM\HOTPLUG.dll
C:\Programmi\Windows NT\netapi.dll
The worm will then check whether a connection to an Italian site can be
established. If so, it will create e-mail messages containing copy of
its body and send them to recipients in Outlook's Contact list.
