More Information

W32/Amus-A is a worm for the Windows platform.

In order to run automatically when Windows starts up W32/Amus-A creates the following registry entry:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Microzoft_Ofiz=C:\WINDOWS\KdzEregli.exe.

W32/Amus-A uses the automation interface to Microsoft Outlook. The worm replicates by including the executable as an email attachment. Subjects used by the virus include:

"Listen and Smile"
"Hey. I beg your pardon. You must listen"

W32/Amus-A attempts to use the Microsoft Speech engine to read the following greeting to 'listening' users:

"How are you? I am back. My name is mister hamsi. I am seeing you. Haaaaaaaa. You must come to turkiye. I am cleaning your computer. 5. 4. 3. 2. 1. 0. Gule. Gule."

During playback, the worm may be performing malicous actions based on the current day of the month:

10th, 23rd - worm removes files matching *.ini from the Windows folder.

2nd, 15th, 17th - worm removes files matching *.dll from the Windows folder.

W32/Amus-A may then alter the following registry entries:

HKCU\Software\Microsoft\Masum\
Who = "OnEmLi_DeGiL"

HKLM\SOFTWARE\Microsoft\Internet Explorer\Main\
Start Page = "Konneting du pepil and dizkoneting you. Anlami: Baglansan ne
olacak, baglanmasan ne olacak. Zaten hatlar burada rezalet."
