Technical Details

The email composed from the following parts: Subjects:

"Storielle.."
"Divertimento assicurato.."
"Leggete urgentemente questa email!! (se avete tempo da perdere)"

Message body:

"dai un' occhiata all' allegato e ti farai due risate ;-)"
"devi assolutamente vedere il file che ti ho allegato."
"guarda l' allegato... ti potrebbe interessare."

Attachment:

"bar.exe"
"pippo.exe"
"porkis.exe"

When the attachment is open first it installs itself to the Windows directory as "dllmgr.exe". This exe file is added to the registry so Windows will start the worm when the computer starts.The registry value is:

  • 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\Dll manager'

After this it displays seven message boxes with Italian messages and exits. The installed copy at next startup opens the Windows Address Book and mails itself to all the addresses it can find there. Due to a bug in the code the worm can't find the correct addresses in the WAB file so it is unable to spread.On the September 6th it displays the following message:

F-Secure Anti-Virus with the latest updates detects this worm.
