– HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   • "unknow"="ai.exe"

– HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
   • "unknow"="ai.exe"

– HKCU\Software\Microsoft\Windows\CurrentVersion\Run
   • "unknow"="ai.exe"

Um die Windows XP Firewall zu umgehen wird folgender Eintrag erstellt:

– HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\
   FirewallPolicy\StandardProfile\AuthorizedApplications\List
   • "%windir%\system32\ai.exe"="%windir%\system32\ai.exe:*:Enabled:@xpsp2res.dll,-22019"

Infektion über das Netzwerk Um die weitere Verbreitung sicherzustellen versucht sich die Malware mit anderen Computern zu verbinden. Die Einzelheiten hierzu sind im Folgenden beschrieben.

Eine Kopie seiner selbst wird in folgenden freigegebenen Netzressourcen erstellt:
   • \profiles$
   • \IPC$
   • \D$
   • \print$
   • \E$
   • \Admin$
   • \c$\windows\system32
   • \c$\winnt\system32
