  Visão geral

Canal de infecção: Aus dem Internet heruntergeladen, Fallen gelassen von anderer Malware, Verbreitet sich per E-Mail

Ändert bestimmte Registrierungseinträge, um Funktionen des Security Centers zu deaktivieren. Dadurch kann diese Malware ihre Routinen unentdeckt ausführen. Umgeht die Windows Firewall. Dadurch kann diese Malware ihre geplante Routine ausführen, ohne von einer installierten Firewall entdeckt zu werden. Erstellt bestimmte Registrierungseinträge, um Sicherheitsanwendungen zu deaktivieren.

Sammelt Empfänger-E-Mail-Adressen aus zwischengespeicherten E-Mails, Adressbüchern und Postfächern.

Ändert Zoneneinstellungen von Internet Explorer. Setzt die Sicherheitseinstellungen von Internet Explorer herab.

Installation

Schleust die folgenden Eigenkopien in das betroffene System ein und führt sie aus:

  • %User Temp%\{random filename}.exe
  • %System%\{random filename}.exe

(Hinweis: %User Temp% ist der Ordner 'Temp' des aktuellen Benutzers, normalerweise C:\Dokumente und Einstellungen\{Benutzername}\Lokale Einstellungen\Temp unter Windows 2000, XP und Server 2003.. %System% ist der Windows Systemordner. Er lautet in der Regel C:\Windows\System unter Windows 98 und ME, C:\WINNT\System32 unter Windows NT und 2000 sowie C:\Windows\System32 unter Windows XP und Server 2003.)

Schleust die folgenden Dateien ein und führt sie aus:

  • %User Temp%\{random}.reg ← used to add registry entires; deleted afterwards

(Hinweis: %User Temp% ist der Ordner 'Temp' des aktuellen Benutzers, normalerweise C:\Dokumente und Einstellungen\{Benutzername}\Lokale Einstellungen\Temp unter Windows 2000, XP und Server 2003.)

Autostart-Technik

Step 7

Diesen geänderten Registrierungswert wiederherstellen

[ Saber mais ]

Wichtig: Eine nicht ordnungsgemäße Bearbeitung der Windows Registrierung kann zu einer dauerhaften Fehlfunktion des Systems führen. Führen Sie diesen Schritt nur durch, wenn Sie mit der Vorgehensweise vertraut sind oder wenn Sie Ihren Systemadministrator um Unterstützung bitten können. Lesen Sie ansonsten zuerst diesen Microsoft Artikel, bevor Sie die Registrierung Ihres Computers ändern.

Step 8

Führen Sie den Neustart im normalen Modus durch, und durchsuchen Sie Ihren Computer mit Ihrem Trend Micro Produkt nach Dateien, die als WORM_CRIBZ.J entdeckt werden. Falls die entdeckten Dateien bereits von Ihrem Trend Micro Produkt gesäubert, gelöscht oder in Quarantäne verschoben wurden, sind keine weiteren Schritte erforderlich. Dateien in Quarantäne können einfach gelöscht werden. Auf dieser Knowledge-Base-Seite finden Sie weitere Informationen.
