Einfallstor Word-Dokument: Auch ohne Makros zunehmende Gefahr

Aktueller Internet Security Report konstatiert deutlichen Zuwachs von Malware im vierten Quartal 2017 - Neues Online-Angebot visualisiert aktuelle Gefahrenlage

(PresseBox) (Hamburg, )
Der gerade veröffentlichte WatchGuard Internet Security Report für das vierte Quartal 2017 zeigt ein ernüchterndes Bild: Nicht nur gab es im Vergleich zum vorherigen Quartal eine 33-prozentige Zunahme bei den Malware-Attacken – die Anzahl spezieller „Zero-Day"-Angriffe stieg sogar um 167 Prozent. Hierbei alarmiert erneut, dass 46 Prozent aller Malware-Angriffe von herkömmlichen, signaturbasierten Antiviren-Lösungen nicht erkannt wurden. Weitere Erkenntnis: Cyberkriminelle setzen zur Ausführung von Schadcode zunehmend auf Word-Dokumente – ganz ohne Makros. Stattdessen wird das Microsoft Dynamic Data Exchange (DDE)-Protokoll in Verbindung mit PowerShell-Befehlen missbraucht. Dem Report liegen die Log-Daten von 40.000 Firebox-Appliances zugrunde, die weltweit bei kleinen und mittleren Unternehmen vfuvv ibtpflgby cydqeisvvv Pybtdjchslvwwq ca Dsagohc cpbd dht akbej QF-Ymkrrndcsllkh obfqknpm.
