MessageLabs, führender Anbieter von integrierten Managed Services für die Messaging- und Web-Sicherheit von Unternehmen, hat die Ergebnisse seines Intelligence Reports für Mai 2007 vorgelegt. Der Bericht dokumentiert einen deutlichen Anstieg bei plötzlich auftauchenden Spam-Schüben, die wie Spam-Flutwellen über einzelne Domain-Adressen hereinbrechen. Zudem wurden neue Techniken identifiziert, bei denen die Angreifer Foto-Sharing-Websites für ihre Zwecke missbrauchen. Auch im Hinblick auf Viren- und Phishing-Quoten musste ein Anstieg verzeichnet werden.
Spam-Fluten und Denial-of-Service-Attacken
"Spam-Spikes" bzw. "Spam-Flutwellen" treten auf, wenn einzelne Domains Opfer eines besonders aggressiven Spam-Angriffs werden. So wurde bei einem solchen Angriff z.B. versucht, innerhalb von nur 11 Stunden mehr als 32.947 Tjym-Appvhflizrs rk qhbq nmvdmxx Nwlrbe id tsgxqe.
