Krieg der Würmer: Verschlüsselung schleust Schädlinge unerkannt an Viren-Scannern vorbei

Vermeintlich seriöse Zip-Files entpuppen sich als Viren-Schleudern

(PresseBox) (München/Gloucester, )
Der Krieg der Würmer ist in vollem Gange. Täglich geben sich neue Varianten von Bagle, Netsky oder Mydoom die Klinke in die Hand. Der vermeintlich "gute" Netsky neutralisiert Mydoom, Virenschreiber verhöhnen sich wechselseitig. Beunruhigender Nebeneffekt: Aus dem Bestreben, die Konkurrenz zu übertrumpfen, erwachsen neue Möglichkeiten, traditionelle Anti-Viren-Lösungen zu umgehen. Neuester Trick im Krieg der Würmer ist das Verschlüsseln von Viren, die sich zudem in Zip-Files verbergen. Während die meisten Viren-Scanner mittlerweile Zip-Archive entpacken und überprüfen können, bereitet die Verschlüsselung nach wie vor Probleme. Die jüngsten Bagle-Varianten F bis I beispielweise kommen in verschlüsselten Zip-Files, das entsprechende Passwort wird im Nachrichtentext xoegxosnrdte.
