Neuer Botnet Nugache macht Signatur-basierte Sicherheitskonzepte uneffektiv

(PresseBox) (München, )
Vor einem neuen Botnet warnen die Sicherheits-Experten von Secure Computing. Das Nugache genannte Bot verwendet Verschlüsselung und Zufallskommunikation um Signatur-basierte Verteidigungsmechanismen auszuhebeln.

Dazu nutzt Nugache Peer-to-Peer Kommunikation ohne Comand Control (C&C). So bleibt die normalerweise erkennbare Kommunikation zwischen den einzelnen Bots und ihrem Command Control Server unerkannt. Gleichzeitig bietet dieses Prinzip ein neues Niveau an Ausfallsicherheit für das Botnet.

Dabei setzt Nugache auf die folgenden Schwachstellen der heute gängigen Abwehrmaßnahmen:
- Mangel an Anti-Malware Scanning.
- Einsatz von herkömmlichen, kategorie-basierten URL Filtern
- Keine granulare Applikationskontrolle.
- Verlass auf Signaturen nach einem negativen Sicherheitsmodell, das bedeutet, es wird jedem Traffic der Durchgang kuxrhsy rcu ewuuyblb cbg ywgvnmqhoa qwvvz Vacobhgwyd cf xdezcrx.
