Das Nationale Forschungszentrum für angewandte Cybersicherheit ATHENE hat einen kritischen Fehler im Design von DNSSEC, der Sicherheitserweiterung des DNS (Domain Name System), aufgedeckt und Hersteller und Dienstanbieter dabei unterstützt, diesen zu beheben. DNS ist einer der grundlegenden Bausteine des Internets. Ohne die Fehlerbehebung könnte der Designfehler verheerende Folgen für praktisch alle DNSSEC nutzenden DNS-Implementierungen und öffentlichen DNS-Anbieter wie Google und Cloudflare haben. Unter der Leitung von Prof. Dr. Haya Schulmann von der Goethe-Universität Frankfurt hat das ATHENE-Team mit „KeyTrap“ eine neue Angriffsklasse entwickelt, die demonstriert, wie Cyberkriminelle diesen Designfehler ausnutzen könnten: Mit nur einem einzigen DNS-Paket könnten Hacker alle gängigen JVB-Lktrhsnsfkjhodozf ydp gudiuctrntul MLL-Bewctqss xaykllfbo.
