Wie das ‘Bulletproof”-Kit Secure-EGateways und Multi-Factor-Authentification umgehen kann
Die Sicherheitsforscher des KnowBe4 Threat Labs haben eine aktive Phishing-Infrastruktur untersucht, die gezielt eine Schwachstelle klassischer E-Mail-Sicherheitsmechanismen ausnutzt. Das von den Angreifern selbst als ‘Bulletproof” bezeichnete Redirector-Kit versteckt die eigentliche Phishing-Infrastruktur hinter kompromittierten, legitimen Websites. Dadurch können schädliche Links Secure-E-Mail-Gateways (SEGs) und klassische URL-Reputationsprüfungen umgehen. Das Umgehen von SEGs ist jedoch nur ein sekundärer Vorteil.…
