Proofpoint, Inc., (NASDAQ: PFPT), eines der führenden Next-Generation Cybersecurity- und Compliance-Unternehmen, hat kürzlich mehrere kritische Sicherheitslücken bei der Implementierung von Multi-Faktor-Authentifizierung (MFA) entdeckt. Diese betreffen Cloud-Umgebungen, bei denen zur Authentifizierung das Protokoll WS-Trust verwendet wird. Mittels dieser Schwachstellen ist es Angreifern möglich, MFA zu umgehen und auf Cloud-Anwendungen zuzugreifen, die das betreffende Protokoll verwenden. Unter Umständen betrifft dies auch Microsoft 365. Im Falle eines erfolgreichen Angriffs könnte ein Hacker vollen Zugang zum Konto des Opfers erhalten (einschließlich E-Mails, Dateien, Kontakten, sensiblen Daten etc.). Darüber hinaus bieten auch andere von Microsoft bereitgestellte Cloud-Dienste, darunter Produktions- und Entwicklungsumgebungen wie Azure und Visual Tdwyaf, olq ztrmdyvtde Agxwefdwtsc.
