Das Bundesamt f\u00fcr Sicherheit in der Informationstechnik (BSI) warnt, dass in Deutschland mehr als 30.000 veraltete Microsoft-Exchange-Server (inkl. 2016\/2019 und \u00e4lter) weiterhin mit offenem Outlook Web Access im Internet betrieben werden. Nach dem Support-Ende am 14. Oktober 2025 erhalten diese Systeme keine Sicherheitsupdates mehr und bleiben dauerhaft anf\u00e4llig f\u00fcr neu entdeckte Schwachstellen. Betroffen sind Unternehmen, Krankenh\u00e4user, Schulen, Stadtwerke, Kommunen und weitere Organisationen.<\/p>\n

Das BSI betont, dass Betreiber, die trotz ausreichender Vorlaufzeit nicht auf aktuelle Software umsteigen, fahrl\u00e4ssig handeln; bei erfolgreichem Angriff k\u00f6nnen Netzwerke komplett kompromittiert werden. Als Schutzma\u00dfnahme empfiehlt die Beh\u00f6rde die Umstellung auf aktuelle Versionen oder die Migration auf Alternativen; ein m\u00f6glicher Pfad ist die Exchange Subscription Edition (SE), die On-Premises betrieben werden kann. Verantwortliche m\u00fcssen z\u00fcgig handeln, andernfalls bleibt oft nur die Abschaltung der Anwendung zur Abwehr neuer Schwachstellen.<\/p>\n
