[English<\/a>]Es ist eine merkw\u00fcrdige Geschichte, die momentan in den Medien aufgegriffen wird. Android-Nutzer bekommen in ihren Messenger-Apps Push-Benachrichtigungen mit dem Text 'Test'. Aktuell ist wohl unklar, woher diese Nachrichten kommen – von Fehlfunktion bis hin zum Hack reicht die Spekulation.<\/p>\n

<\/p>\n

Microsoft untersucht den Fall<\/h2>\n

\"\"Mir ist vor einigen Stunden bereits ein Tweet<\/a> des Microsoft 365 Social Media Teams @MSFT365Status aufgefallen, die angeben ein Problem zu analysieren. Nutzer w\u00fcrden die Nachricht 'Test' auf ihren Ger\u00e4ten erhalten. Sp\u00e4ter hie\u00df es, dass es Android-Ger\u00e4te betreffe.<\/p>\n

\"@MSFT365Status<\/p>\n

Im letzten Statuseintrag hei\u00dft es, dass die Ursache gefunden wurde und man Abhilfema\u00dfnahmen eingeleitet habe. Martin Geu\u00df von Dr. Windows hat diesen Artikel<\/a> zum Thema ver\u00f6ffentlicht. Er bekommt in seiner Teams-App folgende Push-Benachrichtigungen – andere Teams-Anwender erleben das Gleiche.<\/p>\n

\"Test-Benachrichtigung(Quelle: Dr. Windows)<\/p>\n

Der Absender der Test-Benachrichtigung ist 'FCM Messagess', was wegen der Schreibweise doch arge Bedenken hervorruft. Martin schreibt, dass sp\u00e4ter neue Benachrichtigungen mit dem Text \"Testing notification from Microsoft to investigate the problem\" erschienen.<\/p>\n

Das K\u00fcrzel FCM steht f\u00fcr Firebase Cloud Messaging. Dieser Google-Dienst wird auch von Microsoft f\u00fcr Push-Benachrichtigungen genutzt. heise schreibt hier<\/a>, dass auch andere Dienste wie Google-Hangouts solche Benachrichtigungen erhalten. Google, Microsoft und weitere Nutzer des FCM-Dienstes begannen die Vorf\u00e4lle zu untersuchen. Gem\u00e4\u00df der Meldung in obigem Tweet durch Microsoft sollte das Problem inzwischen aber behoben sein.<\/p>\n

Hier noch einen Auszug aus dem Administrator Statusbereich, den mir Blog-Leser Andreas P. zukommen lie\u00df.<\/p>\n
