Cybersicherheit : Wie sicher ist die Schul-IT?

Lehrer und Schüler an Karlsruher Schulen mussten zwischen Mitte Februar und Mitte März zeitweise offline arbeiten. Die Server von acht Schulen waren einem Cyberangriff zum Opfer gefallen. Die Angreifer hatten sie mit Ransomware verschlüsselt und laut Medienberichten ein Lösegeld von zwei Bitcoin pro Schule verlangt, was nach damaligem Kurs 41.000 Euro entsprach. Die Stadt trennte daraufhin 77 Schulen sowohl vom Verwaltungsnetz als auch vom pädagogischen Netz, um zu prüfen, ob weitere Einrichtungen vom Angriff betroffen waren.
