IT researcher Waidner: 'The circle of those who can carry out such an attack is growing'

Professor Waidner, ein IT-Forscher, kommentiert den Hackerangriff auf die Berliner Verwaltung und betont, dass der Kreis der potenziellen Angreifer sich erweitert. Er warnt davor, den Vorfall als 'GAU' einzustufen, da schlimmere Szenarien möglich sind, etwa Angriffe auf kritische Infrastrukturen wie Krankenhäuser oder Wasserversorgung. Der Angriff führte dazu, dass zwei Senatsverwaltungen vom Landesnetz isoliert wurden, wohnungsfördernde Anträge mehrere Wochen nicht bearbeitet werden konnten und über 50.000 Haushalte betroffen waren. Vertrauliche Daten wurden im Darknet veröffentlicht, was die Schwachstellen der Verwaltungs-Digitalisierung ohne ausreichende Sicherheitsmaßnahmen offenlegt. Die veröffentlichten Daten umfassen 5,8 Terabyte, darunter personenbezogene Daten, Passwörter und sensible Dokumente. Waidner erklärt, dass sogar scheinbar harmlose Daten, wie Adressinformationen, für Cyberkriminelle nützlich sein können, um gezielte Phishing-Angriffe zu starten. Er nennt als Beispiel die Fitness-App Strava, deren Daten zur Identifizierung militärischer Stellungen genutzt wurden. Obwohl der Senat behauptet, dass bundesweite Sicherheitsdokumente nicht betroffen seien, gibt es Ber报道

Professor Michael Waidner, head of the Fraunhofer Institute for Secure Information Technology (SIT) and chair of cybersecurity at TU Darmstadt, warned that “the circle of those who can carry out such an attack is growing.” The hacker group Rhysida launched a ransomware attack on Berlin’s municipal administration, leading to the separation of two Senate departments from the state network. For weeks, housing benefit applications could not be processed, affecting more than 50,000 households. Initially, officials claimed no sensitive data had been leaked, but later reports indicated that confidential information was published in the dark web. The attackers released approximately 5.8 terabytes of data, though the exact nature and sensitivity of the contents remain unclear. According to journalists' analyses, the data includes around 46,500 contracts, nearly 78,000 administrative cases, 27,000 employee records, and salary statements. While the Senate has confirmed some of these details, it has not disclosed whether highly sensitive information, such as defense strategies or critical infrastructure plans, was compromised. Waidner emphasized that even seemingly harmless data can pose serious risks when combined with other information. He cited the example of the fitness app Strava, whose training maps inadvertently revealed military bases and patrol routes. This highlights how easily personal data can be exploited for malicious purposes. Despite concerns over national security, the Senate stated that federal institutions were unaffected, and the allegedly classified documents related to civil protection and defense were not deemed security-critical. However, media reports suggest that around 8,000 files involving critical infrastructure might have been exposed. Waidner noted that the tools used in such attacks are becoming increasingly accessible due to artificial intelligence, making cyber threats more pervasive. Rhysida, known for its double extortion model, encrypting data and threatening to leak it unless paid, is linked to several high-profile attacks, including those on the British Library and healthcare providers. The Berlin attack fits this pattern, targeting public administration, healthcare, and education sectors.
