Berlin Senate Administrations Recover After Cyberattack
Berlin’s Senate administrations are now fully operational again after a significant hacker attack forced two key departments offline for several days. The attack, discovered on August 14, 2026, targeted the Senate Department for Urban Development, Construction and Housing, and the Senate Department for Mobility, Traffic, Environment and Climate Protection. Both were swiftly disconnected from the state network to limit further damage, resulting in restricted services and internal communication issues [Source 1][Source 2][Seed Article].
The immediate consequence of the attack was that these administrations could no longer send external emails and were only reachable via telephone. This disruption also impacted related welfare payments, such as housing benefits (Wohngeld) and support programs for children and youth activities, delaying their processing [Source 1][Source 4].
Impact on Expats and International Residents in Berlin
For expatriates, international students, and foreign workers living in Berlin, the disruption had practical consequences. The services related to housing support and social welfare benefits experienced delays, potentially affecting rent assistance and child-related subsidies. Those relying on official communication from these departments faced difficulties, as email contact was unavailable and processing times extended. Expats should stay informed via telephone lines and consider early application or renewal of benefits where possible to avoid delays. Monitoring announcements from authorities remains important as investigations continue [Source 1][Source 4].
Authorities confirmed no sensitive personal data had definitively been compromised at the time, though investigations by the Berlin State Criminal Police and Public Prosecutor’s Office are ongoing to clarify the scope and source of the attack. External cybersecurity experts, including a US-based firm, are assisting in crisis management [Source 2][Source 4][Source 3].
The hacker attack involved an intrusion into Berlin’s state IT network, with forensic findings described as an “incriminating” impact on the Landesnetz (state network). The exact attacker identity remains unknown, and official inquiries continue. Berlin’s Chief Digital Officer Florian Hauer emphasized the seriousness of the incident and that affected administrations, while operational, faced significant constraints due to lack of internet access [Source 3][Source 6].
Technical restoration took several days, with Berlin’s governing mayor Kai Wegner stating that full reconnection of the impacted departments could take additional days beyond initial estimates, underscoring the complexity of resolving such attacks [Source 2].
