Berlin Cyberattack Puts Housing Benefits for 50,000+ Households at Risk
More than 50,000 Berlin households risk not receiving their housing benefit payments on time following a hacker attack on the city government’s information systems. The disruption has affected not only benefit payments, but also housing application processing, other social programs, and portions of the city’s public-facing internet services.
Two Senate Departments Disconnected From the City Network
The disruption began after an attack targeted the Berlin Senate Department for Urban Development, Building, and Housing, along with the Senate Department for Mobility, Transport, Climate Protection, and the Environment. On Friday, both departments were disconnected from the shared city network to prevent the attack from spreading further. As a result, employees lost access to the internet and external email, and remote work became impossible. Internal mail and telephone systems remained partially functional.
District Housing Offices Hit Hardest
The consequences proved especially severe within the city’s district housing offices. The system employees use to process housing benefit applications, social housing certificates, and other related services stopped functioning entirely. The districts of Pankow, Marzahn-Hellersdorf, and Friedrichshain-Kreuzberg all confirmed disruptions. Housing benefits are typically disbursed at the end of the month, so authorities are now searching for ways to process upcoming payments while bypassing the inaccessible system.
Education and Participation Program Payments Also Threatened
Payments under the “Bildung und Teilhabe” (Education and Participation) program – which helps children from low-income families cover the cost of school lunches, field trips, sports activities, and other expenses – are similarly at risk. Officials in Pankow warned that processing the corresponding applications and disbursing funds is currently impossible. It remains unclear when the system will be restored.
Ripple Effects Beyond the Two Directly Affected Departments
The consequences of the attack have extended well beyond the two departments initially compromised. Following the incident, specialists began a large-scale review of the entire city network. According to RBB, this review is consuming a significant portion of network resources, causing certain other government services to run slowly or become entirely unavailable. Notably, this has created difficulties for residents attempting to submit applications online and request mail-in voting documents ahead of the September 20 election for the Berlin House of Representatives.
Scope of the Breach and Attribution Remain Unclear
It remains unclear precisely which systems were compromised and who is responsible for the attack. The Senate maintains that no confidential information has been stolen. Based on available evidence, attackers only obtained geographic information data that was already publicly accessible. However, RBB’s sources had previously reported that sensitive data may have been stolen, so the investigation remains ongoing. Authorities are also determining whether the attack affected any other city departments.
Investigation and Emergency Response
The case is being investigated by the Berlin State Office of Criminal Investigation, the Berlin public prosecutor’s office, and Germany’s Federal Office for Information Security. To manage the fallout, an emergency task force has been assembled under the leadership of Berlin’s Commissioner for Information Security. Authorities have not yet disclosed details regarding how attackers gained access to the system or which vulnerability was exploited.
On August 19, Berlin authorities plan to hold a separate briefing detailing the full scope of the attack and further response measures. The press conference is expected to include Governing Mayor Kai Wegner, Senator for the Interior Iris Spranger, State Secretary for Digitalization Florian Hauer, and Information Security Commissioner Olaf Kroll-Peters.
