BSI declares first attack vector on Berlin authorities

The Federal Office for Information Security (BSI) has warned about a new cyberattack campaign named 'TerminalFix' targeting Berlin's administrative departments. The attack, linked to the cybercriminal group Rhysida, led to significant data leaks and disrupted critical services. The breach began in mid-August 2026 and affected two Senate administrations responsible for urban development, construction, mobility, environment, and climate protection. On August 14th, these agencies were disconnected from the state network, causing issues such as the inability to pay housing benefits to 50,000 households. By August 24th, all systems were restored, but authorities confirmed data had been stolen, though details remained undisclosed. On August 28th, the Berlin government rejected ransom demands, while reports suggested the attackers might have accessed sensitive documents including over 46,500 contracts. Experts warn of potential identity theft and fraud.

Berlin: Hacker group Rhysida released another data package from the leak A further data package from the large-scale cyberattack on the Berlin Senate administration was published overnight into Sunday, according to the Senate in the capital city. This was announced by the Senate on Sunday. Following the initial publication of stolen information on Friday, measures taken were again “reviewed in some aspects” to enhance security. Additional measures could lead to temporary restrictions when using specialized procedures in the building administration, stated the Senate chancellery. “All users will be informed,” the chancellery added. The effects could also affect citizens, said a Senate spokesperson in response to a query from dpa. She did not specify which specialized procedures were affected or what exact measures had been implemented. A specialized procedure includes applying for and receiving housing benefits. The criminal hacker group Rhysida gained unauthorized access to parts of the Berlin municipal network between August 7th and 12th and stole data. The affected departments were the Senate administrations for Construction and Transport. The administration became aware of the attack on August 14th and made it public three days later. The hackers demanded two million euros in Bitcoin ransom, with payment due by Friday. However, the Berlin state government stated it would not pay and refused the demand. After the deadline passed on Friday, around 1.4 million files were made available for download. BSI warns of increased threat level after cyberattack on Berlin administration After the release of data from the Berlin administration by cybercriminals, the Federal Office for Security in Information Technology (BSI) pointed to an increased threat level. According to a spokesperson, there could be “various risks for the affected individuals and ultimately for society” resulting from the publication of stolen data. The BSI specifically highlighted the possibility of targeted phishing attacks following the data breach. People who had contact with affected persons or institutions should therefore be particularly vigilant. Possible hack-and-leak operations In the political sphere, there is a particular risk of so-called hack-and-leak operations, especially before elections. These involve publishing stolen documents, emails, or similar information at a time favorable to the attacker, often placing them in a false context. Elections for a new parliamentary house in Berlin are scheduled for September 20th. However, the BSI does not assume that the criminals behind the attack have political motives. It assumes the act was “exclusively financially motivated.” Information regarding critical infrastructure “The additional data may contain information about critical infrastructure, companies, and organizations, which can increase the threat level depending on the sensitivity of the data,” warned the BSI. Affected parties should check whether they are directly impacted and what type of data has been published, and consider changing processes accordingly. Berlin’s mayor, Kai Wegner, told the Bild newspaper that current efforts are being made to determine which information has flowed out. The goal is to reach affected individuals as quickly as possible. Wegner had previously revealed that the city state was under pressure after a cyberattack became known two weeks earlier. The criminal hacker group Rhysida demanded a ransom of 30 Bitcoins, equivalent to roughly two million euros. The Senate rejected this demand. 5.8 terabytes of data in the dark web After the deadline on Friday afternoon, the hacker group fulfilled its threat: a 5.8 terabyte data package was published in the dark web. The group itself stated it had stolen approximately 1.44 million individual files. Among these are more than 5,000 personal records, fine collection cases, and salary statements, as well as confidential documents from federal council committees and vulnerability analyses of the Berlin water supply system. Additionally, the attackers boasted of having obtained login credentials and passwords in plaintext, for example, for databases of the administration and payment service providers. Whether these claims are accurate remains unclear. Federal data systems not affected A government spokesperson stated that the federal government is closely monitoring the flow of information and investigations into the data breach at the state level. The involved authorities, including the BSI, the Federal Criminal Police Office, and the Federal Intelligence Service, are continuously cross-checking their information. “After analyzing potential security risks, appropriate measures to ensure military security will be initiated,” the spokesperson said. “At the current stage of knowledge, federal data systems are not affected,” the spokesperson added. Damage analysis will take several weeks The consequences of the cyberattack on two Berlin Senate administrations will keep IT technicians busy for some time. Digital State Secretary Florian Hauer (CDU) said on Monday afternoon in the House of Representatives committee that the Berlin state is still working to forensic examine all IT systems of the state and districts. This includes checking whether the hackers are still hiding within the state network and capable of further attacks. This investigation will “take several days.” The administrative authority is also examining how much damage the hackers caused. They have stolen over 1.2 million files with a volume of 5.7 terabytes. Their loot was published in the dark web on Friday. On Monday afternoon, IT technicians were still downloading everything. Why does the download take so long? This takes several days because of the limited bandwidth available for such transfers. President of the BSI, Claudia Plattner, said in the committee that this is not unusual: The hackers stored the data on illegal servers that were small and “well hidden.” They allowed only a slow data flow. Once the experts have downloaded the files, they will sort through them using artificial intelligence to identify potentially sensitive content. Then administrative staff will review the contents and identify all victims of the data theft. Plattner said this damage analysis will “take several weeks.” Through research by journalists in the dark web, it has become known that in addition to personal data of employees, emergency plans for protecting critical infrastructure were also stolen. State Secretary Hauer said in the committee that files serving “collective safety” would be prioritized. At present, he does not expect the “national defense capability” to be threatened by the theft. Connection to Russia likely Behind the cyberattack is the hacker collective Rhysida. It first appeared in May 2023. Who is behind it remains unknown. Due to the sophisticated attack patterns, industry observers assume Russian hackers are involved. Also, no Russian or pro-Russian entities have been attacked yet. Half of their previous targets are located in the United States, and about a quarter in Europe. Rhysida offers hacking software along with services, including ransomware-as-a-service (RaaS). RaaS can be rented by cybercriminals. It contains an encryption program used to lock data, typically putting the owners in digital hostage situations. Data is only released upon payment of a ransom. Berlin had “luck in misfortune” Both Hauer and Plattner evaluated it as “luck in misfortune” that the attack was discovered in Berlin before the hackers began encrypting the data. They could only copy the data. Thus, the data is still available in the Senate administrations. Despite this, the hackers tried to extort money: They demanded thirty Bitcoin, equivalent to about two million euros. In mid-August, they set a deadline for the Senate to pay within one week. Otherwise, everything would be published in the dark web. The black-red Senate did not agree to this with the approval of the opposition. Thus, the data landed in the net on Friday. Rhysida has already emerged multiple times with its extortion method: in May 2023 on the servers of the Hochschule Kaiserslautern and shortly thereafter at the American health authority, in autumn 2023 at the British Library and the King Edward VII's Hospital in London, and in spring 2026 at the Stuttgart administration.

Slice by Slice: How bad is data theft in Berlin really?

A major data breach has occurred in Berlin, where a hacker group known as Rhysida gained access to large amounts of data from two Senate departments between August 7th and 12th, 2026. The breach was initially discovered on August 14th when the departments were isolated from the state network. The attack began much earlier, with the hackers gaining unauthorized access through a phishing email sent to a staff member of the Senate Department for Transport. This led to the download of malicious software, allowing the hackers to maintain persistent access to the system. Rhysida is described as a ransomware ecosystem linked to Russian-speaking actors, known for targeting public institutions and demanding cryptocurrency payments. In this case, the group demanded 30 Bitcoin (approximately 2 million euros) or threatened to release 5.7 terabytes of stolen data.

Digitalisation: the bear's share

The article uses a fable by Jean de La Fontaine, 'Der Bär und der Gartenfreund,' to metaphorically describe a cyberattack on Berlin's administrative systems. The attack, which began at least in early August, led to the leakage of approximately one million data records from two Senate departments. Initially, the breach was unnoticed, but it was eventually discovered, revealing that the attack had been ongoing for some time. As a result, these departments were temporarily disconnected from the city’s network, disrupting services like welfare payments to around 50,000 households. After several days, the affected authorities regained internet access. Officials initially downplayed the incident, claiming that the leaked data were already publicly accessible. However, subsequent investigations revealed that more data might have been compromised, leading to concerns over cybersecurity and potential involvement of foreign actors.
