Hacker Group Rhysida Releases Data from Berlin

Berlin: The hacker group Rhysida has released more than a million data records from a cyberattack on the Berlin state administration. The attack occurred several weeks ago when the group demanded a ransom of around two million euros. The Senate of Berlin decided not to comply with the demands, prompting the hackers to follow through on their threat. The released data includes personal information of citizens as well as internal documents of the administration. Experts estimate that the data pertains to over 500,000 affected individuals.

The exact nature of the data ranges from addresses and birth dates to sensitive information regarding social benefits. The Berlin authorities have responded promptly and initiated an investigation into the incident. The Senate has also engaged the state’s cyber security agency to assess the impact of the attack and implement further security measures. A spokesperson for the agency stated that the safety of citizens is the top priority. The hacker group Rhysida is known for its aggressive tactics and has previously conducted similar attacks on other institutions.

The group frequently uses ransomware to extort its targets. Experts warn that such attacks may increase in the future, particularly against public institutions. The data release also has legal implications. Data protection experts point out that the Berlin administration may have violated the General Data Protection Regulation (GDPR) by not adequately protecting against data loss. This could lead to significant penalties if it is proven that the administration acted negligently.

Reactions from the political sphere are mixed. While some politicians support the Senate's decision not to pay, others are calling for a review of the security measures within the administration. An opposition member stated that citizens have a right to the protection of their data and that the administration has failed. The hacker group has announced that it will release more data if its demands are not met, which could further exacerbate the situation for the affected citizens.

Authorities are advising citizens to remain vigilant and monitor their personal data to prevent potential identity theft. The Berlin police have established a special commission to investigate the incident. Investigators are working closely with cyber security experts to clarify the circumstances of the attack and identify the perpetrators. However, there are currently no concrete leads on the identity of the hackers. The incidents in Berlin are part of a larger trend of increasing cyberattacks on public institutions.

According to a report from the Federal Office for Information Security (BSI), there was a 30% increase in cyberattacks on government institutions in 2025 compared to the previous year. This development raises questions about the security and resilience of digital infrastructure. The Berlin administration has announced plans to revise its security strategies and invest in new technologies to prevent future attacks. A spokesperson for the administration emphasized the intention to learn from this incident and raise security standards. The data release also has implications for the affected citizens.

Many of them are concerned about the safety of their personal information and the potential consequences of identity theft. The administration has announced that it will provide support for those affected to inform them about the next steps. The hacker group Rhysida has previously made headlines with similar attacks. Their methods and the nature of the attacks have raised concerns within the cyber security community.

Experts warn that such groups are becoming increasingly sophisticated, making it more difficult for authorities to combat them. The Berlin administration has announced a comprehensive analysis of the security vulnerabilities that led to this incident by September 30, 2026. The results are to be presented to the public to create transparency and regain citizens' trust.
