The figure was announced by the Federal Office for Cybersecurity on Monday in its report on the second half of 2025. Around a quarter of the reported incidents came from the administrative sector.

This was followed by IT and telecommunications companies as well as banks and insurance companies. Around one in five reported attacks was related to hacking. Some 16% were so-called DDoS attacks. This was followed by the theft of access data, malware, data leaks and blackmail software (ransomware).

Tens of thousands of cyber incidents were reported voluntarily, most of them by private individuals. In total, the Federal Office for Cybersecurity registered almost 65,000 reports in 2025. The figures were stable in comparison at a high level, it said. In the previous year, it received around 63,000 reports.
