Cyberthreat level remains high – attacks becoming more targeted and complex

The semi-annual report published today by the National Cyber Security Centre (NCSC) outlines the relevant incidents and developments relating to cyberthreats against Switzerland and internationally in the second half of 2025. Alongside voluntary reports of cyber incidents, the report presents reportable cyberattacks against critical infrastructure for the first time. Such attacks have been mandatory reporting requirements since 1 April 2025. Although the number of voluntary reports has remained stable at a high level, the nature of these incidents is evolving and becoming more targeted. Effective protection requires close cooperation between government, businesses and society at both national and international levels.
