Public administration — the week's centre of gravity

The public sector again carried the highest concentration of operationally severe items. France's sovereign Tchap messenger breach (§ 5) struck the French civil service directly; NCSC-CH's Week 23 report documented a coordinated surge in job-seeker targeting against Swiss residents — fake interviews, reshipping identity theft, and LinkedIn-to-GitHub infostealer delivery (NCSC-CH; daily 06-10); and ENISA ran its biennial Cyber Europe 2026 exercise (10–11 June), testing the revised EU Cyber Blueprint and triggering the first live activation of the EU Cybersecurity Reserve (ENISA; daily 06-14). The pattern for a Swiss/EU public-sector SOC: the threats are arriving through identity and through suppliers, and the EU's collective-response machinery is being stress-tested precisely because that is where the pressure is.
