ACCORDING to CERT-EU, the European Commission’s Europa web hosting platform on AWS was breached via the Trivy supply chain compromise (CVE-2026-33634), with initial access on 19 March, detection on 24 March, and notification to CERT-EU on 25 March. The breach exposed 340 GB uncompressed (91.7 GB compressed) of data and around 52,000 email-related files, affecting 71 clients including 42 internal European Commission departments and 29 other EU entities.
