What Happened
On March 27, 2026, the European Commission confirmed a cyberattack on its cloud infrastructure hosting Europa.eu websites. Hackers reportedly accessed the Commission's Amazon Web Services account and stole over 350 gigabytes of data before the breach was contained. The Commission has stated that its internal systems were not affected, and the investigation is ongoing to determine what specific data was compromised. The organization is notifying EU entities that may have been impacted by the incident.
Who Is Affected
The breach affected entities that use or have data stored on Europa.eu platform websites, which host much of the European Commission's public web presence. Early findings suggest data was taken from these websites, and the Commission is notifying Union entities who might have been affected. This incident follows a separate February 2026 breach that exposed employee names and mobile numbers, though it remains unclear if individual employee data was compromised in this latest attack.
Why It Matters
This incident demonstrates that even major government institutions with significant cybersecurity resources remain vulnerable to cloud infrastructure attacks. The breach of an EU executive body's cloud systems raises concerns about the security of government data stored with third-party cloud providers and highlights ongoing challenges in identity and access management for cloud accounts. The incident occurs shortly after the Commission introduced new cybersecurity measures in January 2026, underscoring the persistent difficulty of protecting critical digital infrastructure.
What You Should Do
If you are an EU entity that maintains a web presence on Europa.eu or shares data with the European Commission through this platform, monitor communications from the Commission regarding whether your data was affected. Change passwords and review access permissions for any accounts connected to Commission systems. If you receive notification that your data was compromised, consider what sensitive information may have been exposed and take appropriate steps such as monitoring for phishing attempts or unauthorized use of that information.
