LONDON

The European Commission on Friday said it is investigating a cyberattack that targeted part of its online infrastructure earlier this week.

In a statement, the Commission said the incident was discovered on March 24 and affected its cloud infrastructure used to host websites on the Europa.eu platform. Officials said immediate action was taken to contain the attack.

The Commission added that its “swift response ensured the incident was contained” and that measures were put in place to mitigate risks to services and data. It said the availability of Europa websites was not disrupted.

Early findings suggest that data may have been taken from the affected websites. The Commission said it is notifying EU bodies that could have been impacted, while an investigation into the full extent of the breach continues.

It stressed that its internal systems were not affected by the attack.

The Commission said it will continue to monitor the situation and take further steps to safeguard its systems and data. It also plans to analyze the incident to strengthen its cybersecurity capabilities.

The statement comes amid growing concern over cyber and hybrid threats across Europe, particularly those targeting essential services and democratic institutions.

The Commission said it is working to improve the EU’s resilience to such attacks.
