The leading executive arm of the European Union has acknowledged a cyber intrusion after reports indicated that hackers have pilfered extensive data from its cloud storage.

European Commission representative Nika Blazevic informed TechCrunch on Friday that the Commission “identified a cyber-attack, which impacted a portion of our cloud infrastructure.”

“We have swiftly acted and contained the attack. Risk reduction measures have also been put into place. The investigation is ongoing, but we can already confirm that the internal systems of the Commission were not compromised during the cyber-attack,” the spokesperson stated.

In a more detailed announcement on its website, the Commission noted that the breach “impacted its cloud infrastructure that supports the Commission’s web presence on the Europa.eu platform,” which contains a significant amount of the Commission’s website data. 

Bleeping Computer was the first to report the breach on Friday, referencing sources familiar with the situation. The publication indicated that hackers had appropriated hundreds of gigabytes of data, including several databases, from the European Commission’s account on the cloud service provider Amazon Web Services. The hacker shared evidence of their access with the publication, including screenshots.

It remains unclear what specific types of data were compromised.
