What happened
The European Commission is investigating a breach after a threat actor gained access to at least one of the organization’s Amazon Web Services accounts. The incident has not yet been publicly disclosed by the European Commission, but the attack was reportedly detected quickly and is now under investigation by the Commission’s cybersecurity incident response team. The threat actor claimed to have stolen more than 350 GB of data, including multiple databases. The actor also provided screenshots showing access to information belonging to European Commission employees and to an email server used by Commission staff. According to the claim, the actor does not plan to extort the European Commission with the allegedly stolen data but instead intends to leak it online at a later date. AWS said it did not experience a security event and that its services operated as designed.
Who is affected
The direct exposure appears to affect the European Commission, including information belonging to European Commission employees and an email server used by Commission staff. The article does not specify how many employees or records were affected.
Why CISOs should care
This incident is relevant because it involves unauthorized access to a cloud environment used by a major public-sector institution and a claimed theft of more than 350 GB of data. It also shows the governance and response pressure that follows when an intrusion is detected before public disclosure is made.
3 practical actions
- Validate affected cloud accounts quickly: Confirm exactly which cloud accounts, datasets, and email infrastructure were accessible so leadership is working from a verified exposure scope.
- Separate provider assurance from customer compromise: Treat statements from a cloud provider about its own services operating as designed as distinct from the possibility that a customer account was still breached.
- Prepare for leak-driven response: Align legal, communications, and security teams early when an actor claims stolen data will be leaked rather than used for extortion.
