European Commission Probes Cloud Breach After Hacker Targets Amazon Infrastructure

The European Commission is investigating a fresh cybersecurity breach after attackers gained access to part of its cloud infrastructure hosted on Amazon raising new concerns about how even high-security government systems are being targeted.

According to reports, the breach involved at least one compromised account used to manage the Commission’s cloud environment. While details remain limited, sources say the intrusion was detected quickly and is now under active investigation by the EU’s cybersecurity response teams. 

What makes the incident particularly alarming is the scale of the alleged data exposure. The threat actor behind the attack claims to have exfiltrated more than 350GB of data, including databases and internal files, and has shared screenshots as proof of access to employee information and internal systems. 

In a twist that underscores how cyberattacks are evolving, the attacker reportedly does not plan to demand a ransom. Instead, they say the data will be released publicly at a later date an approach that shifts the impact from financial extortion to reputational and geopolitical risk. 

Importantly, there’s no indication that Amazon Web Services itself was compromised. Instead, the breach appears to have targeted the management layer specifically accounts controlling access to the cloud environment. That distinction matters: it reflects a growing trend where attackers bypass hardened infrastructure and instead exploit credentials, misconfigurations, or weak access controls. 

This isn’t an isolated incident. Earlier this year, the Commission disclosed another breach involving its mobile device management systems, part of a wider wave of attacks hitting European institutions through vulnerabilities in enterprise software. 

The timing is awkward for Brussels. The European Commission has been actively pushing stricter cybersecurity regulations and greater digital sovereignty across the bloc, including increased scrutiny of cloud providers and critical infrastructure resilience. A breach inside its own systems even if limited adds pressure to those efforts.

For the broader industry, the takeaway is clear: cloud security is no longer just about infrastructure. Identity, access, and account-level controls are becoming the new frontline and increasingly, the weakest link.

If confirmed, the incident will likely fuel ongoing debates about who is ultimately responsible for securing cloud environments: the provider, or the customer operating within it.
