## EU Europa Platform Breach: 350GB Data Exfiltrated Due to Critical IAM Misconfigurations
A new technical analysis of the European Commission's 'Europa' platform breach reveals the incident is far more severe than first disclosed, with up to 350GB of data exfiltrated, not the initially reported 90GB. The core failure was a catastrophic misconfiguration of Identity and Access Management (IAM) systems, allowing attackers to bypass critical security controls and extract a massive data volume.

The breach analysis points to three critical technical failures. First, the attackers stole DKIM signing keys, resulting in a total loss of email authenticity for EU domains, enabling perfect impersonation that bypasses DMARC protections. Second, the 'skeleton' of their AWS Organizations structure was exposed, likely due to a lack of proper Service Control Policies (SCPs). Third, and most critically, IAM failures included over-privileged roles with wildcard permissions (Resource: '*') and a failure to enforce IMDSv2, which together created the pathway for the 350GB exfiltration.

The scale of the failure is starkly ironic for the institution that enforces the General Data Protection Regulation (GDPR) across Europe. The breach represents a masterclass in cloud security missteps, raising serious questions about internal security governance and compliance at the highest levels of the EU's digital infrastructure. The exposure of such fundamental IAM and cloud hygiene flaws in a major governmental platform signals systemic risk and will prompt intense scrutiny from data protection authorities and cybersecurity experts.
