Europe’s Cloud Leviathan Pierced: The Alleged 1.6 Million Dossier Exfiltration at OVHcloud

Attackers claim to have compromised OVHcloud’s parent account and exfiltrated 1.6 million customer dossiers and telemetry for 5.9 million domains (including site telemetry, databases, server configs and internal documents) up to March 2026; the threat actors are offering the dataset for auction and seeking intermediaries for a 30% fee, while OVH has not publicly confirmed the breach.
