UNC5537’s Snowflake data-theft campaign made SaaS identity controls a first-order data platform risk

Mandiant (Google Cloud) reported a financially motivated cluster, UNC5537, systematically accessing Snowflake customer instances using stolen credentials—then stealing data and pursuing extortion and resale.

AWS frames “AI sovereignty” as control-and-choice across the AI stack, highlighting Nitro isolation, Bedrock data-use commitments, and sovereign deployment options

In a Security Blog post, AWS outlines how it approaches “AI sovereignty” as an extension of digital sovereignty, centered on data sovereignty (including residency and operator access restrictions) and operational sovereignty (including resilience and independence). AWS positions its sovereignty offering as “control and choice” across the AI stack—deployment location options (including on-premises and isolated deployments), model/service selection, and governance controls. The post highlights AWS Nitro System isolation properties for EC2 instances (including AI accelerator instances), a commitment that Amazon Bedrock customer inputs/outputs are not used to train Amazon Nova or third-party models, and references third-party validation of Nitro’s design by NCC Group. AWS also notes its ISO/IEC 42001 accredited certification coverage for certain AI services and a 2025 surveillance audit with no findings, framing these as assurance mechanisms for customers with sovereignty and compliance requirements.
