Background for this topic.
Cloud computing involves delivering computing services—such as storage, processing, and networking—over the internet using remote data centers. This model enables organizations to scale resources dynamically without owning physical infrastructure. In security terms, the cloud environment is defined by multi-tenant infrastructure where multiple customers share hardware and software resources managed by a cloud provider.
Key security concerns include controlling access through strong identity and access management (IAM), protecting data with encryption both at rest and in transit, and managing vulnerabilities in shared infrastructure components. The cloud’s shared responsibility model requires customers to secure their applications and data while providers secure the underlying platform. Misconfigurations, weak access controls, and insufficient monitoring can expose cloud assets to unauthorized access or data leakage, making precise configuration and continuous security assessment essential.

A large-scale npm supply chain attack compromised over 90 versions of @redhat-cloud-services packages, silently infecting CI/CD environments and developer systems. The malicious code steals credentials from GitHub, cloud platforms, and local machines, then spreads like a worm by republishing trusted packages. Discover how the attack works, what data is at risk, and the steps you can take to protect your organization. The post Preinstall to persistence: Inside the Red Hat npm Miasma credential-stealing campaign appeared first on Microsoft Security Blog.
