Supply-chain attacks compromise trusted vendors or dependencies, potentially reaching downstream systems; verify provenance and limit access before deployment.

Background for this topic.
Supply chain is the network of suppliers, software developers, service providers, components, and processes used to build and deliver an organization’s products or services. In a security threat model, it extends the trust boundary beyond the organization: a compromised supplier account, build system, software dependency, update mechanism, or hardware component can introduce malicious code, expose credentials, or undermine systems used by many customers.
Effective protection starts with mapping critical suppliers, dependencies, data flows, and access, then applying risk-based due diligence and least-privilege, segmented access. For software, maintain an inventory such as a software bill of materials, verify signed artifacts and update provenance where feasible, and monitor dependencies for vulnerabilities or unexpected changes. Contracts and technical controls should support timely notification and investigation. Response plans should cover revoking supplier access, isolating affected versions or integrations, determining exposure, and coordinating remediation with the provider.
Microsoft's GitHub repositories have become the latest to fall victim to the ongoing Miasma self-replicating supply chain attack campaign
Multiple software supply chain attacks have hit the npm ecosystem, with threat actors using both malicious and poisoned versions of over 50 legitimate packages to distribute a Rust-based information stealer and a self-spreading worm, respectively
Like Shai-Hulud, the campaign targets developers to steal credentials and reuses them to propagate across the software supply channel.

A surge in real-world attacks against agentic AI systems is reshaping how we think about risk. Based on 12 months of red teaming, this update introduces seven new failure modes, from supply chain compromise to goal hijacking, and the practical mitigations teams need now. The post Updating the taxonomy of failure modes in agentic AI systems: What a year of red teaming taught us appeared first on Microsoft Security Blog.
A new supply-chain attack has infected 36 packages on the Node Package Manager (npm) index with infostealer malware called IronWorm. [...]
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.
