If your organization relies on AWS IAM Identity Center for workforce access, you can now extend that access across multiple AWS Regions with multi-Region replication. Previously, AWS access portal was only available in one Region, when you add an additional Region, users get an active access portal endpoint there. If the primary Region experiences a […]

As AI agents become part of your development workflows on Amazon Web Services (AWS), you want them to work with your existing AWS Identity and Access Management (IAM) permissions, not force you to build a separate permissions model. At the same time, you need the flexibility to apply different governance controls when an AI agent […]

AWS incident response operates around the clock to protect our customers, the AWS Cloud, and the AWS global infrastructure. Through that work, we learn from a variety of issues and spot unique trends. Over the past few months, high-profile software supply chain threat campaigns involving third party software repositories have highlighted the importance of protecting […]

As we conclude 2025, Amazon Threat Intelligence is sharing insights about a years-long Russian state-sponsored campaign that represents a significant evolution in critical infrastructure targeting: a tactical pivot where what appear to be misconfigured customer network edge devices became the primary initial access vector, while vulnerability exploitation activity declined. This tactical adaptation enables the same […]

Modern web applications built on Amazon Web Services (AWS) often span multiple services to deliver scalable, performant solutions. However, customers encounter challenges when implementing a cohesive HTTP Strict Transport Security (HSTS) strategy across these distributed architectures. Customers face fragmented security implementation challenges because different AWS services require distinct approaches to HSTS configuration, leading to inconsistent […]

December 29, 2025: The blog post was updated to add options for AWS Network Firewall. December 12, 2025: The blog post was updated to clarify when customers need to update their ReactJS version. Within hours of the public disclosure of CVE-2025-55182 (React2Shell) on December 3, 2025, Amazon threat intelligence teams observed active exploitation attempts by […]

The new threat landscape The line between cyber warfare and traditional kinetic operations is rapidly blurring. Recent investigations by Amazon threat intelligence teams have uncovered a new trend that they’re calling cyber-enabled kinetic targeting in which nation-state threat actors systematically use cyber operations to enable and enhance physical operations. Traditional cybersecurity frameworks often treat digital […]

The Amazon threat intelligence teams have identified an advanced threat actor exploiting previously undisclosed zero-day vulnerabilities in Cisco Identity Service Engine (ISE) and Citrix systems. The campaign used custom malware and demonstrated access to multiple undisclosed vulnerabilities. This discovery highlights the trend of threat actors focusing on critical identity and network access control infrastructure—the systems […]

Recently, AWS released Amazon Bedrock API keys to make calls to the Amazon Bedrock API. In this post, we provide practical security guidance on effectively implementing, monitoring, and managing this new option for accessing Amazon Bedrock to help you build a comprehensive strategy for securing these keys. We also provide guidance on the larger family […]

By using Amazon Bedrock AgentCore, developers can build agentic workloads using a comprehensive set of enterprise-grade services that help quickly and securely deploy and operate AI agents at scale using any framework and model, hosted on Amazon Bedrock or elsewhere. AgentCore services are modular and composable, allowing them to be used together or independently. To […]
