Microsoft Launches Cloud Web Applications Threat Matrix

Microsoft has introduced a new threat matrix aligned with the MITRE ATT&CK framework to help organizations understand and mitigate threats to cloud-hosted web applications and serverless platforms. This matrix identifies attack paths that traverse application code, managed runtimes, identities, deployment pipelines, and connected cloud resources. The framework aims to address visibility gaps that arise when investigating applications and their underlying cloud platforms separately. It categorizes attack techniques into tactics such as resource development and initial access, detailing methods adversaries may use to compromise cloud environments. Notably, the matrix highlights risks like subdomain takeover, which can occur when a cloud application is deleted without removing its associated DNS record. This initiative builds on existing threat matrices for Kubernetes and storage services, expanding coverage for cloud web applications. Security teams are encouraged to use this matrix to prioritize hardening and plan investigations effectively.

Key Points: • Microsoft's new threat matrix aligns with MITRE ATT&CK for cloud web applications. • It identifies critical attack paths and techniques affecting cloud-hosted environments. • The matrix helps security teams prioritize defenses and mitigate visibility gaps.
