Supply-Chain Attacks Are Exploiting Our Assumptions

The article argues that modern software development relies on a set of implicit trust assumptions—about package origin, maintainer integrity, build provenance, and distribution chains—that attackers are increasingly undermining. It reviews recent attack vectors such as typosquatting, credential theft, build pipeline poisoning, and malicious maintainers gaining control. To counter these threats, defenders are developing tools and practices like typo-resistance checks (TypoGard/Typomania), static workflow analyzers (Zizmor), trusted publishing with attestations (e.g. in PyPI), Homebrew build provenance, and capability analysis (Go Capslock). The author calls on ecosystems and developers to shift from implicit trust to explicit, verifiable assurances across the software supply chain.

KEVIntel: Real-Time Intelligence on Exploited Vulnerabilities

KEVIntel is a dynamic platform providing up-to-date information on known exploited vulnerabilities (KEVs). It aggregates data from over 50 public sources, including CISA, and enriches each entry with metadata such as EPSS scores, online mentions, scanner inclusion, and exploitation status. The platform aims to serve as an early warning system, offering insights even before official publications. KEVIntel supports various formats like JSON, CSV, and RSS, facilitating integration into security operations. These entries include CVSS scores, exploit status, and links to proof-of-concept code, aiding organizations in prioritizing remediation efforts.   https://kevintel.com/

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
