Cacheract: Exploiting GitHub Actions Cache Vulnerabilities

In his December 21, 2024, blog post, Adnan Khan introduces Cacheract, an open-source proof-of-concept tool that exploits misconfigurations in GitHub Actions caching. Building on his earlier research into cache poisoning, Khan developed Cacheract to automate the injection of malicious code into build caches, allowing malware to persist across multiple workflow runs. The tool works by predicting and replacing cache entries, enabling unauthorized actions within continuous integration and deployment pipelines. Khan emphasizes that Cacheract is intended for ethical security research and highlights the risks of insecure caching configurations in CI/CD environments.

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...
