Microsoft Alerts on AI-Powered Phishing Using LLM-Obfuscated SVG Files

Microsoft has identified a sophisticated phishing campaign targeting U.S. organizations where threat actors used code likely generated by large language models to hide malicious behavior inside an SVG file. The attackers compromised a business email account and sent messages masquerading as file-sharing notifications. The SVG file appeared to be a benign PDF but contained obfuscated payloads using business vernacular and synthetic structure to evade email security tools. The campaign reflects a growing trend of blending AI tools into attack workflows—for crafting more convincing phishing lures, automating malware obfuscation, and mimicking legitimate content.

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...
