NSA's Equation Group: A Chinese Perspective on Cyber Operations

In February 2025, InverseCos published an article titled "An Inside Look at NSA (Equation Group) TTPs from China’s Lens," which examines alleged cyber activities of the NSA's Equation Group, referred to by Chinese cybersecurity entities as "APT-C-40." The article aggregates insights from Chinese sources, including Qihoo 360, Pangu Lab, and the National Computer Virus Emergency Response Center (CVERC), focusing on the reported 2022 cyberattack on China's Northwestern Polytechnical University. According to these reports, the NSA's Tailored Access Operations (TAO) unit deployed over 40 unique malware strains to conduct data theft and espionage. Attribution methods cited include analysis of attack timings aligning with U.S. working hours and identification of American English language settings and keyboard usage. The article notes that these allegations remain unverified by independent sources and aims to share perspectives from Chinese cybersecurity research.

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...
