Malicious Open-Source Packages Use Trojanized Patches to Infect Local Software

A recent report by ReversingLabs highlights a new tactic employed by cybercriminals involving malicious open-source software packages that apply Trojanized patches to legitimate software already installed on users' machines. One such package, "pdf-to-office," was found on the npm repository, masquerading as a tool for converting PDFs to Office documents. Upon execution, it ran an obfuscated JavaScript file named "pdftodoc," which searched for popular cryptocurrency wallets like Atomic and Exodus. If detected, it replaced legitimate files with compromised versions, effectively compromising the user's system. This approach allows attackers to bypass traditional defenses by targeting trusted software post-installation, marking a shift in software supply chain attack strategies.

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...
