Top Mobile App Threats of 2025: What Half a Million Assessments Reveal

At RSAC 2025, NowSecure co-founder Andrew Hoog presented findings from over half a million mobile app security assessments conducted between January 2022 and February 2025, revealing widespread vulnerabilities in apps from official app stores. The top five risks identified include insufficient resilience against static analysis, with nearly 75% of apps leaving debug symbols in their code, 87% having API discovery issues, and 68% exposing hardcoded URLs. Outdated and insecure encryption methods were prevalent, with over 60% of apps using weak cryptography, such as Triple DES, and practices like reusing initialization vectors and hardcoding encryption keys. Additionally, many apps incorporated untested and vulnerable third-party SDKs, posing further security risks. These findings underscore the critical need for developers to adopt robust security practices and for organizations to rigorously assess the security of mobile applications, even those sourced from trusted app stores.

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...
