CISA, NSA, and Global Partners Release a Shared Vision of Software Bill of Materials (SBOM) Guidance
Sep 3, 2025
CISA, in collaboration with NSA and 19 international partners, released joint guidance outlining A Shared Vision of Software Bill of Materials (SBOM) for Cybersecurity. This marks a significant step forward in strengthening software supply chain transparency and security worldwide. An SBOM is a formal record detailing the components and supply chain relationships used in building software. SBOMs act as a software “ingredients list” providing organizations with essential visibility into software dependencies, enabling them to identify components, assess risks, and take proactive measures to mitigate vulnerabilities. The guidance highlights the benefits of SBOM adoption for software producers, purchasers, operators, and national security organizations. Key advantages include reducing risks, improving vulnerability management, and enhancing overall software security practices. By promoting transparency, aligning technical approaches, and leveraging automation, SBOM adoption strengthens the resilience of the global software ecosystem. This guidance urges organizations worldwide to integrate SBOM practices into their security frameworks to collaboratively address supply chain risks and enhance cybersecurity resilience. For more information on SBOM, visit: https://www.cisa.gov/sbom. For leadership statements from co-authoring organizations, visit: Statements of Support on A Shared Vision of SBOM for Cybersecurity.

CISA and Partners Release Joint Advisory on Countering Chinese State-Sponsored Actors Compromise of Networks Worldwide to Feed Global Espionage Systems
Aug 27, 2025
CISA, along with the National Security Agency, Federal Bureau of Investigation, and international partners, released a joint Cybersecurity Advisory on People’s Republic of China (PRC) state-sponsored Advanced Persistent Threat (APT) actors targeting critical infrastructure across sectors and continents to maintain persistent, long-term access to networks. This advisory builds on previous reporting and is based on real-world investigations conducted across multiple countries through July 2025. While the activity observed overlaps with industry reporting on the group known as Salt Typhoon, OPERATOR PANDA, RedMike, UNC5807, and GhostEmperor, among others, the advisory refers to them generically as APT actors to focus on the behavior, not the alias. These APT actors are exploiting vulnerabilities in the large backbone routers of telecommunications providers—specifically provider edge and customer edge routers that often lack visibility and are difficult to monitor—to gain and maintain persistent access, particularly in telecommunications, government, transportation, lodging, and defense networks. They often modify router firmware and configurations to evade detection and establish long-term footholds. CISA and authoring partners strongly urge network defenders, particularly those in high-risk sectors, to hunt for malicious activity and implement the mitigations outlined in this advisory. For more detailed information, review the full advisory and CISA’s People’s Republic of China Cyber Threat Overview and Advisories web page.
