CISA and Partners Release Joint Guidance on PRC-Affiliated Threat Actor Compromising Networks of Global Telecommunications Providers
Dec 3, 2024
Today, CISA—in partnership with the National Security Agency (NSA), the Federal Bureau of Investigation (FBI), and international partners—released joint guidance, Enhanced Visibility and Hardening Guidance for Communications Infrastructure. Partners of this guidance include: Australian Signals Directorate’s (ASD’s) Australian Cyber Security Centre (ACSC) Canadian Centre for Cyber Security (CCCS) New Zealand’s National Cyber Security Centre (NCSC-NZ) This guidance was crafted in response to a People’s Republic of China (PRC)-affiliated threat actor’s compromise of "networks of major global telecommunications providers to conduct a broad and significant cyber espionage campaign." The compromise of private communications impacted a limited number of individuals who are primarily involved in government or political activity. CISA and partners encourage network defenders and engineers of communications infrastructure, and other critical infrastructure organizations with on-premises enterprise equipment, to review and apply the provided best practices, including patching vulnerable devices and services, to reduce opportunities for intrusion. For more information on PRC state-sponsored threat actor activity, see CISA’s People's Republic of China Cyber Threat. For more information on secure by design principles, see CISA’s Secure by Design webpage. Customers should refer to CISA’s Secure by Demand guidance for additional product security considerations.

2024 CWE Top 25 Most Dangerous Software Weaknesses
Nov 20, 2024
The Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with the Homeland Security Systems Engineering and Development Institute (HSSEDI), operated by MITRE, has released the 2024 CWE Top 25 Most Dangerous Software Weaknesses. This annual list identifies the most critical software weaknesses that adversaries frequently exploit to compromise systems, steal sensitive data, or disrupt essential services.Organizations are strongly encouraged to review this list and use it to inform their software security strategies. Prioritizing these weaknesses in development and procurement processes helps prevent vulnerabilities at the core of the software lifecycle. Addressing these weaknesses is integral to CISA’s Secure by Design and Secure by Demand initiatives, which advocate for building and procuring secure technology solutions: Secure by Design: Encourages software manufacturers to implement security best practices throughout the design and development phases. By proactively addressing common weaknesses found in the CWE Top 25, manufacturers can deliver inherently secure products that reduce risk to end users. Learn more about Secure by Design here. Secure by Demand: Provides guidelines for organizations to drive security improvements when procuring software. Leveraging the CWE Top 25, customers can establish security expectations and ensure that their software vendors are committed to mitigating high-risk weaknesses from the outset. Explore how you can integrate Secure by Demand principles here. Recommendations for Stakeholders: For Developers and Product Teams: Review the 2024 CWE Top 25 to identify high-priority weaknesses and adopt Secure by Design practices in your development processes. For Security Teams: Incorporate the CWE Top 25 into your vulnerability management and application security testing practices to assess and mitigate the most critical weaknesses. For Procurement and Risk Managers: Use the CWE Top 25 as a benchmark when evaluating vendors, and apply Secure by Demand guidelines to ensure that your organization is investing in secure products. By following CISA’s initiatives, organizations can reduce vulnerabilities and strengthen application and infrastructure security. Incorporating the 2024 CWE Top 25 into cybersecurity and procurement strategies will enhance overall resilience. For further details, refer to the full 2024 CWE Top 25 list here.

CISA and Partners Release Update to BianLian Ransomware Cybersecurity Advisory
Nov 20, 2024
Today, CISA, the Federal Bureau of Investigation (FBI), and the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) released updates to #StopRansomware: BianLian Ransomware Group on observed tactics, techniques, and procedures (TTPs) and indicators of compromise attributed to data extortion group, BianLian. The advisory, originally published May 2023, has been updated with additional TTPs obtained through FBI and ASD’s ACSC investigations and industry threat intelligence as of June 2024. BianLian is likely based in Russia, with Russia-based affiliates, and has affected organizations in multiple U.S. critical infrastructure sectors since June 2022. They have also targeted Australian critical infrastructure sectors, professional services, and property development. CISA and partners encourage infrastructure organizations and small- to medium-sized organizations implement mitigations in this advisory to reduce the likelihood and impact of BianLian and other ransomware incidents. These mitigations align with the Cross-Sector Cybersecurity Performance Goals developed by CISA and the National Institute of Standards and Technology.

USDA Releases Success Story Detailing the Implementation of Phishing-Resistant Multi-Factor Authentication
Nov 20, 2024
Today, the Cybersecurity and Infrastructure Security Agency (CISA) and the U.S. Department of Agriculture (USDA) released Phishing-Resistant Multi-Factor Authentication (MFA) Success Story: USDA’s FIDO Implementation. This report details how USDA successfully implemented phishing-resistant authentication for its personnel in situations where USDA could not exclusively rely on personal identity verification (PIV) cards. USDA turned to Fast IDentity Online (FIDO) capabilities, a set of authentication protocols that uses cryptographic keys on user devices, to offer a secure way to authenticate user identities without passwords. USDA’s adoption of FIDO highlights the importance of organizations moving away from password authentication and adopting more secure MFA technologies. This report offers examples to help organizations strengthen their cybersecurity posture through use cases, recommended actions, and resources. USDA successfully implemented MFA by adopting a centralized model, making incremental improvements, and addressing specific use cases. Organizations facing challenges with phishing-resistant authentication are encouraged to review this report. For more information about phishing-resistant MFA, visit Phishing-Resistant MFA is Key to Peace of Mind and Implementing Phishing-Resistant MFA.
