CISA and Partners Urge Critical Infrastructure to Stay Vigilant in the Current Geopolitical Environment
Jun 30, 2025
Today, CISA, in collaboration with the Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center (DC3), and the National Security Agency (NSA), released a Fact Sheet urging organizations to remain vigilant against potential targeted cyber operations by Iranian state-sponsored or affiliated threat actors. Over the past several months, there has been increasing activity from hacktivists and Iranian government-affiliated actors, which is expected to escalate due to recent events. These cyber actors often exploit targets of opportunity based on the use of unpatched or outdated software with known Common Vulnerabilities and Exposures or the use of default or common passwords on internet-connected accounts and devices. At this time, we have not seen indications of a coordinated campaign of malicious cyber activity in the U.S. that can be attributed to Iran. However, CISA, FBI, DC3, and NSA strongly urge critical infrastructure asset owners and operators to implement the mitigations recommended in the joint Fact Sheet, which include: Identifying and disconnecting operational technology and industrial control systems devices from the public internet, Protecting devices and accounts with strong, unique passwords, Applying the latest software patches, and Implementing phishing-resistant multifactor authentication for access to OT networks. Review the joint Fact Sheet: Iranian Cyber Actors May Target Vulnerable US Networks and Entities of Interest and act now to understand the Iranian state-backed cyber threat, assess and mitigate cybersecurity weaknesses, and review and update incident response plans to strengthen your network against malicious cyber actors.

New Guidance Released for Reducing Memory-Related Vulnerabilities
Jun 24, 2025
Today, CISA, in partnership with the National Security Agency (NSA), released a joint guide on reducing memory-related vulnerabilities in modern software development. Memory safety vulnerabilities pose serious risks to national security and critical infrastructure. Adopting memory safe languages (MSLs) offers the most comprehensive mitigation against this class of vulnerabilities and provides built-in safeguards that enhance security by design. CISA’s Secure by Design program advocates for integrating proactive security measures throughout the software development lifecycle, with MSLs as a central component. Consistent support for MSLs underscores their benefits for national security and resilience by reducing exploitable flaws before products reach users. This joint guide outlines key challenges to adopting MSLs, offers practical approaches for overcoming them, and highlights important considerations for organizations seeking to transition toward more secure software development practices. Organizations in academia, U.S. government, and private industry are encouraged to review this guidance and support adoption of MSLs. In addition to the product published today, CISA and the NSA previously released the joint guide, The Case for Memory Safe Roadmaps. To learn more about memory safety, visit Secure by Design on CISA.gov. Please share your thoughts with us via our anonymous product survey; we welcome your feedback.
