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 These cyber actors often exploit targets of opportunity based on the use of unpatched or outdated software with known Common Vulnerabilities and Exposures or the use of default or common passwords on internet-connected accounts and devices.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. 

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.   CVE-2025-6543 Citrix NetScaler ADC and Gateway Buffer Overflow Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.  Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise.
