Today, the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) released an updated version of the joint #StopRansomware Guide. The update includes new prevention tips such as hardening SMB protocols, revised response steps, and added threat hunting insights. Developed through the U.S. Joint Ransomware Task Force (JRTF), #StopRansomware Guide is designed to be a one-stop resource to help organizations minimize the risks posed by ransomware incidents through best practices to detect, prevent, respond, and recover, including step-by-step approaches to address potential attacks. CISA and its partners encourage organizations to implement the recommendations in the guide to reduce the likelihood and impact of ransomware incidents. For more information, visit CISA’s Stop Ransomware page.

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2023-4966 Citrix NetScaler ADC and NetScaler Gateway Buffer Overflow Vulnerability CVE-2021-1435 Cisco IOS XE Web UI Command Injection Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other newly added vulnerabilities in the catalog, click on the arrow in the "Date Added to Catalog" column—which will sort by descending dates. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
