CISA Adds One Known Exploited Vulnerability to Catalog
May 1, 2024
CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2023-7028 GitLab Community and Enterprise Editions Improper Access Control 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 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 and Partners Release Fact Sheet on Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity
May 1, 2024
Today, CISA, in collaboration with U.S. and international partners, published a joint fact sheet, Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity. This fact sheet provides information and mitigations associated with cyber operations conducted by pro-Russia hacktivists who seek to compromise industrial control systems (ICS) and small-scale operational technology (OT) systems in North American and European critical infrastructure sectors, including Water and Wastewater Systems, Dams, Energy, and Food and Agriculture Sectors. The pro-Russia hacktivist activity appears mostly limited to unsophisticated techniques that manipulate ICS equipment to create nuisance effects. However, investigations have identified that these actors are capable of techniques that pose physical threats against insecure and misconfigured OT environments. CISA and partners encourage OT operators in critical infrastructure sectors to apply the recommendations listed in the fact sheet to defend against this activity. To learn more about secure by design principles and practices, visit CISA's Secure by Design webpage. For more information and guidance on protection against the most common and impactful threats, tactics, techniques, and procedures, visit CISA’s Cross-Sector Cybersecurity Performance Goals.

CISA and Partners Release Advisory on Akira Ransomware
Apr 18, 2024
Today, CISA, the Federal Bureau of Investigation (FBI), Europol’s European Cybercrime Centre (EC3), and the Netherlands’ National Cyber Security Centre (NCSC-NL) released a joint Cybersecurity Advisory (CSA), #StopRansomware: Akira Ransomware, to disseminate known Akira ransomware tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) identified through FBI investigations as recently as February 2024. Evolving from an initial focus on Windows systems to a Linux variant targeting VMware ESXi virtual machines, Akira threat actors began deploying Megazord (a Rust-based code) and Akira (written in C++), including Akira_v2 (also Rust-based) in August 2023. Akira ransomware has impacted a wide range of businesses and critical infrastructure entities in North America, Europe, and Australia and claimed approximately $42 million (USD) in ransomware proceeds. CISA and partners encourage critical infrastructure organizations to review and implement the mitigations provided in the joint CSA to reduce the likelihood and impact of Akira and other ransomware incidents.
