CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CVE-2024-38189 Microsoft Project Remote Code Execution Vulnerability CVE-2024-38178 Microsoft Windows Scripting Engine Memory Corruption Vulnerability CVE-2024-38213 Microsoft Windows SmartScreen Security Feature Bypass Vulnerability CVE-2024-38193 Microsoft Windows Ancillary Function Driver for WinSock Privilege Escalation Vulnerability CVE-2024-38106 Microsoft Windows Kernel Privilege Escalation Vulnerability CVE-2024-38107 Microsoft Windows Power Dependency Coordinator Privilege Escalation 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 will continue to add vulnerabilities to the catalog that meet the specified criteria.

Overview Background

This advisory, authored by the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), the United States Cybersecurity and Infrastructure Security Agency (CISA), the United States National Security Agency (NSA), the United States Federal Bureau of Investigation (FBI), the United Kingdom National Cyber Security Centre (NCSC-UK), the Canadian Centre for Cyber Security (CCCS), the New Zealand National Cyber Security Centre (NCSC-NZ), the German Federal Intelligence Service (BND) and Federal Office for the Protection of the Constitution (BfV), the Republic of Korea’s National Intelligence Service (NIS) and NIS’ National Cyber Security Center, and Japan’s National Center of Incident Readiness and Strategy for Cybersecurity (NISC) and National Police Agency (NPA)—hereafter referred to as the “authoring agencies”—outlines a People’s Republic of China (PRC) state-sponsored cyber group and their current threat to Australian networks. The advisory draws on the authoring agencies’ shared understanding of the threat as well as ASD’s ACSC incident response investigations.

The PRC state-sponsored cyber group has previously targeted organizations in various countries, including Australia and the United States, and the techniques highlighted below are regularly used by other PRC state-sponsored actors globally. Therefore, the authoring agencies believe the group, and similar techniques remain a threat to their countries’ networks as well.

The authoring agencies assess that this group conduct malicious cyber operations for the PRC Ministry of State Security (MSS).

SUMMARY

Note: This joint Cybersecurity Advisory (CSA) is part of an ongoing #StopRansomware effort to publish advisories for network defenders that detail various ransomware variants and ransomware threat actors. These #StopRansomware advisories include recently and historically observed tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) to help organizations protect against ransomware. Visit stopransomware.gov to see all #StopRansomware advisories and to learn more about other ransomware threats and no-cost resources.

The Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), Department of Health and Human Services (HHS), and Multi-State Information Sharing and Analysis Center (MS-ISAC) (hereafter referred to as the authoring organizations) are releasing this joint CSA to provide information on Black Basta, a ransomware variant whose actors have encrypted and stolen data from at least 12 out of 16 critical infrastructure sectors, including the Healthcare and Public Health (HPH) Sector.

This joint CSA provides TTPs and IOCs obtained from FBI investigations and third-party reporting. Black Basta is considered a ransomware-as-a-service (RaaS) variant and was first identified in April 2022. Black Basta affiliates have impacted a wide range of businesses and critical infrastructure in North America, Europe, and Australia. As of May 2024, Black Basta affiliates have impacted over 500 organizations globally.

Black Basta affiliates use common initial access techniques—such as phishing and exploiting known vulnerabilities—and then employ a double-extortion model, both
