CISA Adds Three Known Exploited Vulnerabilities to Catalog
Sep 3, 2024
CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2021-20123 Draytek VigorConnect Path Traversal Vulnerability CVE-2021-20124 Draytek VigorConnect Path Traversal Vulnerability CVE-2024-7262 Kingsoft WPS Office Path Traversal 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.

CISA and Partners Release Advisory on RansomHub Ransomware
Aug 29, 2024
Today, CISA—in partnership with the Federal Bureau of Investigation (FBI), Multi-State Information Sharing and Analysis Center (MS-ISAC), and Department of Health and Human Services (HHS)—released a joint Cybersecurity Advisory, #StopRansomware: RansomHub Ransomware. This advisory provides network defenders with indicators of compromise (IOCs), tactics, techniques, and procedures (TTPs), and detection methods associated with RansomHub activity identified through FBI investigations and third-party reporting as recently as August 2024. RansomHub is a ransomware-as-a-service variant—formerly known as Cyclops and Knight—which has recently attracted high-profile affiliates from other prominent variants such as LockBit and ALPHV. CISA encourages network defenders to review this advisory and apply the recommended mitigations. See #StopRansomware and the #StopRansomware Guide for additional guidance on ransomware protection, detection, and response. Visit CISA’s Cross-Sector Cybersecurity Performance Goals for more information on the CPGs, including added recommended baseline protections. CISA encourages software manufacturers to take ownership of improving the security outcomes of their customers by applying secure by design methods. For more information on Secure by Design, see CISA’s Secure by Design webpage and joint guide Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software.

CISA and Partners Release Advisory on Iran-based Cyber Actors Enabling Ransomware Attacks on US Organizations
Aug 28, 2024
Today, CISA—in partnership with the Federal Bureau of Investigation (FBI) and the Department of Defense Cyber Crime Center (DC3)—released Iran-based Cyber Actors Enabling Ransomware Attacks on U.S. Organizations. This joint advisory warns of cyber actors, known in the private sector as Pioneer Kitten, UNC757, Parisite, Rubidium, and Lemon Sandstorm, targeting and exploiting U.S. and foreign organizations across multiple sectors in the U.S. FBI investigations conducted as recently as August 2024 assess that cyber actors like Pioneer Kitten are connected with the Government of Iran (GOI) and linked to an Iranian information technology (IT) company. Their malicious cyber operations are aimed at deploying ransomware attacks to obtain and develop network access. These operations aid malicious cyber actors in further collaborating with affiliate actors to continue deploying ransomware. This advisory highlights similarities to a previous advisory, Iran-Based Threat Actor Exploits VPN Vulnerabilities published on Sept. 15, 2020, and provides known indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs). CISA and partners encourage critical infrastructure organizations to review and implement the mitigations provided in this joint advisory to reduce the likelihood and impact of ransomware incidents. For more information on Iranian state-sponsored threat actor activity, see CISA’s Iran Cyber Threat Overview and Advisories page. See #StopRansomware along with the updated #StopRansomware Guide for additional guidance on ransomware protection, detection, and response. Visit CISA’s Cross-Sector Cybersecurity Performance Goals for more information on the CPGs, including additional recommended baseline protections.
