CISA News

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 released three Industrial Control Systems (ICS) advisories on August 29, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

• ICSA-24-242-01 Rockwell Automation ThinManager ThinServer
• ICSA-24-242-02 Delta Electronics DTN Soft
   
• ICSA-24-226-06 Rockwell Automation FactoryTalk View Site Edition (Update A)

CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations.

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

• CVE-2024-7965 Google Chromium V8 Inappropriate Implementation 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.

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.

Today, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), CISA, FBI, NSA, and international partners are releasing Best Practices for Event Logging and Threat Detection. This guide will assist organizations in defining a baseline for event logging to mitigate malicious cyber threats.

The increased prevalence of malicious actors employing living off the land (LOTL) techniques, such as living off the land binaries (LOLBins) and fileless malware, highlights the importance of implementing and maintaining an effective event logging program.

 CISA encourages public and private sector senior information technology (IT) decision makers, operational technology (OT) operators, network administrators, network operators, and critical infrastructure organizations to review the best practices in the guide and implement recommended actions. These actions can help detect malicious activity, behavioral anomalies, and compromised networks, devices, or accounts.

For more information on LOTL techniques, see joint guidance Identifying and Mitigating Living Off the Land Techniques and CISA’s Secure by Design Alert Series.

For more information and guidance on event logging and threat detection, see CISA’s Secure Cloud Business Applications (SCuBA) products, network traffic analysis tool Malcom, and Logging Made Easy.
