CISA Marks Important Milestone in Addressing Cyber Incidents; Seeks Input on CIRCIA Notice of Proposed Rulemaking
March 27, 2024

The Federal Register posted for public inspection the Department of Homeland Security’s (DHS) Cybersecurity and Infrastructure Security Agency (CISA); Notice of Proposed Rulemaking (NPRM), which CISA was required to develop by the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA). This marks a major step in bolstering America’s cybersecurity. 

Implementation of CIRCIA will improve CISA’s ability to use cybersecurity incident and ransomware payment information reported to the agency to identify patterns in real-time, fill critical information gaps, rapidly deploy resources to help entities that are suffering from cyber attacks, and inform others who would be potentially affected. When information about cyber incidents is shared quickly, CISA can use this information to render assistance and provide warning to prevent other organizations from falling victim to a similar incident. This information is also critical to identifying trends that can help efforts to protect the homeland. The NPRM will soon formally publish in the Federal Register, following which the public will have 60 days to submit written comments to inform the direction and substance of the Final Rule.

“Cyber incident reports submitted to us through CIRCIA will enable us to better protect our nation’s critical infrastructure,” said Secretary of Homeland Security Alejandro N. Mayorkas.  “CIRCIA enhances our ability to spot trends, render assistance to victims of cyber incidents, and quickly share information with other potential victims, driving cyber risk reduction across all critical infrastructure sectors. The proposed rule is the result of collaboration with public and private stakeholders, and DHS welcomes feedback during the public comment period on the direction and substance of the final rule.”


03/12/2024 

CISA has published Secure Cloud Business Applications (SCuBA) Hybrid Identity Solutions Guidance (HISG) to help users better understand identity management capabilities and securely integrate their traditional on-premises enterprise networks with cloud-based solutions.

01/30/2024 

Note: CISA will update this Alert with more information as it becomes available.

Updated Jan. 31, 2024:

CISA urges organizations to follow the updated guidance—including software updates—that Ivanti has published to their KB article, which includes:

  • Two additional vulnerabilities in all supported versions (9.x and 22.x) of Ivanti Connect Secure and Policy Secure Gateways:
  • A cyber threat actor could exploit CVE-2024-21888 and CVE-2024-21893 to take control of an affected system. Ivanti’s KB article includes software updates that cover these vulnerabilities in specific versions of the software as well as mitigations for affected software versions that do not yet have updates.
  • Software updates are also available for the previously reported Ivanti Connect Secure and Policy Secure Gateways vulnerabilities in Ivanti devices (CVE-2023-46805 and CVE-2024-21887). Note: See the KB article for the specific versions that these updates apply to as well as specific guidance on implementing the updates. Ivanti will publish additional information and software updates to the KB article as these become available.

Additionally, CISA has issued a Supplemental Direction to its Emergency Directive on Ivanti Vulnerabilities. Although the Supplemental Direction and Emergency Directive are only for FCEB agencies, CISA strongly encourages all organizations to review the guidance and implement it as applicable.

End of Jan. 31 update

CISA is releasing this alert to provide cyber defenders with new mitigations to defend against threat actors exploiting Ivanti Connect Secure and Policy Secure Gateways vulnerabilities in Ivanti devices (CVE-2023-46805 and CVE-2024-21887).

Threat actors are continuing to leverage vulnerabilities in Ivanti Connect Secure and Policy Secure Gateways to capture credentials and/or drop webshells that enable further compromise of enterprise networks. Some threat actors have recently developed workarounds to current mitigations and detection methods and have been able to exploit weaknesses, move laterally, and escalate privileges without detection. CISA is aware of instances in which sophisticated threat actors have subverted the external integrity checker tool (ICT), further minimizing traces of their intrusion.

If an organization has been running Ivanti Connect Secure (9.x and 22.x) and Policy Secure gateways over the last several weeks and/or continues to run these products, CISA recommends continuous threat hunting on any systems connected to—or recently connected to—the Ivanti device. Additionally, organizations should monitor authentication, account usage, and identity management services that could be exposed and isolate the system(s) from any enterprise resources as much as possible.

After applying patches, when these become available, CISA recommends that organizations continue to hunt their network in order to detect any compromise that may have occurred before patches were implemented.

This guidance supplements CISA’s previous guidance for mitigation and detection, which remains applicable. For previous guidance, see CISA Issues Emergency Directive on Ivanti Vulnerabilities and Ivanti Releases Security Update for Connect Secure and Policy Secure Gateways.


01/26/2024 

Today, CISA published Guidance on Assembling a Group of Products created by the Software Bill of Materials (SBOM) Tooling & Implementation Working Group, one of the five SBOM community-driven workstreams facilitated by CISA. CISA’s community-driven working groups publish documents and reports to advance and refine SBOM and ultimately promote adoption. Specifically, software producers often need to assemble and test products together before releasing them to customers. These products may contain components that experience version changes over time, therefore creating a need to be tracked. This document serves as a guide for creating the build for SBOM assembled products.

Specifically, these vulnerabilities allow the actor to create a privileged account that provides complete control over the device.

CISA urges organizations running Cisco IOS XE Web UI to review CISA’s guidance and immediately implement the mitigations outlined in:

These mitigations include disabling the HTTP Server feature on internet-facing systems, and hunt for malicious activity on their network.


CISA Releases New Resources Identifying Known Exploited Vulnerabilities and Misconfigurations Linked to Ransomware
Oct. 12, 2023

Today, as part of the Ransomware Vulnerability Warning Pilot (RVWP), CISA launched two new resources for combating ransomware campaigns:

  • A “Known to be Used in Ransomware Campaigns” column in the KEV Catalog that identifies KEVs associated with ransomware campaigns.
  • A “Misconfigurations and Weaknesses Known to be Used in Ransomware Campaigns” table on StopRansomware.gov that identifies misconfigurations and weaknesses associated with ransomware campaigns. The table features a column that identifies the Cyber Performance Goal (CPG) action for each misconfiguration or weakness.

These two new resources will help organizations become more cybersecure by providing mitigations that protect against specific KEVs, misconfigurations, and weaknesses associated with ransomware.

CISA encourages all organizations to review the blog about this RVWP effort, as well as the new KEV catalog column and updated StopRansomware.gov site and implement applicable mitigations today.

Today, the Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory (CSA), Identification and Disruption of QakBot Infrastructure, to help organizations detect and protect against newly identified QakBot-related activity and malware. QakBot—also known as Qbot, Quackbot, Pinkslipbot, and TA570—is responsible for thousands of malware infections globally.

Originally used as a banking trojan to steal banking credentials for account compromise, QakBot—in most cases—was delivered via phishing campaigns containing malicious attachments or links to download the malware, which would reside in memory once on the victim network. QakBot has since grown to deploy multiple types of malware, trojans, and highly-destructive ransomware variants targeting the United States and other global infrastructures, including the Election Infrastructure Subsector, Financial Services, Emergency Services, and Commercial Facilities Sectors.

CISA and FBI urge organizations to implement the recommendations contained within the joint CSA to reduce the likelihood of QakBot-related activity and promote identification of QakBot-facilitated ransomware and malware infections. To report incidents and anomalous activity, please contact one of the following organizations:

Organizations are also encouraged to visit CISA‘s Malware, Phishing, and Ransomware and StopRansomware.gov pages—StopRansomware provides a range of free U.S. government resources and services that can help bolster cyber hygiene, cybersecurity posture and reduce risk to ransomware, and contains an updated Joint #StopRansomware Guide.
