A joint Cybersecurity Advisory highlights Iran-based cyber actor ransomware activity targeting U.S. organizations. The advisory includes CVEs exploited, alongside techniques, tactics and procedures used by the threat actors.

Background

On August 28, the Cybersecurity and Infrastructure Security Agency (CISA) published a joint Cybersecurity advisory (CSA) in coordination with The Federal Bureau of Investigation (FBI) and the Department of Defense Cyber Crime Center (DC3). The advisory highlights the recent activities of Iranian threat actors conducting ransomware operations against US organizations across several industries including local government, defense, finance, education and healthcare as well as other countries including Israel, Azerbaijan and the United Arab Emirates.

The threat actors named in the advisory go by a few monikers including Pioneer Kitten, Fox Kitten, UNC757, Parasite, RUBIDIUM and Lemon Sandstorm. These actors have been observed to be collaborating with ransomware groups including NoEscape, Ransomhouse and ALPHV (aka BlackCat) to extort their victims. The technical aspects of the advisory highlight what techniques, tactics and procedures (TTPs) the threat actors have been observed using, including indicators of compromise (IOCs). The advisory flags six specific CVEs that are leveraged by the threat actors in the initial access phase of their attacks:

Analysis

CVE-2024-3400 is a remote code execution vulnerability that arises from a combination of two distinct bugs in PAN-OS, specifically affecting the GlobalProtect service. The first bug is related to how the GlobalProtect service handles session IDs. The service did not sufficiently validate the format of session IDs before storing them. This oversight allowed an attacker to store an empty file with a filename of their choosing, effectively setting the stage for the exploit. The second bug involves the assumption that filenames used within the system were system-generated and therefore trustworthy. This bug enabled the filenames, which were injected by the attacker in the first step, to be used as part of a command. An attacker can exploit these two bugs to execute remote shell commands without any prior authentication. Earlier this year, this vulnerability was exploited in-the-wild as a zero-day vulnerability and was tracked at the time by Palo Alto Networks Unit 42, calling the activity Operation MidnightEclipse.

CVE-2024-24919 is an information disclosure vulnerability affecting CheckPoint Security Gateway devices configured with either the remote Access VPN or Mobile Access Software Blades enabled. This vulnerability allows an unauthenticated remote attacker to read the contents of arbitrary files located on the affected appliance. This could allow an attacker to read sensitive files. An example of one such attack path is accessing the ‘/etc/shadow’ file, which could result in the extraction of password hashes for local accounts that could potentially be decrypted. This vulnerability was also exploited in-the-wild as a zero-day, around the same time security researchers also published a proof-of-concept (PoC).

CVE-2019-19781 is a directory traversal vulnerability in Citrix Application Delivery Controller (ADC) and Gateway, formerly known as NetScaler ADC and Netscaler Gateway. This vulnerability allows an attacker to send a specially crafted HTTP request that exploits the path traversal issue, enabling unauthorized access to restricted directories on the device. Through this access, the attacker can execute arbitrary code without any need for authentication, potentially resulting in remote code execution (RCE) on the affected device. This vulnerability has been widely abused by multiple threat actors over the years and has been featured prominently in our 2020, 2021 and 2022 Threat Landscape Reports. Additionally, it has been featured in multiple blogs from Tenable Research and has been included in multiple CSA’s from CISA and other government entities across the globe.

CVE-2023-3519 is a critical RCE vulnerability in Citrix ADC and Citrix Gateway that allows an unauthenticated attacker to execute arbitrary code on the vulnerable appliances. The attack can be performed over the network, making it particularly dangerous in environments where these devices are exposed to the internet. The vulnerability stems from improper handling of specific request data, leading to memory corruption that can be exploited to gain control of the system.

CVE-2022-1388 is an iControl REST RCE vulnerability in F5 BIG-IP devices stemming from an authentication bypass bug. The flaw resides in the iControl REST interface, where improper access control allows unauthenticated users to execute arbitrary system commands with root privileges. This vulnerability is particularly dangerous because it does not require user interaction or authentication, making it easy for attackers to exploit. Successful exploitation of CVE-2022-1388 can lead to complete system compromise, enabling attackers to take full control of the device, modify configurations, exfiltrate sensitive data and use the compromised device as a launching point for further attacks within the network.

CVE-2024-21887 is a command injection vulnerability in Ivanti Connect Secure and Ivanti Policy Secure that allows remote attackers to execute arbitrary commands on the affected devices. This vulnerability occurs due to insufficient input validation in the administrative interface, which can be exploited by sending specially crafted HTTP requests. Successful exploitation can result in full system compromise, providing the attacker with the ability to execute commands with the highest privileges, potentially leading to data loss, system disruption or further propagation of malicious activity.

Legacy Vulnerabilities Remain a Looming Threat

An analysis of metadata performed by Tenable Research provides us with unique insight to two of these legacy CVEs, CVE-2019-19781 and CVE-2022-1388. From our research only about half of impacted assets have been successfully remediated. Legacy vulnerabilities present a significant risk, as threat actors frequently exploit unpatched vulnerabilities, particularly in SSL VPNs. This trend has been consistently highlighted by the Tenable Security Response Team (SRT) in their annual Threat Landscape Reports as mentioned in the section for CVE-2019-19781. To mitigate these risks, it is imperative to prioritize the remediation of legacy vulnerabilities alongside newer threats, ensuring a more comprehensive and robust security posture.

DSPM solutions provide a comprehensive, up-to-date view into cloud-based data and risk. An integrated CNAPP and DSPM solution elevates this analysis to expose toxic combinations and security gaps across cloud environments.

As organizations ramp up their use of cloud-native applications, the amount of sensitive data stored in the cloud grows – as does the difficulty in managing and scaling data-related risk management and compliance. Hackers are motivated to get at data stored in the cloud. Employee data, customer information, business IP – it’s all (un)fair game. 

Enter cloud native application protection (CNAPP) solutions. In light of the massive increase in data-related breaches - and their cost, integrating data security posture management (DSPM) in CNAPP is essential to reduce risk. It also simplifies security efforts, improves compliance and ensures that data security is an integral part of your overall security strategy.

See the demo

The superpower of a unified CNAPP

A quick concept review.

A CNAPP offers security and compliance for cloud-native applications throughout their lifecycle, across multiple clouds. Its superpower lies in providing a unified view and contextual analysis across infrastructure, workloads, identities and more. A CNAPP isolates exposures, including hidden toxic combinations, and pinpoints how to fix them. 

DSPM tools – a $94 billion market projected to double by 2031(InsightScan) – focus specifically on security and compliance-readiness for data in the cloud. These tools continuously scan the environment to find data, including databases, object storage and data lakes, across cloud and service providers, flowing to or from, any location. They classify and protect data assets, ensure audit security policies and requirements, and detect data-related threats. 

Using DSPM alone makes it difficult to maintain a centralized and deep view into sensitive data; where it’s stored, what kind it is, who can access it and how it is used. It’s like getting a view into the stars but not the galaxy. Inside a CNAPP, DSPM gives the needed illumination and context.

Let’s explore how a DSPM works.

Comprehensive visibility into data assets

A key DSPM function is to continuously provide a comprehensive, up-to-date view into cloud based data assets and risk. When joined with cloud security posture, this data analysis exposes discreet security gaps and toxic combinations and, importantly, the impact on data if exploited. Teams gain greater prioritization accuracy and focus around findings, mitigating alert fatigue. 

Figure - Integrated DSPM in a CNAPP enables powerful permission queries into specific types of sensitive data, such as digital identities, for prioritized focus on risk exposure Better data security and compliance 

By implementing a DSPM-integrated CNAPP, you can reduce the risk of data breaches and non-compliance. DSPM solutions continuously assess compliance posture and ensure that cloud data is classified, protected and accessed according to policies and frameworks such as GDPR, HIPAA, and CCPA. You can automate policy enforcement and generate comprehensive, audit-ready reports to reduce compliance fire drills. Users can act quickly upon discovering misconfigurations, unauthorized access and potential security threats discovered in near real-time.

Managing data risk proactively 

Proactive risk management is a cornerstone of cloud security. Integrating DSPM empowers teams to detect potential data risks, as well, and take action early, before they become big problems. Through the use of advanced analytics, DSPM capabilities detect anomalous patterns and behaviors that can indicate a security threat to your sensitive data. A DSPM integrated CNAPP provides actionable insights and recommendations for improving your overall data security posture, ensuring your organization stays a step ahead of evolving threats.

Faster, streamlined incident response

In the event of a security incident, time and action is everything. Integrated DSPM plays a vital role in streamlining the incident response process. By providing near real-time alerts and detailed forensic data, the solution helps security teams quickly identify the scope and impact of a breach. These insights speed up the process, enabling stakeholders to achieve containment and remediation and minimize potential damage. DSPM's integration with other CNAPP components, such as workload protection and cloud security posture management, enables a coordinated, efficient incident response, reducing downtime and maintaining business continuity. 

Use case: Tenable Cloud Security with integrated DSPM

Tenable Cloud Security isolates and eradicates cloud risks across infrastructure, workloads, identities and data. Having recently acquired Eureka Security, we are now integrating leading DSPM capabilities into our CNAPP context mix - stay tuned as new features roll out.

In this use case, we show how you can use powerful permission querying to detect and filter for resources with certain types of sensitive data, such as digital identity or financial information, to understand and explore your risk exposure, and focus on prioritized security findings. 

Conclusion

Integrated DSPM is an indispensable component of a robust CNAPP strategy. It extends comprehensive visibility and deep risk context to data assets, safeguarding data and keeping your security posture strong through automation and actionability.

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.

Researchers have created orange, yellow and green lasers tiny enough to fit on a chip.

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.
