Clop Claims Zero-Day Attacks Against 130 Organizations

Russia-linked ransomware gang Clop has claimed that it has attacked over 130 organizations since late January, using a zero-day vulnerability in the GoAnywhere MFT secure file transfer tool, and was successful in stealing data from those organizations. The vulnerability is CVE-2023-0669, which allows attackers to execute remote code execution.

The manufacturer of GoAnywhere MFT notified customers of the vulnerability on February 1, 2023, and issued a patch for the vulnerability on February 7, 2023.

HC3 issued an alert on February 22, 2023, warning the health care sector about Clop targeting healthcare organizations and recommended:

Educate and train staff to reduce the risk of social engineering attacks via email and network access.
Assess enterprise risk against all potential vulnerabilities and prioritize implementing the security plan with the necessary budget, staff, and tools.
Develop a cybersecurity roadmap that everyone in the healthcare organization understands.

Security professionals are recommending that information technology professionals update machines to the latest GoAnywhere version and “stop exposing port 8000 (the internet location of the GoAnywhere MFT admin panel).”

Privacy Tip #358 – Bank Failures Give Hackers New Strategy for Attacks

Hackers are always looking for the next opportunity to launch attacks against unsuspecting victims. According to Cybersecurity Dive, researchers at Proofpoint recently observed “a phishing campaign designed to exploit the banking crisis with messages impersonating several cryptocurrencies.”

According to Cybersecurity Dive, cybersecurity firm Arctic Wolf has observed “an uptick in newly registered domains related to SVB since federal regulators took over the bank’s deposits…” and “expects some of those domains to serve as a hub for phishing attacks.”

This is the modus operandi of hackers. They use times of crises, when victims are vulnerable, to launch attacks. Phishing campaigns continue to be one of the top risks to organizations, and following the recent bank failures, everyone should be extra vigilant of urgent financial requests and emails spoofing financial institutions, and take additional measures, through multiple levels of authorization, when conducting financial transactions.

We anticipate increased activity following these recent financial failures attacking individuals and organizations. Communicating the increased risk to employees may be worth consideration.

Another Lesson for Higher Education Institutions about the Importance of Cybersecurity Investment

Key Takeaway

A Massachusetts class action claim underscores that institutions of higher education will continue to be targets for cybercriminals – and class action plaintiffs know it.

Background

On January 4, 2023, in Jackson v. Suffolk University, No. 23-cv-10019, Jackson (Plaintiff) filed a proposed class action lawsuit in the U.S. District Court for the District of Massachusetts against her alma matter, Suffolk University (Suffolk), arising from a data breach affecting thousands of current and former Suffolk students.

The complaint alleges that an unauthorized party gained access to Suffolk’s computer network on or about July 9, 2022. After learning of the unauthorized access, Suffolk engaged cybersecurity experts to assist in an investigation. Suffolk completed the investigation on November 14, 2022. The investigation concluded that an unauthorized third party gained access to and/or exfiltrated files containing personally identifiable information (PII) for students who enrolled after 2002.

The complaint further alleges that the PII exposed in the data breach included students’ full names, Social Security Numbers, Driver License numbers, state identification numbers, financial account information, and Protected Health Information. While Suffolk did not release the total number of students affected by the data breach, the complaint alleges that approximately 36,000 Massachusetts residents were affected. No information was provided about affected out-of-state residents.

Colleges and Universities are Prime Targets for Cybercriminals

Unfortunately, Suffolk’s data breach is not an outlier. Colleges and universities present a wealth of opportunities for cyber criminals because they house massive amounts of sensitive data, including employee and student personal and financial information, medical records, and confidential and proprietary data. Given how stolen data can be sold through open and anonymous forums on the Dark Web, colleges and universities will continue to remain prime targets for cybercriminals.

Recognizing this, the FBI issued a warning for higher education institutions in March 2021, informing them that cybercriminals have been targeting institutions of higher education with ransomware attacks. In May 2022, the FBI issued a second alert, warning that cyber bad actors continue to conduct attacks against colleges and universities.

Suffolk Allegedly Breached Data Protection Duty

In the complaint, Plaintiff alleges that Suffolk did not follow industry and government guidelines to protect student PII. In particular, Plaintiff alleges that Suffolk’s failure to protect student PII is prohibited by the Federal Trade Commission Act, 15 U.S.C.A. § 45 and that Suffolk failed to comply with the Financial Privacy Rule of the Gramm-Leach-Bliley Act (GLBA), 15 U.S.C.A. § 6801. Further, the suit alleges that Suffolk violated the Massachusetts Right to Privacy Law, Mass. Gen. Laws Ann. ch. 214, § 1B, as well as its common law duties.

How Much Cybersecurity is Enough?

To mitigate cyber risk, colleges and university must not only follow applicable government guidelines but also consider following industry best practices to protect student PII.

In particular, GLBA requires a covered organization to designate a qualified individual to oversee its information security program and conduct risk assessments that continually assess internal and external risks to the security, confidentiality and integrity of personal information. After the risk assessment, the organization must address the identified risks and document the specific safeguards intended to address those risks. See 16 CFR § 314.4.

Suffolk, as well as other colleges and universities, may also want to look to Massachusetts law for guidance about how to further invest in its cybersecurity program. Massachusetts was an early leader among U.S. states when, in 2007, it enacted the “Regulations to safeguard personal information of commonwealth residents” (Mass. Gen. Laws ch. 93H § 2) (Data Security Law). The Data Security Law – still among the most prescriptive general data security state law – sets forth a list of minimum requirements that, while not specific to colleges and universities, serves as a good cybersecurity checklist for all organizations:

Designation of one or more employees responsible for the WISP.
Assessments of risks to the security, confidentiality and/or integrity of organizational Information and the effectiveness of the current safeguards for limiting those risks, including ongoing employee and independent contractor training, compliance with the WISP and tools for detecting and preventing security system failures.
Employee security policies relating to protection of organizational Information outside of business premises.
Disciplinary measures for violations of the WISP and related policies.
Access control measures that prevent terminated employees from accessing organizational Information.
Management of service providers that access organizational Information as part of providing services directly to the organization, including retaining service providers capable of protecting organizational Information consistent with the Data Security Regulations and other applicable laws and requiring service providers by contract to implement and maintain appropriate measures to protect organizational Information.
Physical access restrictions for records containing organizational Information and storage of those records in locked facilities, storage areas or containers.
Regular monitoring of the WISP to ensure that it is preventing unauthorized access to or use of organizational Information and upgrading the WISP as necessary to limit risks.
Review the WISP at least annually or more often if business practices that relate to the protection of organizational Information materially change.
Documentation of responsive actions taken in connection with any “breach of security” and mandatory post-incident review of those actions to evaluate the need for changes to business practices relating to protection of organizational Information.

An organization not implementing any of these controls should consider documenting the decision-making process as a defensive measure. In implementing these requirements and recommendations, colleges and universities can best position themselves to thwart cybercriminals and plaintiffs alike.

Louisiana’s Largest Medical Complex Discloses Data Breach Associated to October Attack

On December 23rd, 2022, the Lake Charles Memorial Health System (LCMHS) began sending out notifications regarding a newly discovered data breach that is currently impacting approximately 270,000 patients. LCMHS is the largest medical complex in Lake Charles, Louisiana, which contains multiple hospitals and a primary care clinic. The organization discovered unusual activity on their network on October 21, 2022, and determined on October 25, 2022, that an unauthorized actor gained access to the organization’s network as well as “accessed or obtained certain files from [their] systems.” The LCMHS notice listed the following patient information as exposed: patient names, addresses, dates of birth, medical record or patient identification numbers, health insurance information, payment information, limited clinical information regarding received care, and Social Security numbers (SSNs) in limited instances. While LCMHS has yet to confirm the unauthorized actor responsible for the data breach, the Hive ransomware group listed the organization on their data leak site on November 15, 2022, as well as posted files allegedly exfiltrated after breaching the LCMHS network. The posted files contained “bills of materials, cards, contracts, medical info, papers, medical records, scans, residents, and more.” It is not unusual for Hive to claim responsibility for the associated attack as the threat group has previously targeted hospitals/healthcare organizations. CTIX analysts will continue to monitor the Hive ransomware group into 2023 and provide updates on the Lake Charles Memorial Health System data breach as necessary.

Threat Actor Activity

Kimsuky Threat Actors Target South Korean Policy Experts in New Campaign

Threat actors from the North Korean-backed Kimsuky group recently launched a phishing campaign targeting policy experts throughout South Korea. Kimsuky is a well-aged threat organization that has been in operation since 2013, primarily conducting cyber espionage and occasional financially motivated attacks. Aiming their attacks consistently at entities of South Korea, the group often targets academics, think tanks, and organizations relating to inter-Korea relations. In this recent campaign, Kimsuky threat actors distributed spear-phishing emails to several well-known South Korean policy experts. Within these emails, either an embedded website URL or an attachment was present, both executing malicious code to download malware to the compromised machine. One (1) tactic the threat actors utilized was distributing emails through hacked servers, masking the origin IP address(es). In total, of the 300 hacked servers, eighty-seven (87) of them were located throughout North Korea, with the others from around the globe. This type of social engineering attack is not new for the threat group as similar instances have occurred over the past decade. In January 2022, Kimsuky actors mimicked activities of researchers and think tanks in order to harvest intelligence from associated sources. CTIX continues to urge users to validate the integrity of email correspondence prior to visiting any embedded emails or downloading any attachments to lessen the risk of threat actor compromise.

Netgear Patches Critical Vulnerability Leading to Arbitrary Code Execution

Network device manufacturer Netgear has just patched a high-severity vulnerability impacting multiple WiFi router models. The flaw, tracked as CVE-2022-48196, is described as a pre-authentication buffer overflow security vulnerability, which, if exploited, could allow threat actors to carry out a number of malicious activities. These activities include stealing sensitive information, creating Denial-of-Service (DoS) conditions, as well as downloading malware and executing arbitrary code. In past attacks, threat actors have utilized this type of vulnerability as an initial access vector by which they pivot to other parts of the network. Currently, there is very little technical information regarding the vulnerability and Netgear is temporarily withholding the details to allow as many of their users to update their vulnerable devices to the latest secure firmware. Netgear stated that this is a very low-complexity attack, meaning that unsophisticated attackers may be able to successfully exploit a device. CTIX analysts urge Netgear users with any of the vulnerable devices listed in Netgear’s advisory to patch their device immediately.

Uber Discloses New Data Breach Related to Third-Party Vendor

Uber has disclosed a new data breach that is related to the security breach of Teqtivity, a third-party vendor that Uber uses for asset management and tracking services. A threat actor named “UberLeaks” began leaking allegedly stolen data from Uber and Uber Eats on December 10, 2022, on a hacking forum. The exposed data includes Windows domain login names and email addresses, corporate reports, IT asset management information, data destruction reports, multiple archives of apparent source code associated with mobile device management (MDM) platforms, and more. One document in particular contained over 77,000 Uber employee email addresses and Windows Active Directory information. UberLeaks posted the alleged stolen information in four (4) separate postings regarding Uber MDM, Uber Eats MDM, Teqtivity MDM, and TripActions MDM platforms. The actor included one (1) member of the Lapsus$ threat group in each post, but Uber confirmed that Lapsus$ is not related to this December breach despite being previously linked to the company’s cyberattack in September 2022. Uber confirmed that this breach is not related to the security incident that took place in September and that the code identified is not owned by Uber. Teqtivity published a data breach notification on December 12, 2022, that stated the company is aware of “customer data that was compromised due to unauthorized access to our systems by a malicious third party” and that the third-party obtained access to its AWS backup server that housed company code and data files. Teqtivity also noted that its ongoing investigation identified the following exposed information: first name, last name, work email address, work location details, device serial number, device make, device model, and technical specs. The company confirmed that home address, banking information, and government identification numbers are not collected or retained. Uber and Teqtivity are both in the midst of ongoing investigations into this data breach. CTIX analysts will provide updates on the matter once available.

PLAY Ransomware Claims Responsibility for Antwerp Cyberattack

After last week’s ransomware attack on the city of Antwerp, a threat organization has claimed responsibility and has begun making demands. The threat group, tracked as PLAY ransomware, is an up-and-coming ransomware operation that has been posting leaked information since November 2022, according to an available posting on their leak site. Samples of the threat group’s ransomware variants have shown activity dating back to June 2022, which is around the time PLAY ransomware targeted the Argentina Court of Cordoba (August). While PLAY’s ransomware attack crippled several sectors of Antwerp, it appears to have had a significant impact on residential facilities throughout the city, as stated by officials. According to PLAY NEWS, PLAY’s ransomware leak site, the publication date for the exfiltrated data is Monday, December 19, 2022, if the undisclosed ransom is not paid. PLAY threat actors claim to have 557 gigabytes (GB) worth of Antwerp-related data including but not limited to personal identifiable information, passports, identification cards, and financial documents. CTIX continues to monitor the developing situation and will provide additional updates as more information is released.

Fortinet Patches Critical RCE Vulnerability in FortiOS SSL-VPN Products

After observing active exploitation attempts in-the-wild, the network security solutions manufacturer Fortinet has patched a critical vulnerability affecting their FortiOS SSL-VPN products. The flaw, tracked as CVE-2022-42475, was given a CVSS score of 9.3/10 and is a heap-based buffer overflow, which could allow unauthenticated attackers to perform arbitrary remote code execution (RCE) if successfully exploited. Specifically, the vulnerability exists within the FortiOS sslvpnd product, which enables individual users to safely access an organization’s network, client-server applications, and internal network utilities and directories without the need for specialized software. The vulnerability was first discovered by researchers from the French cybersecurity firm Olympe Cyberdefense who warned users to monitor their logs for suspicious activity until a patch was released. Although very few technical details about the exploitation have been divulged, Fortinet did share lists of suspicious artifacts and IPs. Based on research by Ankura CTIX analysts, the IPs released by Fortinet are located around the globe and are not associated with known threat actors at this time. To prevent exploitation, all Fortinet administrators leveraging FortiOS sslvpnd should ensure that they download and install the latest patch. If organizations cannot immediately patch their systems due to the business interruption it would cause, Olympe Cyberdefense suggests “customers monitor logs, disable the VPN-SSL functionality, and create access rules to limit connections from specific IP addresses.” A list of the affected products and their solutions, as well as the indicators of compromise can be found in the Fortinet advisory linked below.

Privacy Tip #335 – Health Care Sector Continues to Be Hit with Ransomware

According to the 2022 State of Ransomware Report issued recently by Sophos, it surveyed 5,600 IT professionals from 31 countries, including professionals in the health care sector. Those professionals in the health care sector shared that 66 percent of them had experienced a ransomware attack in 2021, which was an increase of 69 percent over 2020. This was the largest increase of all sectors surveyed.

If you look at the Office for Civil Rights data breach portal, you will see that a vast majority of breaches reported by health care providers and business associates are related to “Hacking/IT incident.” This confirms that the health care sector continues to be attacked by threat actors seeking to steal protected health information of patients.

If you are a patient who receives a breach notification letter from a health care provider or business associate, the letter will provide guidance on how to protect yourself following a data breach and may offer some protection guidance, including credit monitoring or fraud resolution. Such a letter has been sent to patients to comply with the breach notification requirements of HIPAA and state law. Part of those requirements includes that the patients be provided mitigation steps following the breach to protect themselves from fraud. Avail yourself of these protections in the event your information is compromised. Take the time to sign up for the mitigation offered. It is clear that these attacks will not subside any time soon.

Navigating the Data Privacy Landscape for Autonomous and Connected Vehicles: Implementing Effective Data Security

Autonomous vehicles can be vulnerable to cyber attacks, including those with malicious intent. Identifying an appropriate framework with policies and procedures will help mitigate the risk of a potential attack.

The National Highway Traffic Safety Administration (NHTSA) recommends a layered approach to reduce the likelihood of an attack’s success and mitigate ramifications if one does occur. NHTSA’s Cybersecurity Framework is structured around the five principles of identify, protect, detect, respond and recover, and can be used as a basis for developing comprehensive data security policies.

NHTSA goes on to describe how this approach “at the vehicle level” includes:

Protective/Preventive Measures and Techniques: These measures, such as isolation of safety-critical control systems networks or encryption, implement hardware and software solutions that lower the likelihood of a successful hack and diminish the potential impact of a successful hack.
Real-time Intrusion (Hacking) Detection Measures: These measures continually monitor signatures of potential intrusions in the electronic system architecture.
Real-time Response Methods: These measures mitigate the potential adverse effects of a successful hack, preserving the driver’s ability to control the vehicle.
Assessment of Solutions: This [analysis] involves methods such as information sharing and analysis of a hack by affected parties, development of a fix, and dissemination of the fix to all relevant stakeholders (such as through an ISAC). This layer ensures that once a potential vulnerability or a hacking technique is identified, information about the issue and potential solutions are quickly shared with other stakeholders.

Other industry associations are also weighing in on best practices, including the Automotive Information Sharing and Analysis Center’s (Auto-ISAC) seven Key Cybersecurity Functions and, from a technology development perspective, SAE International’s J3061, a Cybersecurity Guidebook for Cyber-Physical Vehicle Systems to help AV companies “[minimize] the exploitation of vulnerabilities that can lead to losses, such as financial, operational, privacy, and safety.”
