Now Available: Applying 5G Cybersecurity and Privacy Capabilities Cybersecurity White Paper Series

5G technology for broadband cellular networks will significantly improve how humans and machines communicate, operate, and interact in the physical and virtual world. 5G provides increased bandwidth and capacity, and low latency. However, professionals in fields like technology, cybersecurity, and privacy are faced with safeguarding this technology while its development, deployment, and usage are still evolving.

To help, the NIST National Cybersecurity Center of Excellence (NCCoE) has launched the Applying 5G Cybersecurity and Privacy Capabilities white paper series. The series targets technology, cybersecurity, and privacy program managers within commercial mobile network operators, potential private 5G network operators, and organizations using and managing 5G-enabled technology who are concerned with how to identify, understand, assess, and mitigate risk for 5G networks. In the series we provide recommended practices and illustrate how to implement them. All of the capabilities featured in the white papers have been implemented in the NCCoE testbed on commercial-grade 5G equipment.

We are pleased to announce the following white paper which introduces the series:

Applying 5G Cybersecurity and Privacy Capabilities—Introduction to the White Paper Series

This publication explains what you can expect from each part of the series: information, guidance, recommended practices, and research findings for a specific technical cybersecurity or privacy-supporting capability available in 5G systems or their supporting infrastructures.

Simultaneously, we are also publishing the first technical white paper of the series:

Protecting Subscriber Identifiers with Subscription Concealed Identifier (SUCI)

This publication describes enabling SUCI protection, an optional capability new in 5G which provides important security and privacy protections for subscribers. 5G network operators are encouraged to enable SUCI on their 5G networks and subscriber SIMs and to configure SUCI to use a non-null encryption cipher scheme; this provides their customers with the advantages of SUCI’s protections.

Feedback Wanted

We welcome your input and look forward to your comments by September 16, 2024. We invite you to join the 5G Community of Interest (COI) and we’ll notify you when a paper in the series is being released. 

Coming Soon: Using Hardware-Based Security to Ensure 5G System Platform Integrity Whitepaper!

First Half of 2024 Ransomware Trends

Ransomware remains a prevalent threat as threat actors use extortion tactics to pressure victim organizations to pay the ransom. They deny access to encrypted files, steal data, and threaten a data breach by posting on public ransomware leak sites or releasing the stolen data to regulators, clients, or patients. The NJCCIC continues to receive reports of ransomware incidents impacting New Jersey public sector organizations, including local governments and educational institutions, and private sector organizations, including healthcare, manufacturing, construction, and third-party vendors providing critical services and resources to organizations.
For the first half of 2024, ransomware incidents reported to the NJCCIC included Akira, Play, Qilin, INC, and Clop ransomware; however, LockBit 3.0 (Black) ransomware dominated the cyber threat landscape. Threat actors exploited vulnerabilities to infiltrate systems and networks by targeting organizations running a virtual private network (VPN) service, primarily lacking proper MFA implementation. Other reported points of entry were users clicking on phishing and malvertising links.
Once threat actors gained unauthorized access, they infiltrated the target organization, gained access to internal systems, and moved laterally to other critical systems. Once they exfiltrated data, they encrypted systems and servers, shutting down access to essential services and files containing personally identifiable information (PII) and financial information. Other impacted systems and information included emergency communications, transportation, human resources, employee records, payroll, and student information. Additionally, the ransomware incidents affected onsite backups; therefore, victim organizations had to resort to offsite backups, if available and viable for restoration.
Heading into the second half of 2024, the NJCCIC has received similar ransomware reports of LockBit 3.0 (Black) and Rhysida ransomware as threat actors continue targeting public sector organizations and phishing for PII and VPN credentials.
Recommendations
Establish a comprehensive data backup plan that includes regularly performing scheduled backups, keeping an updated copy offline in a separate and secure location, and testing it regularly. Avoid clicking links, responding to, or otherwise acting on unsolicited emails. Keep systems up to date and apply patches after appropriate testing. Use strong, unique passwords for all accounts and enable MFA where available, choosing authentication apps or hardware tokens over SMS text-based codes. Utilize network segmentation to isolate valuable assets and help prevent the spread of ransomware and malware. Enforce the principle of least privilege, disable unused ports and services, and use web application firewalls (WAFs). Maintain robust and up-to-date endpoint detection tools on every endpoint. Consider leveraging behavior-based detection tools rather than signature-based tools. Report ransomware and other malicious cyber activity to the FBI’s IC3 and the NJCCIC.

Recent Tycoon 2FA Phishing Campaigns Target Government Entities

Image Source: Any.Run LinkedIn Blog Post
A sophisticated phishing campaign targeting Microsoft Teams was identified using the Tycoon 2FA Phish-kit phishing-as-a-service (PhaaS) platform to steal session cookies and bypass two-factor authentication (2FA) protection. After clicking on a phishing link, the victim is prompted to enter their email on the threat actor-controlled phishing page, MSOFT_DOCUSIGN_VERIFICATION_SECURED-DOC_OFFICE[.]zatrdg[.]com (Any.Run interactive analysis ). If the email used to authenticate is on the specified target list, the victim is redirected to an obfuscated phishing domain, such as donostain[.]com, requesting their Microsoft account password. This website redirects to a Tycoon 2FA phishing page or a legitimate domain. Another recent tactic is exploiting “Error 500” or “no Internet Connection” messages. After attempting to refresh the page, the victim is redirected to a fake Microsoft 365 Outlook phishing website to steal credentials if entered. Some of these phishing websites may also include a CAPTCHA solution.
An additional recently identified campaign uses Amazon Simple Email Service (SES) and high-profile redirects to steal user credentials. The attack chain is designed to avoid detection, involving multiple stages and using compromised domains and services. According to a phishing sample analysis, the attack begins with an email from an Amazon SES client. These emails often contain a valid signature, adding to their appearance of legitimacy. The email usually includes two empty PDF attachments and a message from Docusign stating, “You have received a document to review and sign.” Despite occasionally failing SPF and DKIM checks, these emails may still appear legitimate due to the compromised source. Based on a report by Any.Run, when the “Review Document” link is clicked, victims are rerouted through a complex series of URLs to obscure the final phishing domain.
Recommendations
Avoid relying solely on SPF and DKIM checks to validate emails, as the source email may be compromised. Avoid responding to messages, clicking links, or opening attachments from unknown or unverified senders, and exercise caution with emails from known senders. Confirm the legitimacy of requests by contacting the sender via a separate means of communication, such as by phone, using contact information obtained from official sources before responding, divulging sensitive information, or providing funds. Navigate directly to legitimate websites and verify before submitting account credentials or providing personal or financial information. Use strong, unique passwords and enable multi-factor authentication (MFA) where available, choosing authentication apps or hardware tokens over SMS text-based codes. Reduce your digital footprint so that threat actors cannot easily target you. Report malicious cyber activity to the FBI’s IC3 and the NJCCIC.

Elder Fraud Scams Persist

The NJCCIC received reports involving elder fraud scams that reflect recent tactics observed by the FBI. The scammers typically employ a multi-layered approach, impersonating associates of a technology company, a financial institution, and a US government official in sequence, a tactic commonly referred to as the “Phantom Hacker ” scam. The scammers may claim that the victim’s financial accounts were compromised or are at risk of being compromised, and, as a result, their funds need to be protected. In one reported incident, the scammers claimed to be federal investigators who had obtained a warrant for the arrest of the victim shortly after a close family member passed away.  
The scammers typically persuade victims to liquidate their assets into cash or invest in gold, silver, or other precious metals. In some instances, the victims were instructed to wire funds to a precious metal dealer who claimed to ship the purchased commodities to the victims’ residences. Once a victim obtains the cash or precious metals, the scammers send couriers to retrieve the items at the victim’s home or a public location. The victim is assured that their assets will be protected in a secure account; however, the scammers sever contact shortly after the transaction, causing the victims to suffer significant financial losses.
Between May and December 2023, the FBI’s Internet Crime Complaint Center (IC3) observed a significant increase in these fraudulent activities, resulting in combined losses exceeding $55 million. A similar incident was recently reported to the New Jersey State Police, involving a scammer who stole $13,000 from a victim in Hunterdon County, NJ, after the victim received a virus alert pop-up notification.   Recommendations  
Educate yourself and others about these and similar scams. The US government and legitimate businesses will never request you to purchase gold or other precious metals. Refrain from clicking on or contacting unknown telephone numbers found in unsolicited pop-up notifications, or links and attachments delivered via emails or text messages. Avoid downloading software at the request of unknown individuals, and refrain from allowing them to access your computer. Confirm the legitimacy of requests by contacting the sender via a separate means of communication, such as by phone, using contact information obtained from official sources before responding, divulging sensitive information, or providing funds.
Report malicious cyber activity to the FBI’s IC3 and the NJCCIC as quickly as possible to increase the likelihood of recovering funds. Be sure to include as much transaction information as possible, such as: The name of the person or company that made contact. Methods of communication used, including websites, emails, and telephone numbers. Any bank account numbers and the recipients’ names who received the wired funds. The name and location of the metal dealer company and the receiving account number if funds were wired to buy precious metals. Victims aged 60 or over who require assistance filing an IC3 complaint can contact the DOJ Elder Justice Hotline at 1-833-FRAUD-11 (833-372-8311).   .

Review software versions monthly, or more frequently, to verify software support.
    • Safeguard 18.1: Establish and Maintain a Penetration Testing Program: Establish and maintain a penetration testing program appropriate to the size, complexity, and maturity of the enterprise. Penetration testing program characteristics include scope, such as network, web application, Application Programming Interface (API), hosted services, and physical premise controls; frequency; limitations, such as acceptable hours, and excluded attack types; point of contact information; remediation, such as how findings will be routed internally; and retrospective requirements.
    • Safeguard 18.2: Perform Periodic External Penetration Tests: Perform periodic external penetration tests based on program requirements, no less than annually. External penetration testing must include enterprise and environmental reconnaissance to detect exploitable information. Penetration testing requires specialized skills and experience and must be conducted through a qualified party. The testing may be clear box or opaque box.
    • Safeguard 18.3: Remediate Penetration Test Findings: Remediate penetration test findings based on the enterprise’s policy for remediation scope and prioritization.
       
  • Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. (M1026: Privileged Account Management)
    • Safeguard 4.7: Manage Default Accounts on Enterprise Assets and Software: Manage default accounts on enterprise assets and software, such as root, administrator, and other pre-configured vendor accounts. Example implementations can include: disabling default accounts or making them unusable.
