Detailed Account of the Attack

The cyber incident involving Ongoing Operations, a key provider of cloud and business continuity solutions for credit unions, was a stark reminder of the risks inherent in supply-chain relationships. This ransomware attack halted Ongoing Operations’ business and disrupted the services of approximately 60 credit unions dependent on them.

It exemplifies a significant supply-chain compromise, where the trust and access granted to third-party vendors can allow threat actors to bypass an entire security stack when such a vendor gets compromised. The method of attack, potentially exploiting “Citrix Bleed” vulnerabilities, indicates a failure in securing known vulnerabilities – a common issue that can lead to catastrophic consequences.

The specifics of the ransomware used in this incident remain under investigation, but its effectiveness in disrupting operations was evident. This type of attack is particularly insidious as it halts business operations and poses a risk of sensitive data exfiltration and long-term reputational damage to the affected organizations.

Target and Scope

The primary target of this attack was Ongoing Operations, a company owned by Trellance, known for its focus on providing technology solutions to credit unions. The impact was widespread, affecting approximately 60 credit unions across the United States. These credit unions rely on Ongoing Operations for essential cloud services and business continuity solutions, making them indirect attack victims.

The scope of this incident is a grim reminder of how interconnected and dependent modern financial institutions are to third-party technology providers. This dependency amplifies the potential for widespread disruption from a single point of attack.

Method of Attack and Vulnerabilities Exploited

While the exact method of attack has not been publicly disclosed, the attackers likely exploited vulnerabilities within the network infrastructure of Ongoing Operations. One potential vulnerability that has been suggested is “Citrix Bleed.” Citrix Bleed refers to a set of security vulnerabilities in certain Citrix network appliances that threat actors have recently exploited to gain unauthorized access to networks. If this was the vector used, it would indicate a failure to adequately patch and secure known vulnerabilities, a common oversight that can have catastrophic consequences.

Immediate Consequences for Credit Unions

The ripple effects of the ransomware attack on Ongoing Operations were acutely felt across the credit union sector, leading to various operational, communicative, and customer-related challenges.

Operational Disruptions

The most direct impact was on the day-to-day operations of credit unions. A prime example was Mountain Valley Federal Credit Union (MVFCU), which experienced a complete shutdown of its data processing systems. Despite this significant setback, MVFCU demonstrated resilience by keeping certain essential services operational. They managed to maintain debit card functionality and access to cash through ATMs and physical branches. This response underscores the importance of having contingency plans in place for critical services, ensuring that basic banking functions can continue even under severe duress.

Communication and Response

The manner in which affected credit unions and their data processors responded to the crisis was crucial. In the case of MVFCU, their data processor, FedComp, played a pivotal role in communicating about the attack on Trellance. This included timely updates on the status of the attack and the ongoing efforts to restore systems.

Such transparent and prompt communication is vital in crisis situations, helping manage expectations and maintain stakeholder trust. Additionally, the collaborative effort between FedComp and Trellance in working “around the clock” to restore systems exemplifies the importance of strong partnerships and joint crisis management strategies in mitigating the impact of such attacks.

Impact on Customers and Services

The attack had a significant impact on the customers of these credit unions. While some services like ATM withdrawals and debit transactions remained available, others likely faced disruptions. This situation could have led to inconvenience and potential financial challenges for customers, especially those reliant on online banking services.

Furthermore, there was an underlying concern about the potential risks to customer data. Although there was no immediate evidence of data misuse, the uncertainty surrounding such incidents can erode customer trust and confidence. The overall customer experience during this period was undoubtedly affected.

Broader Implications for the Credit Union Sector

The ransomware attack on Ongoing Operations disrupted the operations of numerous credit unions and cast a spotlight on broader cybersecurity issues within the financial sector. Credit unions’ reliance on third-party services like those offered by Ongoing Operations creates a chain of risk, where a breach in one part can have cascading effects. This scenario shines a light on the necessity for a robust Third-Party Risk Management (TPRM) approach involving rigorous vetting, continuous monitoring, and strong security-focused contractual agreements with vendors.

Furthermore, the incident highlights the importance of adopting a zero-trust security posture. In a zero-trust model, verification is paramount, and even trusted entities are continuously authenticated and authorized. This approach can significantly mitigate the risks of supply-chain attacks by ensuring strict access controls and continuous monitoring of network activities.

Vulnerability of the Financial Sector to Cyber Threats

This incident highlights the inherent vulnerabilities within the financial sector, particularly for credit unions. Credit unions often operate with limited resources compared to larger banking institutions, impacting their ability to invest in advanced cybersecurity measures. This gap makes them potentially more susceptible to sophisticated cyber threats.

Additionally, the reliance on digital and cloud-based services, while essential for modern banking, exposes these institutions to new cyber risks. The attack underscores the need for the entire sector to reassess and fortify its cybersecurity postures, considering both internal and external threats.

The Role of Third-Party Providers in Cybersecurity

The attack also shed light on the significant role of third-party providers in the cybersecurity landscape. Like many other financial institutions, credit unions rely heavily on third-party services for critical operations, from data processing to cloud services.

This dependency creates a chain of risk; a breach in any part of this chain can have cascading effects, as seen in the Ongoing Operations incident. This scenario emphasizes the need for rigorous vetting, continuous monitoring, and strong contractual agreements focusing on security with third-party vendors.

Regulatory and Compliance Concerns

In response to the growing number of cyber incidents, regulatory bodies like the National Credit Union Administration (NCUA) have stepped up their requirements for cybersecurity. The mandate for credit unions to report cyber incidents within 72 hours is a case in point. While such regulations are crucial for timely action and mitigation, they also present challenges.

In the face of sophisticated and evolving cyberattacks, credit unions must invest in preventative cybersecurity measures, systems, and protocols that allow for rapid detection and reporting of incidents. This can be particularly challenging for smaller institutions with limited cybersecurity resources.

Strategic Considerations for Cyber Resilience

The incident is a critical learning opportunity for credit unions. It exemplifies the importance of conducting comprehensive risk assessments to understand and prepare for potential cyber threats. Building robust cyber defenses goes beyond installing firewalls and antivirus software; it involves developing a holistic security culture, regular employee training, and effective incident response plans.

Credit unions should also consider implementing multi-layered security measures, including advanced threat detection and response services, to promptly identify and mitigate threats. Strategic investments in cybersecurity protect against immediate threats and build long-term resilience and trust among members.

The recent ransomware attack is a wake-up call for the entire credit union sector. It accentuates the need for enhanced cybersecurity vigilance, proactive risk management, and adherence to regulatory requirements to safeguard against cyber threats. In collaboration with cybersecurity experts and service providers, credit unions must proactively strengthen their resilience.
