Credit unions have long stood as bastions of trust in the financial services industry, built on a foundation of member-centric values and community service. Their commitment to safeguarding member data is not just a regulatory requirement but a cornerstone of their operational philosophy. However, the landscape of cybersecurity threats targeting credit unions has evolved dramatically in recent years, with increasingly sophisticated attacks specifically designed to exploit vulnerabilities in financial systems.
Credit unions now face a perfect storm of cybersecurity challenges:
- They hold valuable financial and personal data but often operate with more limited security resources than larger banking institutions
- This combination makes them particularly attractive targets for cybercriminals seeking high-value data with potentially lower barriers to entry
- According to IBM, financial services firms are 300 times more likely to be targeted by a cyber attack, with an average breach cost of $5.9 million USD
- The National Credit Union Administration (NCUA) reported 892 cyber incidents affecting credit unions between September 2023 and May 2024, with approximately 73% of these incidents involving third-party service providers
Data Security Challenges
The sophistication of cyberattacks targeting financial institutions has reached unprecedented levels. Gone are the days when basic security measures could effectively protect sensitive financial data. In 2023, the NCUA reported a 25% increase in cybersecurity incidents at credit unions, and this trend continues to accelerate.
Today’s threat landscape for credit unions includes:
- Advanced persistent threats specifically targeting financial data
- Ransomware attacks customized for financial institution environments, with the average ransom demand for financial institutions reaching $900,000
- Supply chain compromises affecting critical banking systems, exemplified by a 2023 ransomware attack on a cloud IT service provider that caused simultaneous outages at 60 US credit unions
- Insider threats with potential access to sensitive member information
- AI-enabled attacks using generative AI to create more sophisticated malware and social engineering campaigns that are increasingly difficult to detect
Many credit unions maintain a complex ecosystem of legacy and modern systems, creating an expanded attack surface with numerous potential entry points. This technological heterogeneity, combined with the inherent value of financial data, creates a particularly challenging security environment.
The most glaring vulnerability lies in how data is handled during active processing. While many credit unions have invested significantly in perimeter defenses, network monitoring, and endpoint protection, the data itself often remains exposed during critical operational moments.
Shortcomings of Existing Encryption Practices
Current encryption practices in most credit unions focus almost exclusively on protecting:
- Data at rest – Information stored in databases or archives
- Data in transit – Information moving between systems or users
While these approaches are necessary components of a comprehensive security strategy, they leave a critical gap in protection: data in use.
When member data is actively being processed—during transactions, account inquiries, loan applications, or everyday banking operations—it typically exists in plaintext form. This means that at the most critical moment, when members’ sensitive financial information is actively being utilized, it remains vulnerable to unauthorized access or theft. Recent high-profile breaches demonstrate this vulnerability, with Patelco Credit Union experiencing a ransomware attack that led to the compromise of personal data for approximately 1 million people, including names, Social Security numbers, driver’s license numbers, and dates of birth.
Key vulnerabilities in traditional encryption approaches:
- Data must be decrypted before it can be used or processed
- Creates windows of exposure during active operations
- Attackers can target memory or processing environments to access plaintext data
- Even strong perimeter defenses don’t protect against this fundamental vulnerability
- Compliance requirements increasingly recognize this security gap
Adopting Encryption in Use
Encryption in use represents the next evolutionary step in data security technology. Unlike traditional encryption approaches that protect data only when it’s static or moving between systems, encryption in use maintains protection while data is actively being processed or analyzed.
Benefits for credit unions:
- Comprehensive protection – Member information remains encrypted throughout its entire lifecycle
- Eliminated vulnerability windows – No moments where sensitive data exists in plaintext form
- Enhanced compliance – Supports requirements under regulations like Gramm-Leach-Bliley Act (GLBA) and emerging standards
- Operational continuity – Critical functions can continue while maintaining security
- Third-party integration – Safely leverage cloud services without exposing member data
- Advanced analytics – Enable data-driven insights while preserving privacy and security
For credit unions facing resource constraints, encryption in use technologies provide a more efficient approach to security. Rather than implementing multiple point solutions to address various security gaps, encryption in use addresses the fundamental vulnerability in data protection. This is especially important considering that, according to Arctic Wolf, 47% of executives at financial institutions report that security operations are more difficult today than they were just two years ago, highlighting the growing complexity of the security landscape.
