We want to draw your attention to the recent ransomware attack on a third-party IT service provider that has impacted over 60 credit unions and their ability to service their members. Here are some practical security recommendations to help ensure your organization is well-prepared against similar threats.

1. Prioritize Patch Management: It's essential to have a robust patch management system in your organization. The recent attack exploited a vulnerability in Citrix networking products. Regularly update your system patches to safeguard against both known and unknown vulnerabilities.
2. Stay Informed about Vulnerabilities: Keep your cybersecurity team informed about potential flaws in widely used platforms or software. In this instance, the attack was linked to CVE-2023-4966 (CitrixBleed). Stay updated on security advisories and take prompt action to mitigate potential risks.
3. Incident Response Preparedness: Develop and regularly update an incident response plan tailored to your organization's needs. Effectively responding to a security incident is crucial for minimizing impact and downtime.
4. Proactive Threat Detection: Implement monitoring techniques and proactive threat hunting measures. This allows you to address risks proactively before they cause harm.
5. Collaborate with Regulatory Bodies: Establish communication channels with regulatory bodies. In this case, the National Credit Union Administration (NCUA) promptly reported the incident to the FBI and CISA. Collaborating with law enforcement enhances our collective capacity to respond to and resolve cyber threats.

Remember, the impact of a cybersecurity incident can be significantly reduced through early detection. Cybersecurity is a shared responsibility, and being proactive is the most effective way to defend against evolving threats. If you have any concerns or inquiries, feel free to reach out to our team.
