Dear Castle Rock Water customer,

Castle Rock Water was notified by Billtrust, the third-party vendor used for our H20access portal to provide customer invoicing and online bill payment, that the company experienced a malware attack in mid-October. This attack temporarily impacted the company’s ability to provide services. Billtrust is working with law enforcement and a third-party cybersecurity firm to investigate. The company’s security processes identified the issue and remediation began immediately. As of now, there is no evidence that any customer data was compromised. H20access is fully back online. There should be no additional issues with either Billtrust’s systems or the payment processing services. We will keep you updated if we receive additional information.
