City of Hamilton Informs Water Customers of Ransomware Attack

August 30, 2022


The City of Hamilton alerted customers of a recent ransomware attack connected with a third party vendor that sends emails to water customers. In a release, staff say the “possible data breach” may have ties to Neptune Technology Group, who replace and maintain water meters, and a third-party mailing vendor that informs residents of a need to replace a meter. The city said “Hamilton Water considers this is a low-risk incident for residents, but felt it important to inform the community." It’s believed 2,387 out of about 156,000 accounts may have been subject to attack giving access to personal information like names and mailing addresses. Neptune Technology Group has stopped using and sharing information with the mailing vendor as a precaution.
