Investigation notes

The City of Twin Falls is a municipal government entity responsible for providing essential public services to its residents. As a local government agency, the city collects and maintains sensitive personal information, including payroll data for employees, utility account details, and various public records containing personally identifiable information. This data breach was officially reported to the Idaho Attorney General in , and individuals whose information may have been compromised were subsequently sent a formal data breach notification letter. If you received such a letter, it indicates that your personal data held within city systems was involved in this security incident. We recommend reviewing the notification letter carefully to understand the specific scope of the exposure and the protective steps being offered by the city.

What our attorneys examine

A cyberattack does not excuse a company from protecting the information it holds. We look at whether City of Twin Falls used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in Idaho.
