Hamilton has disclosed a data breach that may have compromised highly sensitive personal information, including Social Security numbers, medical records, and identification documents. Individuals affected may be entitled to compensation. Here’s what you need to know about the breach and your legal options.
Hamilton’s Data Breach Investigation
On June 19, 2025, Hamilton detected unauthorized access to its network, prompting an immediate investigation. The breach allowed a threat actor to access certain files on the network. Hamilton quickly launched a thorough investigation to assess the extent of the unauthorized access and whether any sensitive data had been compromised.
By October 7, 2025, a preliminary review concluded that a range of personal information had been exposed. The data compromised varied for each affected individual but included full names, Social Security numbers, driver’s license or state ID numbers, passport numbers, taxpayer identification numbers, medical information, dates of birth, and health insurance information. This level of data exposure places victims at serious risk of identity theft, financial fraud, and medical identity misuse.
After confirming the nature and extent of the breach, Hamilton began notifying individuals, including 610 Washington residents who received written notices on November 12, 2025. In response, the company notified federal law enforcement and regulatory agencies, and took steps to enhance its cybersecurity measures.
Hamilton is offering 12 months of complimentary credit monitoring and identity restoration services through Epiq, along with guidance to help affected individuals safeguard their data moving forward.
