Background

What happened in the Acumetis | SixSense Strategy Group data breach

Acumetis | SixSense Strategy Group issued a notice letter dated October 26, 2026, informing recipients of an incident that involves some of their information. The incident was reported to the Massachusetts Attorney General on October 26, 2026, and that filing lists 2 Massachusetts residents. The letter says Massachusetts law prevents the company from providing additional details regarding the event, so it does not state when the incident happened, when it was discovered, or how it occurred.

According to the letter, the information that could have been impacted includes the recipient's name and other types of information, but the posted copy of the letter shows those other types only as a placeholder. The Massachusetts filing lists financial account information and Social Security numbers. The letter says that upon discovering the incident, the company took immediate steps to secure the network, and that it is offering 24 months of complimentary credit monitoring and identity restoration services through IDX, with an enrollment deadline of January 26, 2027.

Whether Acumetis | SixSense Strategy Group's data security practices met legal standards, and what information was involved for each recipient, are among the issues being evaluated.
