DentaQuest Group, Inc. (“DentaQuest”), part of Sun Life U.S., is a dental benefits administrator and dental insurance provider based in Wellesley Hills, Massachusetts. It recently experienced a data security incident, potentially impacting some DentaQuest clients’ sensitive data.
In May 2026, hacking/extortion group ShinyHunters listed DentaQuest on its Dark Web data leak site. According to an article by technology news outlet Bleeping Computer, ShinyHunters claims to have stolen more than 234GB of data from DentaQuest. ShinyHunters later published the stolen data, the article says. On June 2, 2026, DentaQuest confirmed a breach occurred. Data breach monitoring site HaveIBeenPwned reviewed the leaked data and reports that 2.6 million unique email addresses were compromised in addition to names, genders, dates of birth, health insurance information, government-issued IDs, phone numbers, and physical addresses.
