What happened in Have I Been Pwned’s words
In April 2026, home security firm ADT confirmed a data breach by ShinyHunters, which listed the company on its website as part of a "pay or leak" extortion attempt. The breach impacted 5.5M unique email addresses along with names, phone numbers and physical addresses. ADT also advised that "in a small percentage of cases, dates of birth and the last four digits of Social Security numbers or Tax IDs were included" and that it had contacted all affected people.
