Email addresses and hashed passwords of more than 92 million MyHeritage users were exposed in a cybersecurity breach on October 26, 2017, the popular genealogy company reported Monday, June 4, 2018.

MyHeritage said that it only learned of the breach earlier that day—more than seven months after the fact—when an unidentified “security researcher” sent the company’s chief information security officer a message. The researcher said they had found a file containing users’ data on a private server and passed a copy of the file along.
