Phone House España - 5,223,350 breached accounts

In April 2021, the Spanish retailer Phone House allegedly suffered a ransomware attack that also exposed significant volumes of customer data. Attributed to the Babuk ransomware, a collection of data alleged to be a subset of a larger corpus was posted to a dark web site and contained 5.2M email addresses along with names, nationalities, genders, dates of birth, phone numbers and physical addresses. Phone House has been threatened with further releases if a ransom is not paid.
