What happened in Have I Been Pwned’s words
In April 2021, a large data set of over 500 million Facebook users was made freely available for download. Encompassing approximately 20% of Facebook's subscribers, the data was allegedly obtained by exploiting a vulnerability Facebook advises they rectified in August 2019. The primary value of the data is the association of phone numbers to identities; whilst each record included phone, only 2.5 million contained an email address. Most records contained names and genders with many also including dates of birth, location, relationship status and employer.
