What happened
In April 2024, a large trove of data made headlines as having exposed "3 billion people" due to a breach of the National Public Data background check service. The initial corpus of data released in the breach contained billions of rows of personal information, including US social security numbers. Further partial data sets were later released including extensive personal information and 134M unique email addresses, although the origin and accuracy of the data remains in question.
