Acxiom Data Breach (2020)

A dataset consisting of nearly a quarter of a billion records spanning over 400 different fields was initially and wrongly attributed to the database marketing company Acxiom. The data, which was being circulated within hacking communities, led to claims of a breach at Acxiom. However, upon inspection, Acxiom confirmed that ""the claims are indeed false"" and the data, which was available across various platforms, did not originate from Acxiom. This data contained almost 52M unique email addresses.
