DataEnrichment

In December 2016, more than 200 million "data enrichment profiles" were found for sale on the darknet. The seller claimed the data was sourced from Experian and whilst that claim was rejected by the company, the data itself was found to be legitimate suggesting it may have been sourced from other legitimate locations. In total, there were more than 8 million unique email addresses in the data which also contained a raft of other personal attributes including credit ratings, home ownership status, family structure and other fields described in the story linked to above. The email addresses alone were provided to HIBP.
