The data was collected as part of Exactis' service as a "compiler and aggregator of premium business & consumer data" which they then sell for profiling and marketing purposes.

Research shows that over 65% of stolen credentials from older breaches have never been changed by the account holders. Attackers routinely compile data from multiple breaches to build complete profiles, and credentials from 2018 are still actively used in credential stuffing attacks today.
