Have I Been Pwned outlines updates to its handling of infostealer logs, including backfilling older datasets, adding an IsStealerLog flag, and cleaning data by removing entries where an email only appears on its own domain to reduce false infection signals; dashboard counts have been adjusted accordingly, and no new notifications will be sent for backfilled data, with a brief aside on reseller markups.
