What happened in Have I Been Pwned’s words
In February 2015, the Swedish forum known as Flashback had sensitive internal data on 40k members published via the tabloid newspaper Aftonbladet. The data was allegedly sold to them via Researchgruppen (The Research Group) who have a history of exposing otherwise anonymous users, primarily those who they believe participate in "troll like" behaviour. The compromised data includes social security numbers, home and email addresses.
