Teespring Data Breach (2021)

A hacker has leaked the details of millions of users registered on Teespring, a web portal that lets users create and sell custom-printed apparel. The user data was leaked last Sunday on a public forum dedicated to cybercrime and the sale of stolen databases. The Teespring data was made available as a 7zip archive that includes two SQL files. The first file contains a list of more than 8.2 million Teespring users' email addresses and the date the email address was last updated.
