What Happened

In June 2012, the multiplayer online game League of Legends suffered a data breach. At the time, the service had more than 32 million registered accounts and the breach affected various personal data attributes including "encrypted" passwords. In 2018, a 339k record subset of the data emerged with email addresses, usernames and plain text passwords, likely cracked from the original cryptographically protected ones.
