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. Exposed data: email addresses, passwords, usernames. The breach dates from Jun 11, 2012; Have I Been Pwned loaded it on Jul 28, 2018.
What to do
- If you had a League of Legends account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
