The compromised details from this breach for affected accounts include email address, encrypted account password, summoner name, date of birth, and a small number of players may have also had their first and last name and encrypted security question and answer compromised. Luckily, no payment or billing information was compromised in the breach.
Riot Games has posted an apology to the community for the breach and a list of the actions that they’ve taken. Players that had their accounts contained in the affected databases should receive an email over the next day even if they were not part of those affected with instructions to change their password, something that Riot Games is suggesting that all League of Legends players do as a precaution.
