What happened

In June 2018, the massively multiplayer online role-playing game (MMORPG) Mortal Online suffered a data breach. A file containing 570k email addresses and cracked passwords was subsequently distributed online. A larger more complete file containing 607k email addresses with original unsalted MD5 password hashes along with names, usernames and physical addresses was later provided and the original breach in HIBP was updated accordingly. The data was provided to HIBP by whitehat security researcher and data analyst Adam Davies.

What data leaked

  • Email addresses
  • Names
  • Passwords
  • Physical addresses
  • Usernames

What to do if you had an account

  1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
  2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
  3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
