The official developer forum of Dota2 (Defense of the Ancients 2), multiplayer online battle arena video game suffered a massive data breach in which personal data of 1,923,972 million users was stolen.

The Dota2 developers have acknowledged the hack and reset the passwords for all forum user accounts. The security notice clarifies that users’ payment and Steam credentials were not stolen, yet, they have warned users about changing their passwords on other sites in case they have been using same passwords.
”We have recently been made aware that a vulnerability in the Dota 2 Dev forum software allowed access to the forum database. The vulnerability has been patched. The database contains email addresses, forum usernames, salted forum password hashes, and forum posts. The database relates only to the Dota 2 Dev forums at dev.dota2.com and does not contain any Steam credentials, payment information or any other private information related to your Steam account. We have reset the passwords for all forum user accounts. If you used your forum password for other online services, we recommend you change those passwords as well.”
