Dota2 Data Breach

What happened

In July 2016, the Dota2 official developers forum suffered a data breach that exposed almost 2 million users. The hack of the vBulletin forum led to the disclosure of email and IP addresses, usernames and passwords stored as salted MD5 hashes.

Exposed data

Recommended actions

• Change your Dota2 password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Dota2 — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
