Unreal Engine Data Breach

What happened

In August 2016, the Unreal Engine Forum suffered a data breach, allegedly due to a SQL injection vulnerability in vBulletin. The attack resulted in the exposure of 530k accounts including usernames, email addresses and salted MD5 hashes of passwords.

Exposed data

Recommended actions

• Change your Unreal Engine 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 Unreal Engine — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
