What happened
In December 2016, the forum for the public blockchain-based distributed computing platform Ethereum suffered a data breach. The database contained over 16k unique email addresses along with IP addresses, private forum messages and (mostly) bcrypt hashed passwords. Ethereum elected to self-submit the data to HIBP, providing the service with a list of email addresses impacted by the incident.

Recommended actions
- Change your Ethereum 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 Ethereum — attackers weaponise breach data quickly.
- Check whether your email address appears in this breach on haveibeenpwned.com.
