Through social engineering, unknown hackers managed to reach a database backup of the official Ethereum Forum. The backup comes from April and contains information about 16,500 users. The informations are:
- Public and private messages IP addresses
- User names and email addresses
- Profile information
- And hashed passwords
The passwords of those affected were reset. If you want to know if your account is affected by this data breach, you can check it on haveibeenpwned.com.
If you use the password of forum.ethereum.org also with other services, you should change it there now.
