There was  500-line sample data published as a prove of the fact of hacking. According to Troy Hunt, who is an expert in information security, this wasn't a fake. 

The attacker gained access to company’s customer relationship management system using compromised login credential. This information was confirmed by the hacker himself.

The company representatives stated that in general 2.2 million customers were affected by the data breach. The data exposed contained:
