A hacker has leaked personal information for more than 26 million Ticketfly users after last week’s data breach. That’s according to Troy Hunt, the founder of Have I Been Pwned, which lets you check whether your email address has been included in various data breaches.

The hacker posted several Ticketfly database files to a public server, and Hunt found that they contained 26,151,608 email addresses. Many users’ names, phone numbers and home and billing addresses were also compromised.
