Ticketmaster has been warning some Canadian customers that their data may have been compromised during a recent security breach. An email sent by the ticket sales platform to customers this week reveals "an unauthorized third party" snagged information from a cloud database hosted by an unnamed third-party data services provider sometime between April 2 and May 18. The email said the company determined on May 23 that some of its customers' names, basic contact information, and payment card information such as encrypted credit or debit card numbers and expiration dates were part of the breach. "We are fully committed to protecting your information, and deeply regret that this incident occurred," the email said. The missive comes months after Live Nation, Ticketmaster's Beverly Hills, Calif.-based parent company, said in regulatory filings that on May 27 "a criminal threat actor'' offered to sell Ticketmaster data on the dark web.
