Ticketmaster, a California-based company, operates one of the largest online ticket sales platforms in the world.
The breach comes as Live Nation has been battling regulatory scrutiny over antitrust concerns.
The concert promoter was hit last week with the first in a likely wave of consumer antitrust lawsuits after the US government and states sued to break up the firm, arguing that along with its Ticketmaster unit, the company was illegally inflating concert ticket prices.
Live Nation in its filing said that on May 27, “a criminal threat actor offered what it alleged to be company user data for sale via the dark web”.
“We are working to mitigate risk to our users and the company, and have notified and are cooperating with law enforcement,” the company said.
“As appropriate, we are also notifying regulatory authorities and users with respect to unauthorized access to personal information.”
The breach hasn’t had and is unlikely to have a material impact on Live Nation’s business or financials, the company said.
“We continue to evaluate the risks and our remediation efforts are ongoing,” Live Nation said.
