Ticketmaster hit by cyberattack that compromised user data

Live Nation, the parent company of Ticketmaster, announced Friday evening that it had been the victim of a cyberattack in which user data was compromised.

The company said in a filing with the U.S. Securities and Exchange Commission (SEC) that it discovered “unauthorized activity within a third-party cloud database” on May 20 and immediately launched an investigation.

A week later, “a criminal threat actor offered Live Nation purported user data for sale via the dark web,” the filing states.

“As of the date of this filing, the incident did not have, and we do not expect it will have, a material impact on our overall business operations or financial condition or results of operations. We continue to assess the risks and our remediation efforts are ongoing,” Live Nation said in the filing.

The investigation is ongoing. No suspects have been identified yet.

The FBI declined ABC News’ request for comment. The Cybersecurity and Infrastructure Security Agency (CISA) referred questions to Ticketmaster.

Experts told ABC News that the data theft did not appear to be that serious.

According to experts, no financial or medical data appears to have been stolen.

The experts said customers can protect themselves from this type of online attack by changing their passwords frequently, using two-factor authentication when possible and keeping their financial information private from online advertisers.

The alleged data theft occurred three days before the Justice Department and dozens of state attorneys general filed lawsuits seeking to break up Ticketmaster.

The lawsuit alleges that the company created a monopoly on ticket prices for live entertainment, thereby harming consumers.

Live Nation denied the allegations in the lawsuit and said other factors, including bootlegging and higher production costs, were responsible for the higher prices.
