SAN FRANCISCO (Reuters) - Live Nation Entertainment said on Friday it was investigating a data breach at its Ticketmaster unit that it discovered on May 20, the latest in a string of high-profile corporate hacks in the past year.

In a filing with the U.S. Securities and Exchange Commission, Live Nation said it found "unauthorized activity" in a third-party cloud database that mainly contained Ticketmaster data, and was working with forensic investigators.
