In the days before the Knicks won the N.B.A. finals, sending New York City into a rapture, a hacking group was quietly working to steal data from Madison Square Garden, including the records of celebrities and other customer information, according to three class-action lawsuits filed against the companies that own the arena and sports teams. ShinyHunters, a hacking group, claimed responsibility for the attack and announced on June 12 that if it did not receive a ransom from the Garden, more than 26 million records would be leaked. On June 16, ShinyHunters sent a new message: “It’s very simple. When you pay us, your data is deleted, and you move on with your life. When you don’t pay us, you get posted here, among other things.”

Full report : Hackers stole more than 45GB of data from Madison Square Garden, including data related to “talent” and the Knicks.
