LAS VEGAS (AP) — Casino company Caesars Entertainment has joined Las Vegas gambling rival MGM Resorts International in reporting a recent cyberattack. But while some MGM Resorts computer systems were still down, Caesars told federal regulators on Thursday that its casino and online operations were not disrupted. The Reno-based company told the federal Securities and Exchange Commission that it can’t guarantee that personal information about tens of millions of customers is secure. Cybersecurity threat experts say hackers claiming responsibility for both attacks appear to be an English-speaking group and a Russia-based parent operation. Caesars has more than 65 million loyalty customers and has properties in 18 states and Canada — along with mobile, online and sports betting operations.
