Las Vegas, Sep 12 (IANS): A massive “cybersecurity issue” at the MGM Resorts has forced the hotel and casino company to shut down its slot machines and ATMs.

The hotel guests were unable to access ATMs, buy food, or use their digital room keys.

The company notified law enforcement and "took prompt action to protect our systems and data, including shutting down certain systems.
