SAN FRANCISCO/WASHINGTON (Reuters) - A hacking group named Scattered Spider brought down the systems of the $14 billion gaming giant MGM Resorts International this week, two sources familiar with the matter said, as U.S. law enforcement officials started a probe into the breach.

Several MGM systems remained paralyzed for a third straight day after it said on Monday it had shut some of them to contain a "cybersecurity issue." The company, which operates over 30 hotel and gaming venues around the world including in Macau and Las Vegas, said it was investigating the incident.
