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.

A Bloomberg report separately said another casino operator, Caesars Entertainment, had been hacked and paid ransom to hackers who threatened to leak its data in recent weeks, citing two people familiar with the mater.

Shares of Caesars Entertainment and MGM both fell on Wednesday.

The cause and the full impact of the breaches was not immediately clear, although social media posts showed slot machines and systems down at MGM venues in Las Vegas.

MGM Resorts on Wednesday said that a cyber incident that has significantly disrupted properties across the United States for the past three days represents a material risk to the company.

At the same time, the major credit rating agency Moody’s warned that the cyberattack could negatively affect MGM’s credit rating, saying the attack highlighted “key risks” within the company.

The company’s corporate email, restaurant reservation and hotel booking systems remain offline as a result of the attack, as do digital room keys. MGM on Wednesday filed a 8-K report with the Securities and Exchange Commission noting that on Tuesday the company issued a press release “regarding a cybersecurity issue involving the Company.”

8-Ks as a rule are filed when publicly traded companies want to notify the SEC of an event that can have a material effect on the firm. An MGM spokesperson confirmed the company views the incident as material. The spokesperson declined to comment on the Moody’s warning.
