Apparent Cyber Security Issue Hampers Operations at MGM Grand Detroit

Written By Dan Holmes on September 11, 2023 - Last Updated on September 14, 2023

An apparent cyber security threat has led to the shutdown of computer systems at MGM Grand Detroit Casino. According to reports, MGM has been made aware of a cyber security issue and has secured and shut down systems across its properties in the United States.

A phone call to MGM Grand Detroit was answered on Tuesday. A representative told PlayMichigan the slots are open but some amenities and features are closed.

A phone call to MotorCity Casino was also answered, and a customer representative explained that venue is open. It appears, based on initial reports, that only the MGM properties and MGM Grand Detroit Casino have been impacted.

Parent company MGM Resorts issued a statement on Monday that included this language:

“MGM Resorts recently identified a cybersecurity issue affecting some of the Company’s systems. Promptly after detecting the issue, we quickly began an investigation with assistance from leading external cybersecurity experts. We also notified law enforcement and took prompt action to protect our systems and data, including shutting down certain systems.

“Our investigation is ongoing, and we are working diligently to determine the nature and scope of the matter.”

CNBC reporting a “system-wide” outage

According to CNBC correspondent Contessa Brewer, the incident or threat “has caused a system-wide outage- affecting company email, reservations, booking etc. The company has contacted law enforcement and brought in outside experts.”

As of Wednesday night, the MGM Grand Detroit website displays this message: “The MGM Grand Detroit website is currently unavailable. For restaurant options and reservations, please visit here or download the MGM Rewards App.”

The cyber threat may not be limited to MGM Resorts and casinos. Messages on social media platform X (formerly Twitter), indicate that slot machines are not operational at the Borgata casino in Atlantic City. In addition, ATMs and POS systems are not functioning.

Reporting indicates that some or all of MGM properties are unable to access email and phone systems at this time.

MGM not alone in being targeted by cyber attack

Security from cyber threats is a major concern for casinos and sports betting operators like MGM and its competitors. On a daily basis a casino/resort can handle millions of dollars through its digital systems, and hundreds of millions each month.

Earlier in 2023, a serious ransomware attack led to a nearly two-week shutdown of Canada’s Gateway Casinos.

In 2020, two casinos in Las Vegas were attacked by ransomware, apparently by an overseas hacker.

We now know who hacked MGM, because they also hacked Caesars

The cybersecurity issue at MGM Grand Detroit is due to a ransomware attack by a hacker group known as Scattered Spider, or UNC3944. That group also targeted computer systems at Caesars casinos weeks ago, according to Bloomberg.
