Expert Insights:

Dr. Greg Moody, an associate professor of information systems and cybersecurity at the University of Nevada, Las Vegas, suggested that a “cybersecurity issue” typically indicates an attack on the company’s network. In this case, the attacker(s) may have exploited vulnerabilities in MGM’s security measures to compromise its systems. Such cyberattacks are often motivated by financial gain, involving data theft and ransom demands.

Dr. Arthur Salmon, a professor of computing and information technology at the College of Southern Nevada, emphasized that large businesses, including casinos, are common targets due to the potential reputational harm resulting from data breaches. Security breaches can have significant consequences for customer privacy, making them lucrative targets for cybercriminals.

Yoohwan Kim, a professor of network security at the University of Nevada, Las Vegas, highlighted a common tactic employed by attackers. They may steal data from a financially secure company, demand a ransom for decryption keys, and wait for payment. Ransom amounts can range from hundreds of thousands to low millions for larger companies.


Recovering from a widespread cybersecurity attack can be a prolonged and arduous process, often taking months or even years to fully mitigate the damage. Cyberattacks can disrupt operations, compromise sensitive data, and erode customer trust, requiring comprehensive efforts to restore normalcy and security.
