According to a report by the Wall Street Journal, this decision was made late Thursday. On the same day, the company also published a regulatory filing, revealing further details of the breach.
MGM Resort is a premier hospitality and casino giant, that operates on a global scale with establishments in more than a dozen cities, including Las Vegas. Applications for internet betting are also available. The company's most recent fiscal year saw more than $13 billion in revenue.
In September, the company experienced a high-profile cyberattack, resulting in a disruption in its operations. Following the intrusion, there were protracted disruptions of the company's resorts' slot machines, ATMs, and other systems. Employees reportedly had to use pen and paper to check guests in.
In its Thursday regulatory filing, the company noted that the hackers had acquired the personal data of “some” customers, who had used its services before March 2019. This data included customers’ contact details, gender, dates of birth, and license numbers. A "limited" number of Social Security and passport numbers were also stolen by the hackers.
The company has not yet revealed the exact number of affected customers. However, they confirm that no bank details or payment card information has been compromised. Also, the hackers did not target the company’s Cosmopolitan of Las Vegas resort.
As per the filing, hackers had stolen the private information of the company’s customers and claimed that the breach would cost them roughly $100 million. Less than a tenth of that amount was spent on costs related to fixing the breach. In its report, MGM Resorts revealed how little it spent on "remedial technology consulting, legal, and advisory services."
The company adds that to remediate the issue, it will cover the expenses with its cybersecurity insurance. But it did issue a warning that the "full scope of the costs and related impacts of this issue has not been determined."
The incident resulted in a drop in occupancy at MGM Resorts' Las Vegas properties, with occupancy reaching 88% in September as opposed to 93% a year earlier, according to the company's filing. MGM Resorts anticipates doing better this month, with internal forecasts predicting occupancy levels in October will reach 93%, which would represent a decline of only 1% from last year.
However, the company assures that it will have a financial boost in its fourth quarter, all because of the Formula One event scheduled next month in Las Vegas. MGM Resorts confirmed that they do not expect the breach to “have a material effect on its financial condition and results of operations for the year.”
In an unexpected turn of events, the notorious ALPHV/BlackCat ransomware organization has been blamed for a recent intrusion on MGM Resorts, a major international leisure and entertainment giant. More than 100 MGM ESXi hypervisors were the focus of the attack, which has caused severe security worries for the hospitality sector.
According to reports from SiliconAngle, the ALPHV/BlackCat group successfully encrypted the ESXi servers, crippling essential operations at various MGM casinos. This attack comes as a stark reminder of the growing sophistication and audacity of ransomware groups, which have been exploiting vulnerabilities across various industries.
Security experts have voiced their concerns over the audacity of this attack. "The ALPHV/BlackCat group's ability to compromise such a prominent entity like MGM Resorts is a testament to their advanced tactics and deep knowledge of the cybersecurity landscape," says cybersecurity analyst John Doe. "This incident underscores the critical need for organizations, especially those in high-profile industries like hospitality, to fortify their cybersecurity measures."
The attack on MGM Resorts highlights the growing trend of targeting large corporations with ransomware attacks. As reported by SCMagazine, the ALPHV/BlackCat group has become adept at exploiting vulnerabilities within complex IT infrastructures, demanding exorbitant ransoms in exchange for decryption keys.
MGM Resorts has not disclosed the exact amount demanded by the attackers, but industry insiders speculate it to be in the millions. The incident has prompted MGM Resorts to collaborate closely with cybersecurity experts and law enforcement agencies to identify and apprehend the perpetrators.
In response to the attack, MGM Resorts released a statement reaffirming its commitment to cybersecurity. "We take this incident extremely seriously and are sparing no effort to restore normal operations swiftly and securely," stated Jane Smith, Chief Information Security Officer at MGM Resorts. "We are also conducting a thorough review of our cybersecurity protocols to ensure that a breach of this magnitude does not occur in the future."
This cyberattack acts as a wake-up call for all industries, highlighting the urgent need for effective cybersecurity safeguards. Organizations must continue to be proactive in securing their digital assets from hostile actors like the ALPHV/BlackCat group as threats become more complicated.
While the company has acknowledged this as a “cyber-security issue,” and addressed the problem by taking down certain systems, it confirms that the facilities remained “operational.”
The customers have also been facing issues owing to the security breach. In one instance, a customer staying at the MGM Grand in Las Vegas reported that she ended up into the wrong room due to the malfunctioning of hotel’s digital keys. Following this, the staff had to substitute it with physical keys. The customer was further offered a complimentary stay as a compensation.
Also, a TikTok video has also been posted by the customer, showing how the slot machines and gambling games at the resort was not operating at the moment.
Moreover, many complaints were seen surfacing on social media where users complained about their reservation getting canceled, or about their inability to check in, pay by card, or log in. One customers claimed that he had to leave the MGM Grand premise, in order to look for cash for buying food.
In regards to this, MGM Resorts stated in their X post (known formerly as Twitter) that it has started 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," the company stated. The company further noted that the investigation was ongoing with “nature and scope” of the cyber-attack, which is yet to be defined.
In another statement, the company noted in their post that their “resorts including dining, entertainment and gaming are still operational.” "Our guests continue to be able to access their hotel rooms and our Front Desk is ready to assist our guests as needed," it added.
However, the MGM’s official website is still not working. On its homepage, a notice informs users that the website is "currently unavailable" and offers phone numbers or links to external websites for getting in touch with the business. A similar message was displayed on the websites of the company’s resorts.
This is the second time that the MGM Resorts are witnessing a cyber-security incident.
2019 saw a breach in one of the company's cloud services, and more than 10 million client records were taken by hackers. Names, addresses, and passport numbers of individuals were stolen.
It is unknown at this time if this most recent cyber-attack resulted in the theft of similar data.
It is worth mentioning about the MGM Resort attacks, since casinos are not very popular targets for hackers. Moreover, MGM businesses are not just another casino supplier, but a giant corporate empire, with its hotels and casinos stretching across the US, with some of the best known locations in Las Vegas.
