by | Oct 1, 2023 | Cybersecurity

In the heart of Las Vegas, amidst the dazzling lights and vibrant nightlife, a different kind of drama unfolded at MGM Resorts. This wasn’t the plot of a blockbuster movie, but a real-world cybersecurity incident that sent shockwaves through the hospitality and entertainment giant. It was breached by the “Scattered Spider,” also known as UNC3944, impacting the $14 billion gaming giant’s systems for quite a while.

In this article, we’ll delve into the details of the MGM cybersecurity incident, dissect its impact, and explore the response from relevant organizations. Furthermore, we’ll unravel the valuable lessons that can be gleaned from this breach and offer insights into how businesses can bolster their cybersecurity strategies to thwart such threats in the future.

The Extent of the MGM Cybersecurity Incident

MGM Resorts, a $14 billion gaming giant operating over 30 hotels and gaming venues worldwide, recently fell victim to a malicious cyber intrusion. The extent of the MGM cybersecurity incident sent shockwaves through the industry and beyond.

It disrupted not only the operations of this hospitality and entertainment behemoth but also raised concerns about the vulnerability of large organizations to cyberattacks. The attack resulted in several MGM systems remaining paralyzed for an extended period.

Among the casualties were:

  • Corporate email systems,
  • Restaurant reservation platforms,
  • Hotel booking systems, and even
  • Digital room keys.

The repercussions were not confined to the digital realm; they spilled over into the physical world, causing massive inconveniences for guests trying to check in and out of their rooms. CISOs were paramount for recovery, not only of the digital systems, but many physical aspects as well.

The financial ramifications were equally staggering. MGM Resorts reported that it typically brought in approximately $25 million per day in the third quarter of 2022. With its systems offline and resort functions disrupted, the company incurred substantial financial losses.

Casino gambling, a primary revenue source in Las Vegas, was adversely affected at the affected resorts. Furthermore, the disruption cast a shadow of uncertainty over employee salaries, with concerns that they might not be paid on time due to the company’s size and the financial impact of the breach.

How the Cyberattack Occurred

What makes this cybersecurity incident even more concerning is the method employed by the attackers. The MGM breach was a social engineering attack, a technique as old as hacking itself, yet one that continues to be highly effective.

An affiliate of the Black Cat/AlphV ransomware gang, known as Scattered Spider, reportedly claimed responsibility for the attack. Scattered Spider used LinkedIn to identify employees and engaged in a 10-minute conversation with the IT help desk, spoofing their identity. Timing played a crucial role in the success of this attack; it occurred on the weekend when hotel IT systems were most vulnerable.

The attack didn’t stop at social engineering; the hackers were able to exploit remote login software and leaked VPN account information from MGM employees to infiltrate the company’s systems. It’s noteworthy that this same group had previously targeted Caesars Entertainment, another major player in the casino industry, which reportedly paid a substantial ransom to the hackers who attacked its systems.

Key Takeaways & Lessons Learned

In the wake of the MGM Resorts cybersecurity incident, where even a colossal industry leader could fall prey to digital malevolence, there are profound takeaways that resonate for businesses, especially those navigating the complex cyber landscape:

1. The Illusion of Invulnerability

The MGM incident dispels the illusion that some organizations might harbor—the belief that they are immune to cyber threats due to their size, prominence, or industry. It’s a stark wake-up call that underscores the universality of cyber risks for IT teams of all sizes.

The lesson here is that no entity, regardless of its stature, can afford complacency. Every business, big or small, is potentially in the crosshairs of cybercriminals. Cyberattacks do not discriminate; they seek vulnerabilities wherever they exist.

2. A Proactive Stance is Imperative

The increased prevalence of cyber-threats means that waiting to react when a cyber threat strikes is an inadequate strategy. Instead, organizations must adopt a proactive cybersecurity approach. Proactivity entails keeping technology infrastructure up to date, but it’s more than just the latest software patches.

It involves actively seeking out and understanding the evolving tactics and techniques employed by cyber adversaries. This awareness equips businesses to anticipate and preempt attacks rather than simply reacting to them. In essence, being proactive means being prepared.

3. The Human Factor: Employee Vigilance

While technology plays a significant role in cybersecurity, the human factor remains paramount. Cybercriminals are astute at exploiting the psychological vulnerabilities of employees through tactics like social engineering.

Thus, ongoing, comprehensive employee education is not just advisable; it’s indispensable. This education extends beyond merely recognizing the signs of phishing emails; it’s about instilling a culture of cyber-awareness throughout the organization.

Employees are often the first line of defense, and their vigilance can be a potent shield against cyber threats. Similarly, controlling Shadow IT is key to improving internal cybersecurity. For this, CIOs, CISOs, CEOs, and CFOs will need to collaborate and ensure all the necessary IT equipment is present on-site.

4. Constant Vigilance Through Audits

Regular security audits, encompassing penetration testing and vulnerability assessments, are akin to health check-ups for an organization’s digital infrastructure. They serve as diagnostic tools, identifying potential vulnerabilities before they can be exploited by malicious actors.

These audits are not one-time events but should be integrated into the organization’s cybersecurity posture as an ongoing practice. By constantly probing and scrutinizing their defenses, businesses can ensure that their digital fortifications remain resilient against ever-evolving threats.

5. Preparing for the Worst: Incident Response Planning

The MGM incident underscores the indispensable need for a well-prepared incident response plan. Cyberattacks are not a matter of “if” but “when” for most organizations. How an organization responds when the inevitable occurs can make the difference between recovery and devastation.

A robust incident response plan is akin to a fire drill; it ensures that everyone knows what to do when the alarm sounds. It encompasses not only the technical aspects of countering an attack but also the communication and coordination required to minimize damage and recovery time. Investing in incident response preparedness is not just a best practice; it’s a strategic imperative.

Actionable Insights for Executives

For executives, these lessons gleaned from the MGM cybersecurity incident offer actionable insights that can fortify an organization’s cybersecurity posture:

  1. Invest Wisely: Cybersecurity investments are not expenses; they are strategic investments in the organization’s longevity and reputation. Allocate resources to proactive measures, education, audits, and incident response preparedness.
  2. Leadership Starts at the Top: Cybersecurity awareness and culture start with leadership. Executives should champion and model a culture of cybersecurity consciousness, underscoring its importance throughout the organization.
  3. Agility and Adaptability: In a rapidly evolving cyber landscape, agility and adaptability are key. Be prepared to pivot and adjust strategies as new threats emerge.
  4. Partnerships and Information Sharing: Collaborate with industry peers, share threat intelligence, and stay informed about emerging cyber threats. Collective vigilance can bolster defenses.
  5. Transparency and Communication: In the event of a cyber incident, transparency and effective communication are essential. Have a clear communication plan in place to address stakeholders, including customers and employees.
  6. Simulations and Drills: Regularly conduct cybersecurity simulations and drills to test incident response readiness. These exercises can reveal weaknesses and fine-tune response strategies.

Your Business Must Remain Vigilant

The MGM Resorts cybersecurity incident serves as a stark reminder that the digital landscape is fraught with peril. In an era of evolving and increasingly sophisticated cyber threats, businesses must remain vigilant, proactive, and prepared.

This incident highlights the need for organizations to invest in robust cybersecurity measures, continuous employee education, and comprehensive incident response planning. It’s a clarion call for businesses to fortify their defenses in an age where the next cyberattack could be just around the corner, waiting to turn dreams into nightmares.
