Las Vegas Cyber Attack Continues Into Third Day

NBC News reports:

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.

Gizmodo reports:

The ransomware group, ALPHV also known as BlackCat, is reportedly behind the cyber attack that shut down MGM Grand casinos on Monday, according to a report by malware archive vx-underground. The archive claims ALPHV was able to social-engineer their way into the company’s systems in 10 minutes, effectively shutting down MGM Resorts International properties across the U.S.

The ransomware group allegedly took hold of MGM’s computer systems in three simple steps, according to vx-underground. “All ALPHV ransomware group did to compromise MGM Resorts was hop on LinkedIn, find an employee, then call the Help Desk,” the organization wrote in a Twitter post. “A company valued at $33,900,000,000 was defeated by a 10-minute conversation,” it added.

TikTok today is flooded with videos showing hours-long lines at multiple Las Vegas hotels as staffers attempt to manually check in guests with clipboards. Slot machines, casino ATMs, and internet-connected gaming machines remain down.
