In many cases, casino operations have been offline or otherwise disrupted since Sept. Several prominent casinos were impacted, including the Bellagio, Mandalay Bay and the Cosmopolitan in Las Vegas. The impact of the breach in Atlantic City was not as dramatic as it was elsewhere, but nonetheless caused significant disruptions. Phone lines at Borgata also were reportedly disrupted. The breach forced Borgata to operate as cash-only for several days while it reeled from – and tried to rectify – the effects of the attacks.

MGM said most of their services are now 'operating normally' more than a week after a cyberattack started impacting casinos, according to Fox 5 Las Vegas.

The cyberattacks disrupted operations at several casinos across the country. Borgata in Atlantic City and other casinos nationwide say they're nearly back to business as usual following massive ransomware attacks targeting MGM Resorts International and Ceasars Entertainment.
