His happened about 2 weeks ago. This is not just the MGM Hotel in Vegas, but the entire MGM Resorts company. So Bellagio, NYNY, Mirage, Aria, Excalubur, etc...Not sure if Cosmo was affected as they had their own Identity company, but was sold to MGM recently.
But what I find interesting is it's been 2 weeks and not a peep on our local news, even though Vegas is the 9th Island. Since we go to Vegas so often, I have alternate information sources for NV/Vegas updates.
MGM properties, at first all slots were out of order, all check ins and check outs had to be done manually. Room keys didnt work (RFID/FOB type), their website was down, their app was down, credit card machines in stores and restaurants didn't work, ATM"s all down, etc..Some even had their elevators and AC's not work correctly. Then very slowly stuff is coming back, but not at normal like how the MGM stated on their Twitter. OPERATIONS ARE NOT BACK TO NORMAL.
Employee payroll was maintained, but some were short hours. Employees cannot log into the employee website to check their work schedules, PTO available, 401K balance, and their socials, birthdays and those who they had on the system like spouses and childrens socials and birthdays have been compromised.
About a week after this, some slots were working, but no one could cash out via a cash out ticket. They had to wait for a handpay. So you put in $100 and lose $50 and want to switch to another machine. You had to wait about an hour until a slot attendant came by and gave you your money back from the machine. Check in times at the Excalibur were like up to 7 hours and their line was out the door.
Today, more slots are working, but instead of some saying "out of order", it just wont accept any money. Guess MGM thought this was a good idea to give the image that they're back to normal. Hand payments have been reduced to about 15 mins, but you still cannot cashout tickets in certain machines/locations. TBH, I wouldn't play a slot machine because any big win might be voided due to the hack excuse the casino might use.
Vegas media reported more of this, but it's people posting vids of what's not working is where most of the information comes from and from the workers.
This happened to the Ceasars company in July and they paid off the hackers like $15 million to restore everything. This wasn't just the Ceasars Hotel, but the company. So Harrahs Hotel, Planet Hollywood, etc...
It doesn't look like MGM will pay off tfhe hackers.
Other hotels outside of the MGM system are fine so far.
