LAS VEGAS (KTNV) -- Two Las Vegas casinos appear to be recovering from a mysterious, days-long computer outage which left casino floors and slot machine chairs empty.

"When it comes to cyber security, it's not if, it's a when and how bad," said Garvin Bushell, president of The Learning Center Las Vegas.
"No matter what you do, the hackers just have to be right one time and as an IT professional, I have to be right every single day and all those attacks are happening on a daily basis," said Bushell.
13 Investigates has asked ownership of the Four Queens and Binion's Casino repeatedly about the apparent computer problem, but a request for comment was not returned.
Bushell says in his experience the length out the outage indicates this was not a simple problem.
"Ransomware is out there and for them to be down from Wednesday to [Monday] it kind of raises from flags," said Bushell.
13 Investigates inquired with the Nevada Gaming Control Board about any active or on-going investigations about the source of the malfunction but a request for comment was not returned after business hours Monday.
In January, the City of Las Vegas announced it fell victim to a "cyber compromise" and revealed they experience breach attempts 279,000 times per month on average.
