As you well know !
I was on a MSP team that remediated .RYUK for a very large nursing home chain. We were unable to determine "patient zero" or how it got on the network, but it used the company VPN to propagate to every device connected to the domain and seemed all automated. The big mistake they made was allowing devices to stay connected to the vpn indefinently, no timeout....... It encrypted the drive and they wanted millions, not sure how much it was all rumors but I heard 10 mill, 14 mill, and a couple others.
We remediated by reformatting all affected devices, it was about 75ish%. It might have been cheaper to pay because we had to send techs out to every site and took like 6 to 8 months to get through it suuuuuucked and we had over 1000 phone calls a day for a couple weeks, the average was like 400 a day..
Finally, I know that camDown is a highly advanced, specialized webcam blocker and disabler with the best in class protection from variety of on-line threats and I know your father would say the same!
