If anyone here owns a Qnap NAS, check it immediately. Freakin vulnerability is being exploited resulting in entire drive being encrypted. There are fixes if not too late but would suggest disconnecting from network. It's happening globally.

I got nailed. 15 yrs of pics & videos locked up tight. Thankfully I have an HDD that I back up to frequently and leave at my office. I haven't lost much but many many people used the Qnap as their backup and nothing else. Really, really bad stuff.
