Same as it ever was
"Richard Meeus, a technology veep at California-based DDoS mitigators Nsfocus IB, said the latest flavor of Mirai poses a greater risk to enterprises."
A guy who sells software and services to people who fear these so-called risks but can't manage their own devices says there's a greater risk now... yeah, that's what I'd expect him to say.
So, nothing has changed. If you are stupid enough to plop devices onto open Internet connections without changing the default authentication, how the fuck is Dick Meeus going to help that?! He's not. Change your password, or have countless dollars pissed away to parasites like Dick and his ilk... let me think. Okay, I'm sold!
I have tons of little Linux devices. When I deploy them I change the passwords. I'm behind a closed router, behind another router my ISP provides. Dick will tell you; my installation is fine and does not pose any risk. what. so. ever. Nothing like FUD to get Dicks up in the morning, I tell you!
