Linux devices are under attack by a never-before-seen worm

This is a most excellent place for technology news and articles.
Hard to tell at a glance.
The telnet vulnerability allows it to infect some older IoT devices (such as CCTV cameras) or if you are using an older router where telnet is enabled (or may be enabled by default). Most modern devices don't use that method anymore due to security concerns.
The SSH vulnerability can affect a lot more devices. So if you have a Raspberry Pi on your network with a default account/password or a weak password then it can infect that and spread to other devices on your local network. Or maybe a cheap IoT device that has weak security... same problem.
A concern for you is if you have some other device on your network that was vulnerable, because then that device can serve as a point for the worm to jump to your other devices (if they also use default passwords or weak passwords).
Another big question to ask is whether you have UPnP enabled on your router.
Either way I would make sure that you have strong passwords, change the default username, etc, on all of your devices.
