Can someone please explain to Grandpa Erinaceus (me), what I should do in response to this? Is it just browsers and VPNs or other things as well? Maybe as in like 1) Don’t panic, 2) Update everything, 3) etc

Um . . . not familiar with this . . . ? Sounds scary maybe

EDIT: Ah, I see. Scary acronym. I need to self-criticize now because of a bourgeois and improper reaction to SLUM. Well, live and learn . . . 🤦‍♂️

I’ve got a VPN and am using Mullvad Browser, any issues there? It keeps asking me how damn high the stupid fluffy little animals are jumping, over and over again . . .
