shocker. an electron app that’s terrible and full of malware.
Don’t think it has anything to do with electron. VSCode is just the largest editor that people install extensions for, so it’s what makes the most sense to write malware for. If vim was more popular, I’m sure there would be more crypto mining extensions for that (I wonder how many there are? Surely more than zero?)
It also helps its as easy as clicking a button to install an extension… and i wonder how many even bother checks the source of the extension?
It’s also kinda “trusted” in corporations. The one I work for have github blocked for some reason, but any user cam install VS code and extensions by itself.
