I actually initially thought this sort of malware was transferred through communicating through the actual Spidey Bot on Discord, but I'm glad that's not the case and I assume it spreads via normal vectors other viruses typically take with Windows. Still checked my Discord files either way and they seem to be fine, but if you don't have time to read the entire article, here's how you can know if you've been infected or not:
To check the %AppData%\Discord\[version]\modules\discord_modules\index.js simply open it in Notepad and it should only contain the single line of "module.exports = require('./discord_modules.node');" as shown below.
For the %AppData%\Discord\[version]\modules\discord_desktop_core\index.js file, it should only contain the "module.exports = require('./core.asar');" string as shown below.
[version] is the numbered file inside Discord, something like 0.0.305 or something of the sort.
