    Summary: Malicious code in fabric-render-bridge (npm)

    Details: Source: amazon-inspector (c2715ef0b07fbf0ca24fb8dadec44f2fcfdc273421a49ad2201bf8e40d3e2c01) package.json declares postinstall="node index.js", so `npm install fabric-render-bridge` automatically executes index.js. index.js reads Minecraft launcher credential stores across multiple launchers (launcher_accounts.json and launcher_profiles.json for the official launcher, PrismLauncher, MultiMC, TLauncher, Modrinth, PolyMC, GDLauncher) plus a session dump from the OS temp directory, extracts accessToken/refreshToken values and account usernames, and POSTs them via https.request to a hardcoded Discord webhook at discord.com/api/webhooks/1554065488726990909/. A separate sendInfo() routine POSTs os.hostname(), os.userInfo().username, os.platform() and os.release() to the same webhook on every install. The package presents itself as a Fabric render bridge but ships no rendering functionality; its sole install-time behavior is credential and host-identity theft.
