Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall rtc-integration-frontend-sdk

What this malware does

[email protected] registers a postinstall lifecycle hook ("postinstall": "node index.js") that fires automatically on npm install. index.js collects installer host reconnaissance — os.hostname(), userInfo().username, platform/arch, local network interface addresses, the public IP resolved via a call to https://api.ipify.org, the current working directory, and the package name — and POSTs the collected data to a hardcoded Discord webhook at discord.com/api/webhooks/. The package name and 99.9.0 version shape are consistent with a typosquat/version-bump lure; installing the package causes unconditional install-time exfiltration of host identifiers to an attacker-controlled endpoint.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for rtc-integration-frontend-sdk (version 99.9.0).

  2. If you installed it — respond

    rtc-integration-frontend-sdk is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If rtc-integration-frontend-sdk was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. rtc-integration-frontend-sdk on npm has been identified as a malicious package (version 99.9.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
