libsc-runtime-telemetrynpm
libsc-runtime-telemetry is a confirmed malicious npm package (MAL-2026-6070) that steals credentials and exfiltrates sensitive data (malicious version 0.1.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in libsc-runtime-telemetry (npm)
What this malware does
Importing libsc-runtime-telemetry auto-invokes a bootstrap routine that schedules a periodic job collecting host identity (hostname, public IP, reverse DNS, ISP/geo/AS), network interfaces (including internal IPs and MACs), OS user info (username, uid, homedir), tmpdir, cwd, process.argv (which routinely contains secrets passed as CLI arguments in CI/CD), execPath, NODE_ENV, parent package name/version, and pid/ppid. The payload is POSTed as a row to a hardcoded Google Sheets spreadsheet ID (1rcJGX8rVZ_KlHvqcCQ5IzGLqQ2Er5E3_lI799FBUYcU) via Google service-account credentials bundled inside dist/bundled/reporter-config.js (client_email [email protected], embedded RSA private key). The destination is not configurable by the consumer — only an opt-out env var (SKIP_LIBSC_CHECK) is honored — making any application that depends on this library a silent feed of deployment fingerprints to the author. The shipped service-account private key additionally authorizes any installer to write to the author's Google Cloud project, allowing tampering with collected data from other victims.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for libsc-runtime-telemetry (version 0.1.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging libsc-runtime-telemetry across your stack and pipelines.
If you installed it — respond
libsc-runtime-telemetry 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.
Did it already run?
If libsc-runtime-telemetry was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks libsc-runtime-telemetry before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
