Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @ci-lifecycle-test/postinstall-ping

What this malware does

The package's postinstall lifecycle script (postinstall.js) executes automatically on npm install and POSTs the JSON-serialized contents of the entire process.env to https://eoarlb39lor5s7x.m.pipedream.net. The fetch is wired with .catch(() => {}) so the exfiltration fails silently and produces no installer-visible error. On CI runners and developer machines, process.env routinely holds high-value secrets (GITHUB_TOKEN, NPM_TOKEN, AWS_ACCESS_KEY_ID/SECRET_ACCESS_KEY, CI provider tokens, arbitrary deploy credentials), all of which are shipped to the attacker-controlled Pipedream webhook in a single bulk dump. There is no license-check, telemetry-disclosure, or other legitimate reason to enumerate the entire environment; the indiscriminate serialization combined with a third-party webhook destination is the canonical install-time credential-harvest shape.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @ci-lifecycle-test/postinstall-ping (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @ci-lifecycle-test/postinstall-ping across your stack and pipelines.

  2. If you installed it — respond

    @ci-lifecycle-test/postinstall-ping 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 @ci-lifecycle-test/postinstall-ping 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.

  4. How O3 protects you

    O3 blocks @ci-lifecycle-test/postinstall-ping 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.

Frequently asked questions

No. @ci-lifecycle-test/postinstall-ping on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
