Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall apple-internal-pki-utils

What this malware does

Malicious npm package published by threat actor "raya4321" as part of a coordinated typosquatting campaign impersonating Apple internal infrastructure services (authentication, PKI, telemetry, CloudKit, and cloud infrastructure). All packages in this campaign execute credential-theft payloads during npm installation via preinstall or postinstall lifecycle hooks.

Trigger: postinstall. Exfiltrates hostname and filtered environment variables matching APPLE, AWS, GIT, or SECRET key patterns, base64-encoded, to a requestcatcher.com endpoint constructed from the $CATCHER_NAME environment variable (/apple_leak path).

The package apple-internal-pki-utils was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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 apple-internal-pki-utils (version 1.0.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging apple-internal-pki-utils across your stack and pipelines.

  2. If you installed it — respond

    apple-internal-pki-utils 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 apple-internal-pki-utils 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 apple-internal-pki-utils 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. apple-internal-pki-utils on npm has been identified as a malicious package (version 1.0.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
