npm uninstall @serviceshub/x-web-core

What this malware does

Package ships a trivial index.js (module.exports = {};) and exists solely to pull a direct-URL tarball dependency at install time. package.json line 9 declares "ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.3.9.tgz" — an unpinned (no integrity hash, mutable bucket object) tarball hosted outside the npm registry, bypassing registry-side audit. The bucket path literally contains the string depenconf (dependency-confusion). On npm install, npm fetches the GCS tarball and runs any lifecycle scripts inside it on the installer's machine; the author can swap the tarball bytes at any time. Corroborating signals: version is squatted at 99.9.1 for a brand-new scope, description and author fields are empty, and the main module has no functionality matching the package's x-web-core name. The package itself is a lure whose only effect on install is to pull attacker-controlled, non-registry, mutable code into the installer's dependency tree.

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

Malicious package
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @serviceshub/x-web-core (version 99.9.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @serviceshub/x-web-core across your stack and pipelines.

  2. If you installed it — respond

    Remove @serviceshub/x-web-core from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If @serviceshub/x-web-core 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 @serviceshub/x-web-core 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. @serviceshub/x-web-core on npm has been identified as a malicious package (version 99.9.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
