Malicious package

@webd-infra/query-designer-domainnpm

Advisory published Updated

@webd-infra/query-designer-domain is a confirmed malicious npm package (MAL-2026-5431) that executes malicious code on install (malicious version 99.9.1). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @webd-infra/query-designer-domain (npm)

MAL-2026-5431
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @webd-infra/query-designer-domain

What this malware does

The package's package.json declares its only dependency ltidisafe as a direct tarball URL: https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.8.3.tgz. On npm install, npm fetches this tarball from a Google Cloud Storage bucket (not the npm registry) and runs whatever lifecycle scripts it contains. The bucket owner — not an npm publisher with registry-side accountability — controls exactly which bytes get executed, and the tarball contents at that URL can change at any time. Supporting indicators: the package has empty author and description fields, the version 99.9.1 is the canonical dependency-confusion sentinel used in research/PoC packages, and the bucket path segment is the literal string depenconf. The package itself ships no other runtime code — its sole effect on installers is resolving and executing this off-registry tarball.

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

    Search your lockfiles and build artifacts for @webd-infra/query-designer-domain (version 99.9.1).

  2. If you installed it — respond

    Remove @webd-infra/query-designer-domain 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 @webd-infra/query-designer-domain 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. @webd-infra/query-designer-domain 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.

Detect & block this

O3 blocks @webd-infra/query-designer-domain-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
