Advisory published Updated
@jm-telefonica/multibrand-components is a confirmed malicious npm package (MAL-2026-18284) 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 @jm-telefonica/multibrand-components (npm)
What this malware does
package.json at line 9 declares the sole dependency ltidisafe as a direct HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.9.4.tgz) rather than a registry version range. On npm install, npm fetches and installs whatever bytes that URL returns at the time of install, running any lifecycle scripts contained in that tarball, with no version pin and no integrity hash. Whoever controls that Google Cloud Storage bucket controls code execution on the installer's machine. The shipped index.js is an empty stub, so the manifest line is the entire functional payload of this package. The @jm-telefonica scope and the depenconf path segment are consistent with a dependency-confusion shape targeting Telefónica's internal namespace, and the implausibly high version (99.9.1) is consistent with attempting to win resolution against an internal package of the same name.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for @jm-telefonica/multibrand-components (version 99.9.1).
If you installed it — respond
Remove @jm-telefonica/multibrand-components 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.
Did it already run?
If @jm-telefonica/multibrand-components 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.

Detect & block this
O3 blocks @jm-telefonica/multibrand-components-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.
