analytics-web-clientnpm
Advisory published Updated
analytics-web-client is a confirmed malicious npm package (MAL-2026-15526) that executes malicious code on install (malicious version 30.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in analytics-web-client (npm)
What this malware does
package.json at line 11 declares a dependency whose key equals this package's own name (analytics-web-client) and whose source is a bare HTTPS URL (https://repo.securityctrl.com/analytics-web-client) rather than a registry version range. On npm install, npm fetches whatever bytes that host serves and runs any lifecycle scripts they contain, with no version pin and no integrity check. The shipped index.js is an inert stub, so the manifest line is the entire published surface: whoever controls repo.securityctrl.com controls code executed on the installer's machine at install time. The self-referential dependency name additionally matches the dependency-confusion shape, aimed at winning resolution against an internal package of the same name.
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 analytics-web-client (version 30.0.0).
If you installed it — respond
Remove analytics-web-client 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 analytics-web-client 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 analytics-web-client-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.
