ring-device-settings-librarynpm
Advisory published Updated
ring-device-settings-library is a confirmed malicious npm package (MAL-2026-15520) that executes malicious code on install (malicious versions 30.0.0, 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in ring-device-settings-library (npm)
What this malware does
package.json declares a dependency whose key equals the package's own name (ring-device-settings-library) and whose value is a raw HTTPS URL pointing at an off-registry host: https://repo.securityctrl.com/ring-device-settings-library. On npm install, npm resolves that URL rather than a registry version range and installs whatever bytes the host returns, running any lifecycle scripts contained in the fetched artifact. There is no version pin, no integrity hash, and no signature check, and the host is unrelated to any npm registry. The shipped package contents are otherwise an inert placeholder, so the manifest line is the entire installed surface: whoever controls repo.securityctrl.com controls the code that executes on the installer's machine on every install. The self-referential dependency name, combined with the implausibly high version (45.0.0), is also a dependency-confusion shape that can win resolution against an internally-named package.
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 ring-device-settings-library (2 malicious versions).
If you installed it — respond
Remove ring-device-settings-library 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 ring-device-settings-library 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 ring-device-settings-library-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.
