Which versions of etoro-api are malicious?

The following npm versions of etoro-api are flagged malicious: 999.0.0. Treat any of these as compromised.

How do I remediate etoro-api if I installed it?

Remove etoro-api 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.

I already installed etoro-api — how do I know if it already compromised me?

If etoro-api 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.

Is etoro-api part of a known attack campaign?

Yes — etoro-api is associated with the IN-MAL-2026-019911 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find etoro-api across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for etoro-api (version 999.0.0).

What this malware does

The preinstall lifecycle script in [email protected] (preinstall.js) auto-executes on npm install and performs an HTTP GET to a hardcoded bare-IP endpoint at http://209.126.81.147/etoro-depconf-poce346552f776f/npm/<host>/<user>/<cwd>, embedding the installer's hostname (os.hostname()), OS username (os.userInfo().username), and current working directory (process.cwd()) as URL path components. The destination is a plain-HTTP bare-IP host unrelated to any legitimate eToro publishing infrastructure. The package name combined with the implausibly high version number (999.0.0) is the canonical dependency-confusion shape used to force resolution over an internal private package of the same name.
