etoro-chartsnpm
Advisory published Updated
etoro-charts is a confirmed malicious npm package (MAL-2026-16118) that opens a backdoor for remote access (malicious versions 99.0.0, 999.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in etoro-charts (npm)
What this malware does
On npm install, preinstall.js runs automatically and sends the installer's hostname, username, platform, and current working directory via HTTP GET to http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/npm/v2/<host>/<user>/<platform>/<cwd>, then executes whoami; id; hostname -f (or whoami /all on Windows) via child_process and POSTs the command output to the same hardcoded bare-IP endpoint over plain HTTP. The package.json advertises the package as an Internal service client library at version 99.0.0 with no real functional code beyond the preinstall hook, and the beacon path segment etoro-nuget-verify... targets an internal eToro namespace, matching the dependency-confusion recon pattern.

Search your lockfiles and build artifacts for etoro-charts (2 malicious versions).
If you installed it — respond
etoro-charts establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If etoro-charts 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 etoro-charts-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
