etoro-aggregatornpm
Advisory published Updated
etoro-aggregator is a confirmed malicious npm package (MAL-2026-16111) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.2, 999.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in etoro-aggregator (npm)
What this malware does
The package's preinstall.js lifecycle script executes automatically on npm install and performs reconnaissance on the installer host. It collects hostname, username, current working directory, platform, and the output of OS commands including whoami /all, ipconfig /all / ifconfig, tasklist / ps aux, directory listings of /, C:\, and the user's home, and a dump of environment variables. The collected data is transmitted via HTTP GET and POST to the hardcoded bare IP endpoint http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/v4/.... The package's declared main is an empty stub and its description ("Internal service client library") combined with the implausibly high version number 99.0.2 is consistent with a dependency-confusion attack targeting an internal etoro-aggregator name. The manifest plus the preinstall script constitute the entire payload; installing the package leaks installer host identity, network configuration, filesystem structure, and environment variables (which routinely contain credentials and tokens) to an attacker-controlled endpoint.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for etoro-aggregator (3 malicious versions).
If you installed it — respond
etoro-aggregator is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If etoro-aggregator 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-aggregator-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
