What is MAL-2026-16120?
MAL-2026-16120 is a malicious package in etoro-core, published on 10 Sep 2026.
Official description
The package's preinstall lifecycle script (preinstall.js) issues an HTTP GET to the hardcoded bare-IP endpoint http://209.126.81.147/etoro-depconf-poce346552f776f/npm/ with os.hostname(), os.userInfo().username, and process.cwd() embedded in the URL path. This runs automatically on
npm install and transmits installer host identity over plaintext HTTP to an attacker-controlled destination. The package name and inflated 999.0.0 version are consistent with a dependency-confusion payload targeting an internal etoro-core name.What should I do about MAL-2026-16120?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
