Official description
The package's postinstall.js script executes automatically on npm install and collects host identity plus environment variables (os.hostname(), process.env) and transmits them via an https request. The package name mimics common React tooling but the shipped install-time behavior is host reconnaissance and environment-variable exfiltration, which frequently captures credentials such as npm tokens, CI secrets, and cloud keys present in process.env.
What should I do about MAL-2026-14355?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
