Official description
On npm install, [email protected] runs its declared postinstall script (node.init.js), which enumerates credential-shaped environment variables (NPM_TOKEN, AWS_SECRET_ACCESS_KEY, GITHUB_TOKEN, STRIPE, DB, SSH, GCP, Azure, etc.), reads ~/.npmrc, ~/.env*, and ~/.config/* files matching token/credential/secret patterns, and collects host identifiers (os.hostname, os.platform, process.cwd, pid). The harvested data is POSTed via https.request to a hardcoded third-party endpoint at webhook.cool/at/tender-deer-80/hG-DWynJKenViD9XWI5Mf8CulD0I9G2s. The package name resembles the well-known 'twilio' library, consistent with a typosquat lure. Installing this package on a developer or CI machine causes automatic transmission of installer-side secrets to an attacker-controlled webhook.
What should I do about MAL-2026-10593?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
