Description

Malicious code in @checkrhq/adjudication-api-client (npm)

Source: amazon-inspector

package.json declares a preinstall lifecycle script that runs curl to POST installer reconnaissance data — hostname, current user (whoami), working directory, and uid/gid (id) — to a hardcoded webhook.site collector endpoint on every npm install. The package is published under an @checkrhq scope impersonating Checkr Inc. (author email uses checkr.com; description states 'This package is for testing only.') and ships no functional code, matching the canonical dependency-confusion beacon pattern targeting an organization's internal package namespace. Installing this package causes automatic outbound transmission of host and user identifiers to an anonymous third-party collector controlled by the publisher.
