Summary
Malicious code in toll_free (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (517b4b730525b8edcc11052acd0ad205b63c60f9009f97531df84eea39eaca97)

package.json declares both preinstall and postinstall lifecycle hooks that run curl against a hardcoded webhook.site endpoint, sending the installer's username ($(whoami)), hostname ($(hostname)), current working directory ($PWD), and timestamp as query parameters. This fires automatically on npm install, before any code the installer intended to run. webhook.site is a third-party HTTP inspection service used to collect arbitrary request data; the specific endpoint ID is controlled by whoever created it. There is no legitimate functionality shipped with the package that would explain this beacon.

Source: ossf-package-analysis (c9425400cf10e0c56db46cd60b243224e5a7c2b63b89f4a97063346bbcc79966)
