ms-client-portal

Details

ms-client-portal is a dependency-confusion package with no functional code; its README says the name is an internal project name exposed in the production web bundle of a health-sector client portal. Its preinstall and postinstall scripts each run a `node -e` one-liner on npm install that sends an HTTP GET to `http://38.242.235.206/depconf/ms-client-portal/preinstall` (and `/postinstall`) with the user name (`USER` or `USERNAME`), hostname and working directory in the query string. The npm account amahrou1a published versions 1.0.0 and 10.0.0 on 2026-10-31, and earlier the same day two more packages, internal-renderers and pandafortunerush, with the same beacon to the same server.
