fmt-date-lite @1.0.0

Summary

On npm install , the package's postinstall lifecycle script runs the id command and transmits the resulting user/group identity to a hardcoded bare-IP endpoint at http://155.190.124.243:6788/ over plain HTTP. Three fallback delivery mechanisms are used (node http.get, curl, wget) to maximize the chance of successful exfiltration across environments. This behavior has no legitimate connection to the package's advertised purpose (a date-formatting utility), and the benign-sounding name and date-fns-lite authorship function as cover for the install-time beacon — consistent with a lure/typosquat targeting the date-fns ecosystem. The id output reveals the installer's username, UID, GID, and group memberships, providing reconnaissance for follow-on attacks and confirming the callback for the operator.
