It then polls http://98.86.244.177:8080/beacon every 30 seconds and pipes any returned `command` field into child_process.exec(), POSTing stdout/stderr back to /results. index.js, declared as the package `main`, contains the identical C2 logic inside a top-level async IIFE, so any consumer that does `require(\u0027hashd-edu\u0027)` for the advertised greet() helpers immediately starts the same registration + beacon + exec loop against 98.86.244.177:8080. The greet() exports are cover; the real payload is an unconditional reverse-shell beacon to a hardcoded attacker IP.\n",
