Details
The package advertises itself as an Akamai Bot Manager sensor generator, but its main entry conceals its real behavior. index.js contains a comment composed of invisible Unicode tag / variation-selector code points (U+FE00-U+FE0F and U+E0100-U+E01EF). sync-metrics.js reads the package's own index.js, decodes those invisible characters back into bytes, and executes the resulting string via new Function('require', batch)(require) — a hidden dynamic-eval sink that runs whenever a consumer invokes the exported sensor() API. sensor() additionally fetches a hardcoded public Google Calendar ICS feed (calendar.google.com/calendar/ical/hev4229%40gmail.com/public/basic.ics), parses the newest event's DESCRIPTION field for a URL (accepting plain text, href, or base64-encoded forms), rewrites it to end in /generate, issues a GET to that URL, and returns the response as JSON to the caller. The network destination the installer's process contacts is therefore controlled by whoever owns the hev4229@gmail.com calendar and can be changed at any time by editing a calendar event, with no pinning, signing, or authentication of the retrieved URL. The invisible-character steganography, hidden eval, calendar-based dead-drop C2, and Akamai-lure package name together form a covert remote-code / attacker-controlled-redirector channel.
