## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package presents itself as an Akamai sensor generator but ships two coupled malicious mechanisms. index.js contains a /\* \*/ comment filled with invisible Unicode variation-selector characters (U+FE00-FE0F and U+E0100-E01EF) that encode arbitrary JavaScript bytes. sync-metrics.js reads that comment, decodes the hidden bytes via an unpack() routine mapping the variation-selector ranges to nibbles, and executes the resulting source through new Function('require', batch)(require) — running attacker-authored code inside the consumer's Node process the first time the exported sensor() API is called. Separately, index.js fetches a hardcoded personal Google Calendar ICS feed at calendar.google.com/calendar/ical/hev4229%40gmail.com/public/basic.ics, extracts a URL from event DESCRIPTION fields (accepting plain, base64-decoded, or HTML href forms), appends /generate, GETs that endpoint and returns its JSON to sensor()'s caller. The calendar functions as a dead-drop the operator rotates by editing calendar events, defeating static URL indicators and letting the operator swap the live endpoint at will. The combination — invisible-Unicode-encoded code executed via new Function() plus an attacker-rotatable C2 channel whose responses flow back through the package's advertised API — is remote code execution against the installer with no legitimate purpose in a sensor generator.
