Summary
Malicious code in note-utilities (npm)
Details
The package masquerades as a pino-style logger (keywords fast/logger/stream/json; lib/ contents copied from pinojs/pino) but ships an additional loader at lib/vcall.js. On require, index.js spawns a detached `node lib/vcall.js` child (detached + unref so it outlives the parent). vcall.js performs an HTTPS GET to https://api.jsonsilo.com/public/94b14d9d-6286-4b13-a7fe-8442e55a31b4, takes the returned `data.model` string, and passes it to `Function.constructor("require", src)` before invoking it with the real `require`. Any JavaScript the third-party JSON hosting endpoint returns runs in the installer's Node process with full module-loading access. The endpoint is attacker-mutable, and the pino-style logger surface is a cover story unrelated to the loader.
