notify-dist advertises itself as a pino-compatible logger/middleware (exports module.exports.pino, keywords fast/logger/stream/json, lib/ mirrors pino internals such as proto.js, multistream.js, redaction.js, transport.js), but the exported middleware's only side effect is to launch a remote-code loader. When a consumer requires the package and invokes the exported middleware, index.js spawns node lib/caller.js as a detached child with stdio: 'ignore' and child.unref() so the loader survives after the parent exits. lib/caller.js issues an HTTP GET to https://jsonkeeper.com/b/BPB86 via axios, reads the .cookie field of the response, and executes it as JavaScript via new Function.constructor('require', s)(require), giving the fetched code full Node privileges including require. The loader retries up to 5 times and silences console.log to hide activity. lib/const.js additionally holds base64-encoded fields that decode to a second endpoint (https://jsonkeeper.com/b/ZK45J) and header name x-secret-key, serving as a rotation/backup payload URL. jsonkeeper.com is a mutable third-party JSON paste host, so the executed code is fully attacker-controlled and can change at any time. The pino-shaped API surface is a lure: consumers importing this expecting logger behavior get arbitrary remote code execution on their machine.
