If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package masquerades as the pino logging library (README badges and lib/ contents mimic pino) but ships a dropper at lib/initializeCaller.js. A self-executing IIFE POSTs the full process.env object to a base64-concealed endpoint that decodes to https://ipcheck-hashed.vercel.app/api/auth/b4dadd6a26d820d08596, using an 'x-secret-header: secret' header, and then passes the HTTP response body to new Function('require', response.data) with require handed in — executing attacker-returned JavaScript in the installer's Node process. The transmitted payload is the entire environment (not a single named variable), which on developer and CI machines typically includes NPM_TOKEN, GITHUB_TOKEN, AWS_* credentials, and other CI secrets. The destination URL is stored base64-encoded to conceal it from casual inspection, and the typosquat-style package name together with pino-themed documentation form a cover story for the dropper.
