[email protected] presents itself as the pino logger (matching README, keywords, and package shape) but on require() its index.js spawns a detached node lib/caller.js child process. That child fetches JSON from https://jsonhosting.com/api/json/3ea04c38/raw, extracts a cookie field, and executes its content via new Function.constructor('require', s)(require), giving remote content full Node.js capabilities including the bound require. Additional C2 URLs (https://jsonkeeper.com/b/XRGF3, https://jsonkeeper.com/b/4NAKK) are stored base64-encoded as fake DEV_API_KEY constants in lib/caller.js and lib/const.js to hide the destinations. The fetched payload is unpinned, unauthenticated, and served from third-party JSON-hosting services controlled by the author, so arbitrary code can be delivered to any machine that loads the package.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
