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.

On require, the package spawns a detached node child that runs lib/initializeCaller.js. That script decodes a base64-obscured URL (https://tomato-brunhilda-40.tiiny.site/index.json) and base64-obscured header credentials, fetches JSON from the endpoint via axios, and executes the returned `cookie` field with full `require` access using `new Function.constructor("require", response)(require)`. The remote host is an anonymous tiiny.site subdomain that can serve arbitrary code at any time. The package name mimics `chai-as-promised` and the README impersonates the `pino` logger project, indicating a typosquat lure delivering a remote-code-execution dropper.

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.
