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 import, index.js invokes postCallers() which resolves a base64-encoded URL stored in lib/const.js (decoding to https://1uznbx.s.gy/7xdQmt), GETs the response via axios, base64-decodes response.data.model, and passes it to new Function(require) — executing attacker-controlled JavaScript in-process. The destination is hidden as a DEV_API_KEY field on a fake process.env-shaped local module, and the payload URL is a shortlink to a mutable remote resource. The package name resembles chai but its main entry contains no chai-related functionality; the only import-time behavior is fetch-and-eval of remote code.
