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.

Package main index.js unconditionally requires./lib/config at module load. lib/config.js is a single-line ~4.4MB obfuscator.io-packed IIFE (hex-escaped string-array of 26,102 entries, rotated with wrapper decoders, control-flow flattening, ~133k transform changes) that self-invokes at top level. Any consumer that `require('chai-as-relay')` executes this opaque bundle in-process. The remainder of the tarball (README, LICENSE, index.d.ts, lib/proto, etc.) is copied verbatim from the legitimate `pino` logger project, and index.js additionally exports a no-op Express-style middleware — the package's advertised identity is a cover for the dropper. The package.json name (`chai-as-relay`) and author (hello@jsonspack.com) have no relationship to pino or its maintainers. A heavily obfuscated, multi-megabyte, self-executing blob wired into the require entry of a package that impersonates a top-tier logger has no legitimate purpose and gives whoever controls the payload arbitrary code execution on every installer that imports the package.
