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.json declares the sole dependency `packet-table-thread-stream` as a direct tarball URL to a non-npm host (`https://artifacts.yosiroute.com/npm/packet-table-thread-stream`), with no version pin and no integrity hash. The shrinkwrap marks that dependency `hasInstallScript: true`, so on `npm install` npm fetches opaque code from `artifacts.yosiroute.com` and executes its lifecycle scripts on the installer's machine, bypassing npm registry scanning. The wrapper package itself is a disposable shim: index.js is trivial (only re-exports name/version), and package.json metadata is placeholder (`author: Package Registry`, `description: Generated package`, `repo: github.com/example/...`). The package's only functional effect on install is pulling attacker-controlled code from a non-registry host into the installer's dependency tree and running its install scripts.
