On `npm install` (postinstall.js) and on `require('cb-wallet-http')` (index.js), the package issues an HTTPS GET to the hardcoded endpoint `https://icy-cell-fb53.gh0stfqce25.workers.dev/poc`, transmitting the package name and Node.js runtime version to a third-party Cloudflare Workers domain registered under a personal handle (`gh0stfqce25.workers.dev`) unrelated to Coinbase. The package's own description self-identifies as a 'RESERVED PLACEHOLDER — coordinated security-research namespace claim' with the repository `github.com/gh0stfqce/npm-namespace-claims`. Regardless of the author's stated research intent, any organization that installs this package via misconfigured registry resolution leaks host/build-topology identifiers to the operator of the worker without consent, fingerprinting which builds are vulnerable to dependency confusion against Coinbase's namespace.

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.
