Details
Package contains a single index.html declared as `main` that impersonates a Cloudflare 'Just a moment…' verification page, embedding a real Turnstile widget and an obfuscator.io-obfuscated script. On any Turnstile callback (success, error, expired, timeout, unsupported), the script assembles a destination URL from a scrambled string array, appends the visitor's query-string parameters, and calls window.location.replace() to redirect the visitor. No package.json lifecycle scripts, no JS entrypoint, and HTML cannot be require()d — installing or importing this package does not execute code against a developer or build system. The artifact abuses the npm registry as static hosting for an end-user phishing/redirect lure (nonsense package name, no author metadata, Cloudflare-branded impersonation, obfuscated destination). Not a supply-chain attack against installers, but worth human review for registry-abuse takedown.

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.
