## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's only shipped content is a single HTML file that mimics a Cloudflare 'Just a moment...' security challenge. The inline script is obfuscated with an obfuscator.io-style shuffled string-array + hex identifier decoder and anti-debug console overrides. After a 1-second delay it assembles a hostname from split literals ('gin.microc' + 'loud.homes' → login.microcloud.homes), forwards the current URL's query string, and calls window.location.replace to redirect the browser to that external host. package.json declares no lifecycle scripts and \`main\` points at HTML rather than a loadable JS module, so installing or requiring the package does not directly execute the payload against a developer's machine — the harm is directed at end users who load the hosted HTML, using the npm registry as a CDN for a phishing kit. This is registry/namespace abuse rather than a direct installer-side attack; recommend human review to confirm and to coordinate takedown with the registry.

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.
