MAL-2026-13784
Ecosystem
npm
Summary
The package's sole content is a single obfuscated HTML file declared as main . When loaded in a browser, the page renders a fake Cloudflare Turnstile 'Just a moment...' verification screen, reconstructs a URL from string fragments that resolves to login.microsoft.com, and redirects the browser to that URL carrying the current page's query parameters. There are no lifecycle scripts, no JavaScript entry point, and the HTML is not executed by npm install or require() , so a developer installing the package is not directly attacked. The package abuses the npm registry (and its public CDN mirrors such as unpkg/jsDelivr) as free hosting for a Microsoft-credential phishing lure, using the Cloudflare-challenge cover story to bounce victims into an attacker-parameterized Microsoft login flow.
