If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

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.\n\nAny computer that has this package installed or running should be considered fully compromised.
