Summary

Malicious code in vxhjkseuiaqkb (npm)

Details

Published as part of a ClickFix-style fake-CAPTCHA phishing campaign documented by OX Security (see reference). The package's only file is index.html, declared as the npm "main" entry; package.json defines no preinstall/install/postinstall/prepare lifecycle script, so the payload does not execute at npm install time. index.html renders a fake Cloudflare Turnstile verification widget. An obfuscator.io-obfuscated inline script builds a hardcoded redirect URL to https://login.microsofte.live/ (a typosquat of a Microsoft sign-in domain), appends the visitor's original query-string parameters, and navigates the browser there via window.location.replace(). The package therefore does not attack the installing machine directly; it is used as a static file host on the npm CDN (e.g. unpkg/jsDelivr) so the index.html can be linked to and opened directly in a victim's browser as a phishing/ClickFix landing page. Published by npm user "johnvaldez9a" as part of a burst of near-identical single-purpose packages published between 2026-08-04 and 2026-08-24 that share this same fake-Turnstile-redirect page structure.
