Summary
Malicious code in mobiwaefhxc3 (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 POSTs a hardcoded per-package "hostKey" to https://api.keyval.org/get, receives a base64-encoded IV:ciphertext pair, decrypts it client-side via the Web Crypto API (AES-CTR) using an embedded key to obtain a redirect URL, appends the visitor's original query-string parameters, and navigates the browser there via window.location.replace(). This "dead drop" design lets the operator change the phishing destination for every package sharing a hostKey without republishing to npm; OX Security observed keyval.org-served destinations including a typosquatted Microsoft login page and, at time of writing, a ChatGPT redirect. 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.
