{"id":"MAL-2026-15606","summary":"Malicious code in m3fdfocdoewn (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.\n\n---\n_-= Per source details.
