When scanners miss the attack: how Cloudflare Client-Side Security protects storefronts
Cloudflare's Page Shield ML uncovered four malicious JavaScript campaigns on storefronts, including affiliate fraud and a remote-backdoor script, that VirusTotal and URLScan missed.
Cloudflare's Page Shield ML detected four client-side JavaScript operations (eight payloads) in live traffic on online storefronts, enabling affiliate commission hijacking, clickless affiliate theft via hidden iframes, user tracking with a remote-code backdoor, and cloaking of paid mobile visitors. Seven of the eight payloads were absent from VirusTotal and URLScan returned no malicious verdict for any, including a Lnkr-family payload indexed unclassified for roughly 2.5 years. Detection relies on a graph neural network over JavaScript syntax trees, an LLM second opinion on Workers AI, and a frontier-model ensemble voting across benign, magecart, other malware, and cryptomining labels.

Weedhack Malware Spreads via Fake Minecraft Clients and SEO Poisoning
McAfee Labs reports Weedhack malware spread via spoofed Minecraft client websites using SEO poisoning, with over 6,300 blocked access attempts.
McAfee Labs found multiple lookalike websites impersonating legitimate Minecraft clients (Glazed, Radium, Meteor, Nova, Xenon) still distributing Weedhack, a multi-stage malware whose JAR payloads collect system information, add Microsoft Defender exclusions, and steal sensitive data. Distribution relies on SEO poisoning to outrank official sources, plus Discord, MediaFire, GitHub, and Minecraft hosting sites; nearly half of malicious URLs were Discord links. One fake site was built with the AI website builder Lovable, and McAfee blocked more than 6,300 access attempts to malicious sites.
