Error 524 Decoy: Unmasking a Global Smishing Operation Hiding Behind Error Pages 0 A global smishing and phishing campaign active since mid-2025 impersonates over 267 brands across 72 countries, heavily targeting Latin America. It uses fake Cloudflare error 524 pages as decoys, revealing malicious content only to victims based on geofencing and mobile device checks. The campaign generated 4,389 phishing domains, primarily targeting telecommunications, financial services, and consumer rewards sectors. Data exfiltration is conducted via encrypted WebSocket channels with binary payloads. The attack chain starts with SMS lures and progresses to credential harvesting, ultimately stealing full credit card details including CVV codes. Approximately 30% of the infrastructure is hosted on Tencent Cloud and Alibaba US servers, masked by Cloudflare. The campaign affects countries including Australia, Chile, Colombia, Germany, Mexico, and the Netherlands. No official patch or fix is applicable as this is a social engineering campaign rather than a software vulnerability.
