Summary

Hide ▲

WordPress sites are being exploited to inject malicious JavaScript that redirects users to phishing pages. The attacks use a theme-related file to load a dynamic payload from a remote server, which includes a JavaScript file and a hidden iframe mimicking legitimate Cloudflare assets. The domain involved is part of a traffic distribution system (TDS) known as Kongtuke. The campaign highlights the need for securing WordPress sites and keeping software up-to-date. Additionally, a new phishing kit named IUAM ClickFix Generator allows attackers to create customizable phishing pages mimicking browser verification challenges. This kit has been used to deploy information stealers like DeerStealer and Odyssey Stealer. The emergence of such tools lowers the barrier to entry for cybercriminals, enabling sophisticated, multi-platform attacks. A new ClickFix campaign employs cache smuggling to evade detection, using the browser's cache to store malicious data without downloading files or communicating with the internet. The attack masquerades as a Fortinet VPN Compliance Checker, executing an obfuscated payload via a PowerShell script.
