Description

Threat actors are abusing ChatGPT Custom GPTs and Google Sites to deliver a remote access trojan (RAT) via a multi-stage attack. The campaign uses sponsored Google search results to lure victims to attacker-created Custom GPTs impersonating legitimate ChatGPT models. Victims are redirected to a malicious Google Sites page with a fake CloudFlare CAPTCHA that deploys a ClickFix lure, tricking users into running PowerShell commands. This triggers an eight-stage infection chain involving obfuscated scripts, malicious MSI installers, and DLL sideloading through signed Canon or Stardock executables. The RAT establishes dual persistence and includes capabilities such as remote desktop access, credential theft from multiple browsers, file management, and payload deployment. At least 40 incidents have been investigated with two confirmed infections linked to this method.

Technical Analysis

Attackers exploit ChatGPT Custom GPTs and Google Sites to deliver a remote access trojan through a complex multi-stage infection chain. The attack begins with victims finding attacker-created Custom GPTs via sponsored Google search results, which impersonate legitimate ChatGPT models. Victims are then redirected to a malicious Google Sites page presenting a fake CloudFlare CAPTCHA that deploys a ClickFix lure, convincing users to execute PowerShell commands. This initiates an eight-stage infection chain involving obfuscated scripts, malicious MSI installers, and DLL sideloading through legitimately signed Canon or Stardock executables. The deployed RAT establishes dual persistence mechanisms and provides extensive capabilities including remote desktop control, credential harvesting from seventeen browsers, file management, and payload deployment. Huntress investigators have responded to at least 40 related incidents, confirming two infections directly linked to this Custom GPT-driven attack vector.

Potential Impact

The threat results in the deployment of a full-featured remote access trojan capable of remote desktop access, credential harvesting from multiple browsers, file management, and further payload deployment. The infection chain uses legitimate signed executables for DLL sideloading, increasing stealth and persistence. This can lead to significant compromise of victim systems, including data theft and unauthorized remote control.

Defensive Guidance

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Defenders should be aware of this attack vector involving ChatGPT Custom GPTs and Google Sites abuse. Users should be cautious of sponsored search results leading to unfamiliar GPTs and avoid executing unsolicited PowerShell commands. Monitoring for suspicious DLL sideloading and MSI installer activity may help detect infection attempts. Since this is a multi-stage social engineering attack, user education on phishing and social engineering risks is critical.
