Threat actors are abusing ChatGPT’s content-sharing feature to display fake OpenAI outage pages that direct users to download malware disguised as the ChatGPT desktop application.

The “LLMShare” campaign, discovered by Push Security, uses Google ads to direct users searching for ChatGPT to a malicious shared ChatGPT page hosted on chatgpt.com, allowing the attack to be delivered through a legitimate OpenAI domain.

Users who click the advertisement are taken to a legitimate ChatGPT shared page, but instead of seeing a chat conversation, they are presented with a rendered outage notice claiming the web version is unavailable and that they should download the desktop application instead.
