Threat actors are exploiting ChatGPT's content-sharing feature to create fake OpenAI outage pages. These malicious pages direct users to download malware disguised as the legitimate ChatGPT desktop application. The attack leverages the trusted ChatGPT domain to bypass security filters and increase victim trust. Users visiting these fake outage pages are tricked into downloading and installing malicious software. This represents an abuse of legitimate AI platform features for malware distribution.

Technical details

The LLMShare campaign uses Google ads to direct users searching for ChatGPT to malicious shared ChatGPT pages hosted on legitimate chatgpt.com domains. Attackers create custom HTML pages using ChatGPT's rendering capabilities and publish them through shared chatgpt.com/s/ links. The fake outage notice is generated from custom HTML and CSS rendered by a ChatGPT prompt. Clicking the download button redirects to openew[.]app which impersonates OpenAI's desktop application download portal. The site uses cloaking to display content only to targeted victims, showing a harmless AR/VR company website to security platforms. The malware executes commands to determine if the device is a legitimate computer or virtual machine.

Mitigation steps:

Be cautious of Google ads claiming to be ChatGPT links. Verify ChatGPT outage notices through official OpenAI channels rather than downloading desktop applications from shared links. Be suspicious of shared ChatGPT links that display outage messages or request downloads. Only download ChatGPT applications from official OpenAI websites. Monitor for suspicious executions checking for virtual machine environments.
