Malicious Chrome Extension “ChatGPT Ad Blocker” Targets Users, Steals Conversations

This report describes a malicious Chrome extension named “ChatGPT Ad Blocker” that masquerades as an ad-blocker while capturing users' ChatGPT prompts, conversation history, and metadata, packaging them into a page_dump.html and exfiltrating them to a private Discord channel via a hardcoded webhook; investigators link the extension to a reactivated GitHub developer handle and warn that associated AI services may be compromised, recommending users avoid third-party AI add-ons and scrutinize extension permissions.
