Key points
- Extension previously banned for stealing AI chat data was reinstated to Chrome Web Store
- Malicious extension amassed over 300,000 installs with 4.6-star rating before removal
- Researchers confirm reinstated extension resumed unauthorized AI conversation exfiltration
- Recurrence indicates insufficient post-ban enforcement in Chrome extension review process
- SecurityWeek reported the return and continued malicious activity of the extension
The story
A Chrome extension previously removed by Google for exfiltrating AI chat data has returned to the official store and resumed malicious activities, according to SecurityWeek. The extension had accumulated over 300,000 installs and a 4.6-star rating before its initial ban for unauthorized data collection. Researchers report the reinstated version continues stealing sensitive conversations from generative AI platforms despite prior enforcement action. This recurrence suggests inadequate post-removal monitoring within the Chrome Web Store ecosystem. The incident highlights persistent vulnerabilities in browser extension security reviews that allow bad actors to evade permanent bans. Users who reinstalled or newly downloaded the extension after its return are potentially exposed to ongoing data theft. Google has not yet commented on the specific reinstatement mechanism or new mitigation measures. Security experts warn this pattern undermines trust in official distribution channels for AI-integrated tools.
