Cybersecurity researchers are cautioning users against installing certain browser extensions that claim to improve ChatGPT functionality, warning that some of these tools are being used to steal sensitive data and gain unauthorized access to user accounts.
These extensions, primarily found on the Chrome Web Store, present themselves as productivity boosters designed to help users work faster with AI tools. However, recent analysis suggests that a group of these extensions was intentionally created to exploit users rather than assist them.
Researchers identified at least 16 extensions that appear to be connected to a single coordinated operation. Although listed under different names, the extensions share nearly identical technical foundations, visual designs, publishing timelines, and backend infrastructure. This consistency indicates a deliberate campaign rather than isolated security oversights.
As AI-powered browser tools become more common, attackers are increasingly leveraging their popularity. Many malicious extensions imitate legitimate services by using professional branding and familiar descriptions to appear trustworthy. Because these tools are designed to interact deeply with web-based AI platforms, they often request extensive permissions, which exponentially increases the potential impact of abuse.
Unlike conventional malware, these extensions do not install harmful software on a user’s device. Instead, they take advantage of how browser-based authentication works. To operate as advertised, the exte
