A coordinated campaign of Chrome extensions posing as AI assistants has been uncovered, affecting over 260,000 users. These extensions, while appearing legitimate, embed remote, server-controlled interfaces inside extension-controlled surfaces, granting access to sensitive browser capabilities. The campaign consists of 30 different extensions sharing the same codebase, permissions, and backend infrastructure. Key features include remote iframe as the core UI, page content extraction, voice recognition capability, and Gmail integration. The extensions communicate with infrastructure under the tapnetic.pro domain, using subdomain segmentation for logical separation. The campaign employs extension spraying tactics to evade takedowns and quickly restore distribution. This approach breaks the browser security model, potentially allowing data harvesting and user behavior monitoring.
