ClickFix moves into the browser: Cryptocurrency theft with Google-hosted C2
A ClickFix variant hides its C2 inside Google Sheets via the Visualization API, injecting obfuscated JavaScript into browser sessions to steal cryptocurrency—posing a detection blind spot for proxy-based defences.
Summary written by editorial AI · Source link below
Cisco Talos is tracking a cryptocurrency-stealing campaign that abuses the Google Visualization API for command and control (C2), retrieving obfuscated JavaScript from a publicly published Google Sheets document and injecting it into the victim's browser session.
Editorial Analysis
Embedding C2 in Google's own APIs makes malicious traffic indistinguishable from normal SaaS usage, pushing enterprises toward browser-level telemetry for detection.
Evaluate browser isolation or in-browser threat detection tools that can identify injected JavaScript regardless of the hosting domain.
Attackers are hiding command-and-control traffic inside Google services, rendering traditional network security controls largely ineffective.
