Project CAV3RN uses Google Apps Script for stealthy C2 in Israel

A modular espionage framework targeting entities in Israel has evolved to incorporate sophisticated command-and-control capabilities. The framework employs DNS A-record responses to dynamically select between direct HTTPS connections and a Google Apps Script relay for each transaction, enabling operators to rotate communication channels and deployment identifiers. The communication module uses DNS infrastructure to validate and update Google Apps Script deployment IDs, while XOR encoding obfuscates command-and-control traffic. An inter-component broker coordinates framework DLL components, enabling runtime upgrades without system restarts. The infrastructure leveraged a previously expired Israeli domain, now repurposed with custom authoritative DNS servers, alongside legitimate Google services to blend malicious traffic with normal network activity.
