Validating Chrome Extensions: Organizational Security

🔒 This article by Stan Kaminsky reviews Athanasios Giatsos’ Security Analyst Summit 2025 talk and explains why malicious browser extensions are a major blind spot for organizations. It outlines how extensions can access cookies, local storage, proxy settings, clipboard and screen capture, enabling session and account theft, espionage, ad fraud and crypto theft, and why Manifest V3 reduces but does not eliminate risk. Practical controls described include formal extension policies and allowlists, disabling developer mode, version pinning and testing of updates, EDR and SIEM-based monitoring, and the use of specialized vetting tools for deeper analysis.
