Chrome (and other) extensions can appear benign at review time but load remote iframes or runtime payloads that exfiltrate data (reports mention ~260k installs of malicious AI assistant extensions, including Gmail scraping). Security teams and store reviewers lack a fast, automated way to run extensions in instrumented browsers and observe runtime behavior (DOM reads, network endpoints, iframe injections, runtime evals) to catch server-driven malicious behavior.
Why now: Remote runtime payloads and server-driven behavior are increasingly used in supply-chain attacks; headless/browser instrumentation is now cheap and automatable and demand is rising due to frequent AI-branded malicious extensions.
A SaaS that automatically downloads CRX/XPI packages or installs extensions into instrumented headless browsers and runs automated interaction scripts to detect suspicious runtime behaviors: remote iframe loads, network calls to unknown endpoints, attempts to read page content (Gmail/Slack), dynamic code injection/eval, and data exfiltration patterns. The MVP includes a crawler to fetch store listings, sandboxed execution traces, a risk score, downloadable reports, and webhooks/API for integration with app stores or enterprise SIEMs.
Built for: Browser extension store security teams, enterprise security teams (SOC/Threat Ops), and security researchers who vet or ingest extensions at scale.
