The GitHub Security Lab deployed an open‑source AI‑driven security agent that integrates static analysis, dynamic taint tracking, and LLM‑guided prompt engineering to autonomously scan Android application codebases. Configured with taskflows for intent redirection, insecure data storage, native library fuzzing, and WebView XSS, the agent analyzed ten popular open‑source Android apps over six weeks, surfacing 24 previously unknown vulnerabilities—including five critical RCEs in native components—and facilitated responsible disclosure, CVE assignment, and patching. The agent’s code, Docker image, taskflow templates, and runner script were released publicly to enable reproducible scans.
