"description": "From the defender\u2019s view: an app retrieves opaque code (DEX/SO/JAR/JS) over the network or IPC, writes it into an app-writable path, optionally performs verification-bypass behaviors (reflection, addJavascriptInterface exposure, or execmem friction), and then loads/executes that code via DexClassLoader/PathClassLoader, dlopen, or WebView bridge invocation within a short window. The analytic correlates Network Content \u2192 File Creation/Modification \u2192 OS API Execution (loader/syscall/SELinux friction) \u2192 Module Load (DexClassLoader/dlopen) and, for WebView paths, Application Log signals of JavaScript interface attachment.",
