Unsafe deleting

All items deleted with 'file.delete()' could be recovered.

Suspicious files

Are you sure these files should be here?

Dynamic Code Loading

Code for 'DexClassLoader' could be tampered.

WebView JavaScript enabled

WebView 'setJavaScriptEnabled(true)' could be exploited during cross-site scripting attacks.

SD-card access

SD-cards and other external storages have 'worldwide read' policy.

WebView files access

Control of WebView context allows to access local files.

• CRITICAL
Customized SSL

Check certificate validation. Do not create or redefine X509Certificate class methods by yourself, if you don't understand risks. Use the existing API.

Dangerous filesystem permissions

Files created with these methods could be worldwide readable.

WebView code execution

WebView 'addJavascriptInterface' could be used to control the host app with JavaScript bindings. Remote Code Execution (RCE) is possible.

WebView SSL handling enabled

WebView with 'handler.proceed();' allows connection to continue even if the SSL certificate validation is failed.
