Redefined SSL Common Names verifier

This app uses self defined certificate verifier. If it is not properly configured it could allow attackers to do MITM attacks with their valid certificate without your knowledge.

WebView code execution

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

AWS Credentials

Everyone can use it to access your resources.

Dangerous filesystem permissions

Files created with these methods could be worldwide readable.

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.

Exported components

Other applications could access the interfaces.

SQLite database found
