Note: only MacOS for Desktops and Android OS for mobile phones are currently supported

Note: Please do not use the emulator, use the phisical device instead.

Before Downloading the Project

Installing Flutter SDK

Here is an official insrtuction how to download the Flutter SDK https://flutter.dev/docs/get-started/install After installing the Flutter run the following two commands in the terminal

flutter channel dev
flutter upgrade --force

After that we have to enable MacOS configuration

flutter config --enable-macos-desktop

Installing NodeJS

Here is an official insrtuction how to download the NodeJS https://nodejs.org/en/download/ LTS version is recommended

Installing Adnroid SDK Tools

Here is an offical insrtuction how to download the Adnroid Studio and Android SDK https://developer.android.com/studio

After installing be sure that Flutter and NodeJS in the Path. Android SDK tools probably will not be in the Path by default, and because of that fact it will be some times required to locate to the SDK folder or SDK can be moved to the math manually.

Installing Xcode

For MacOS build Xcode 12 is required. It can be easily downloaded from the AppStore for Mac

Installing the Project

Clone the project to the any directory bt the following command:

git clone https://github.com/DarkKnight1005/security_scaner.git

Open the project folder in the code redactor (Visual Studio Code is recommended)

After that move to the ./AnyProxy/bin whih locates inside the project or in VS code type into the terminal following command

npm install --force

After that just in order to be on the safe side run the following command:

npm audit fix --force

Trusting the Certificate

This project using AnyProxy for the proxy side. Now the Certificate must be trusted to decrypt HTTPS traffic as mentioned in the report-research. In the folder ./AnyProxy/bin run the following command:

./anyproxy-ca 

After that do the required things to generate the Certificate. Then locate to the relevant folder with the generated certificate and double click to the rootCA.crt. After that KeyChain will open. Double-click to the AnyProxy certificate in the KeyCahin and properties window will pop up. Find Trust, click and expand it and change When using this certificate from Use System Defaults to Always Trust. Run ./anyproxy-ca to be sure that certificate is trusted.

Building app

For MacOS

NOTE: Be sure that MacOS version is at least 11.0 (Big Sur) or higher, in other cases, unknown errors may occur.

Locate to the project directory and run the following command:

flutter pub get

After that just select macOS(darwin-x64) or just macOS from the down right corner of the VS code and run the App.

Configuration for the MacOS is ready, now you can Analyze all traffic of the PC. By clicking Connect App will start the server and connect PC to the proxy server. By clicking Disconnect App will stop the server and disconnect PC from it.

For Android OS

NOTE: Be sure that Android version is at least 5.1 (SDK 21) or higher, in other cases, unknown errors may occur.

Trusting the Certificate

The first thing which is required to do is that install certificate tot the phone. It is the same certificate which was generated before for the PC. To trust to certificate just send it to the mobile device then tap on it.

1. Select VPN and Apps and name as you wish, then submit.
2. Select WIFI and name as you wish, then submit.

Downloading Proxy connector

After that it is highly recommended to donwload an app from the following link because of the fact that connecttion to proxy firectly from the Flutter a bit problematic and the native way is the much better. https://github.com/theappbusiness/android-proxy-toggle

Manual Connection

To connect manually it is requested to go the WIFI settings of the phone, then forget disconnect from the WIFI. Then connect again, and in advanced settings during the connection select manual in Proxy settings and write IP and Port for the Porxy.

After the installation of Proxy Toggle it is required to run MacOS application, click to the ServerMobile, then in the Proxy Toggle app write down Server's or Local Machines IP address. which can be found at the center top of the applicaiton with the label Server IP. Or the following command can be executed in order to find it:

sudo ifconfig

Seting Up

Now in Proxy Toggle it is needed to write the IP of the Local machine to the related field and Port will be 8090. Then press connect.

After successful connection to the proxy, switch to our app and and in the Text Field write that IP address again and press submit. After all this steps everything is ready. You can now surf in the internet and after just visiting onw site you can switch back to the app and press All. And all the traffic will be shown.

NOTE: By default realtime update and push notifications are disabled. In order to see the traffic, just every time tap the All button, then program will refresh captured internet traffic.
