- -**Read more on the blog:** - -This framework helps with Flutter apps reverse engineering using the patched version of the Flutter library which is already compiled and ready for app repacking. This library has snapshot deserialization process modified to allow you perform dynamic analysis in a convenient way. - -Key features: - -- `socket.cc` is patched for traffic monitoring and interception; -- `dart.cc` is modified to print classes, functions and some fields; -- display absolute code offset for functions; -- contains minor changes for successful compilation; -- if you would like to implement your own patches, manual Flutter code changes are supported using a specially crafted `Dockerfile`. - -### Supported engines - -- Android: arm64, arm32; -- iOS: arm64; -- Release: Stable, Beta - -### Install - -``` -# Linux, Windows, MacOS -pip3 install reflutter==0.8.5 -``` - -### Usage - -```console -impact@f:~$ reflutter main.apk - -Please enter your Burp Suite IP: - -SnapshotHash: 8ee4ef7a67df9845fba331734198a953 -The resulting apk file: ./release.RE.apk -Please sign the apk file - -impact@f:~$ reflutter main.ipa -``` - -### Traffic interception - -You need to specify the IP of your Burp Suite Proxy Server located in the same network where the device with the Flutter application is. Then configure the Proxy in `BurpSuite -> Listener Proxy -> Options tab`: - -- Add port: `8083` -- Bind to address: `All interfaces` -- Request handling: Support invisible proxying = `True` - -

- -No certificate installation or root access is required for Android. reFlutter also allows bypassing some of the Flutter certificate pinning implementations. - -> ⚠️ **Note:** Starting from Flutter version **3.24.0** (snapshot hash: `80a49c7111088100a233b2ae788e1f48`), the hardcoded proxy IP and port have been removed. You now need to configure your proxy directly on the device. - -#### On Android: - -Use ADB to configure the device’s proxy: - -```bash -adb -s shell "settings put global http_proxy " -``` - -Sign, align, and install the APK. Optionally configure **TunProxy** to route traffic through Burp Suite. - -#### On iOS: - -Sign and install the IPA. Configure **Potatso** to use your Burp Suite proxy server. - -### Usage on Android - -The resulting apk must be aligned and signed. A recommended tool is [uber-apk-signer](https://github.com/patrickfav/uber-apk-signer/releases/tag/v1.2.1): - -```bash -java -jar uber-apk-signer.jar --allowResign -a release.RE.apk -``` - -Run the app on a device. Determine `_kDartIsolateSnapshotInstructions` via binary search. reFlutter writes the dump file to the app's root folder and sets 777 permissions. Retrieve it using: - -```bash -adb -d shell "cat /data/data//dump.dart" > dump.dart -``` - -
-file contents - -```dart -Library:'package:anyapp/navigation/DeepLinkImpl.dart' Class: Navigation extends Object { -String* DeepUrl = anyapp://evil.com/ ; -... -``` - -
- -### Usage on iOS - -After running `reflutter main.ipa`, execute the app on device. The dump file path is printed to Xcode console logs: - -``` -Current working dir: /private/var/mobile/Containers/Data/Application//dump.dart -``` - -Retrieve the file from the device. - -

- -### Frida - -Use dump offsets in the Frida [script](https://github.com/Impact-I/reFlutter/blob/main/frida.js): - -```bash -frida -U -f -l frida.js -``` - -To find `_kDartIsolateSnapshotInstructions`: - -```bash -readelf -Ws libapp.so -``` - -Look for the `Value` field. - -### To Do - -- [x] Display absolute code offset for functions; -- [ ] Extract more strings and fields; -- [x] Add socket patch; -- [ ] Extend engine support to Debug using Fork and Github Actions; -- [ ] Improve detection of `App.framework` and `libapp.so` inside zip archive - -### Build Engine - -Engines are built using [GitHub Actions](https://github.com/Impact-I/reFlutter/actions) based on data in [enginehash.csv](https://github.com/Impact-I/reFlutter/blob/main/enginehash.csv). Snapshot hash is retrieved from: - -``` -https://storage.googleapis.com/flutter_infra_release/flutter//android-arm64-release/linux-x64.zip -``` - -

- -### Custom Build - -Manual Flutter code patching is supported using Docker: - -```bash -git clone https://github.com/Impact-I/reFlutter && cd reFlutter -docker build -t reflutter -f Dockerfile . -``` - -Run with: - -```bash -docker run -it -v "$(pwd):/t" -e HASH_PATCH= -e COMMIT= reflutter -``` - -Example: - -```bash -docker run -it -v "$(pwd):/t" -e HASH_PATCH=aa64af18e7d086041ac127cc4bc50c5e -e COMMIT=d44b5a94c976fbb65815374f61ab5392a220b084 reflutter -``` - -#### Example: Build Android ARM64 (Linux/Windows) - -```bash -docker run -e WAIT=300 -e x64=0 -e arm=0 -e HASH_PATCH= -e COMMIT= --rm -iv${PWD}:/t reflutter -``` - -Flags: - -- `-e x64=0`: disables x64 build -- `-e arm64=0`: disables arm64 build -- `-e arm=0`: disables arm32 build -- `-e WAIT=300`: time in seconds to modify source before build -- `-e HASH_PATCH`: snapshot hash from `enginehash.csv` -- `-e COMMIT`: engine commit hash -
