An App intended for fuzzing the Binder interface and System Services of Android.
About this app
BinderFuzzy is a fuzzer that can generate binder events in order to pentest system services running on the Android operating system (https://developer.android.com/reference/android/os/Binder, https://source.android.com/devices/architecture/hidl/binder-ipc). You can validate if system services have correct error handling or transfer binder objects / tokens of other services in order to validate if the target system service validates binder arguments.
This Project covers following features:
* Browse managers and binder interfaces. * Execute Fuzzy tasks * Configure argument lists for each parameter of the method to fuzz * Read logs of recent tasks * Use python3 cli (optional) to execute fuzzer from desktop. * Define fuzzer script and execute via cli
Enjoy our App!

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.chickenhook.binderfuzzy is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for BinderFuzzy - Pentest Android Services, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of BinderFuzzy - Pentest Android Services, and a listing is removed when the evidence for it stops holding up.
