StartFlagExploit is an open-source (GPL-2.0-only) Android app by ChickenHook. The APK we host is 2.0 MB, it needs Android 10 or newer, and it declares no permissions at all.
The file on this page is StartFlagExploit 1.0, 2.03 MB, and it installs on Android 10 and newer.
We compared the signing certificate of this build with the certificate recorded the first time org.chickenhook.startflagexploit entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.
The manifest inside the APK declares no permissions at all.
Its licence is GPL-2.0-only. We took this build from F-Droid, and the source for this exact version is linked below.
The most recent release upstream is from Jun 9, 2020, over 6 years ago. It still installs; it is simply not being updated.
We do not show a star rating or an install count for this page: we have no measured figure for either, and a number we cannot source is worth less than an empty field.
