Spawing An Export

This one was also a wasted challenge that I was overthinking but it was reallyyyyyyyyy easy

Opening up the source code with jadx-gui . We check the MainActivity but nothing interestong was going on but there was a flag function in another section being defined.

Looking at the Manifest file we can observe the flag Activity here. The Activity just wasn't exported or "called"

We can use ActivityManager or am here with the -n flag to specify the component name of the activity we want to start

adb shell am start -n definitely.notvulnerable.spawn/.flag

Activity started. Now, we check the emulator

Flag: bbctf{in$ECuRe_EXPORtED_aCt!vl71es}
