Error Messages

We are given another apk file. I used jadx-gui to analyze the source code. Looking straight in MainActivity, we see a getFlag() function

After being defined, the function gets called and the string value gets logged. To get the flag we can use Logcat from the adb utility

I ran the apk on my emulator

And on my terminal, I ran Logcat and grepped the flag

❯ adb logcat | grep "bbctf"

Flag: bbctf{V3rBo53_lO9G1n6_8a0bdbd84}
