Despite being a relatively recent build, the Flock camera was running Android 8.1. This version of Android was released in 2017, and officially stopped getting support from Google in 2021 (see the Android end-of-life page for more info). And despite Google publishing security fixes for Android 8.1 until 2021, the Android patch level is 2018-06-05. This camera is missing Android security updates for the last eight years.
kali Linux with metasploit will do a lot of the heavy lifting. I imagine you could turn your local installations into a free wifi access point, for starters.

download kali onto a computer and it should have an application called metasploit.
open your terminal and type in “man metasploit” and it should have enough info on the actual application to get you started but if you need more info go on youtube or kali docs
