So a while back, I purchased one of these things: Defender Sentinel 21031. It is a pretty good unit. Cameras are nice. It’s basically for home monitoring.

After writing to the company, it turns out they don’t reveal the root password to the device. That was an unacceptable answer for me, so I took to checking out what’s under the hood.
Once that was done, I was able to boot into single user mode, and extract the /etc/passwd file which contained:
I’m currently running John the Ripper on the hash to see what the password is. I’ll update this post when I get it.
