I need help ensuring my Ring camera security. Your tasks will include: - Find each camera's IP address. - Test whether the cameras can be opened on the network. - Set up access to view the camera feed - See if cameras had access from other IP sources in past 2 months - see who else has been in my FB messenger in last 2 months - See who else logged into Snapchat in last 2 months Also, I need you to check for unauthorized access. I want you to investigate: - Camera app login and device history - Router or Wi-Fi network connection history Ideal skills include: - Networking knowledge - Familiarity with Ring cameras - Experience with security audits My ex fiancé has had access to my office computer this summer. I’ve changed Passwords a couple times. She’s continued to request access so she could “help me out.” I allowed her, not thinking she was getting my passwords for a bunch of accounts and getting access to my Apple account with all my passwords. Also looks like she had sent two people to live in my basement that she claimed were homeless and I said I’d help him out for a couple months. They seem to be very distant from me and always seem to know when I wasn’t in the house to go upstairs into the kitchen. I think my ex gave them access to my cameras. Also noticed two different Wi-Fi routers nearby that aren’t around anymore after I kicked them out wondering if they might have bugged the house with audio and visual surveillance. Not sure if they came back to get the items but I feel the house was bugged. Also footage is missing from specific times when my computer Internet stopped working and my kitchen camera that would show anyone going to my hallway with my room. It was shut off for two days.
