Am I hacked?

[FlipNJ]

All of my cameras have unknown users that can't be deleted because they are reserved users. Each memo is CISA.
I'm not super concerned but need to purge those users. Anyone have info?

1- disconnect from the Internet

2- in the NVR GUI (or individual cameras) do a factory default

What is hacked? The NVR or individual cams?
What model?
What firmware version?

Ok, you need a BI guy, I'm an NVR guy

Still I'd disconnect.

Are you using P2P or is P2P enabled on your cams?
If so, any firmware prior to Aug 2024 can be comprimised

Is port forwarding used?
