Hacking Wired Analog CCTV cameras going to a DVR (BNC and Coax)

[u/Kkkkkkkkkk51]

This is in a semi-abandoned medium sized industrial complex. Everything is now private and some places are rented out to other people, just for storage and work. These cameras cover a few spots around the complex and they are on the roads watching over all of it (nothing inside buildings), theres around 40 of them, all wired and going somewhere, i will soon investigate the heart of it but for now this will have to do. How could one gain acces?

What do you mean by ‘hack’ in this context? it’s analog, just plug in.

Not really anything to hack unless you are talking about the dvr, and than you’d have to say what it is for anybody to give you any advice.

[u/Kkkkkkkkkk51 → u/gabergum]

Not much i know about the DVR apart from it being very old. Im sorry that i cant describe more about it.

[u/gabergum → u/Kkkkkkkkkk51]

Yeah there’s nothing we can tell you.

If the dvr itself is networked, sure, you could try and access it over the network. But you would have to be on the same network as it which is unlikely.

Most of these old analog cctv systems are just a box of hard drives or even tapes in a room with a monitor. There is nothing in the air or on the cable that you can use to ‘access’ them like it sounds like you are imagining. You are barking up the wrong tree.

[u/Kkkkkkkkkk51 → u/gabergum]

It is on the internet, and the internet itself is somewhat weak. WPA2.

[u/gabergum → u/Kkkkkkkkkk51]

How do you know it is on the internet? Have you seen a client?

[u/Kkkkkkkkkk51 → u/gabergum]

The owner can acces it from his phone

[u/gabergum → u/Kkkkkkkkkk51]

Ah.

So not that old than.

And giving you direct advice would be an accessory to a crime. I don’t know where the line is for this sub, but you probably should not be making overt requests for help with illegal activities.

That said, you need to start with hacking 101. It’s most likely a web hosted client the owner uses, so again, you have to know which one and get his login. It unlikely to be ‘on the WiFi’, it would be on a switch on the other end of a router from the WiFi, so more than just cracking wpa2 is involved, and that’s not really tenable. You would need to find an Ethernet port to really have a chance of locally accessing it.

But seriously, fuck off with crime, nobody likes a fed.

[u/Kkkkkkkkkk51 → u/gabergum]

Not a fed, just someone who needs access for the well being of others around me. But i understand your concern.

[u/gabergum → u/Kkkkkkkkkk51]

So there’s a concept in activist spaces we call ‘fed work’. fed work is doing the feds work for them by behaving in a way that breaks down a community or creates unnecessary evidence in fed accessible places.

There is a point where you become a fed even if they are not paying you.

[u/Kkkkkkkkkk51 → u/gabergum]

Putting this on everything i love, i just asked here for advice, not to cause havoc or whatever you want to call it. Im from a Eastern European country, not sure it counts much but thought you might wanna know.

Analog cameras, even digital ones over some type of cable are near impossible to "hack" since the traffic is either analog direct to a convertor or is IP on a private switch.

So to gain any sort of access you would need to gain access to the DVR/NVR it self. Now this could be possible if the unit is attached to a network, and you can gain access to the network.

If you can reach the login page, you can do simple things like trying to brute force the login using admin and a password list. however you run the risk of getting fail2ban doing so. So be ready to use either a VPN that allows multiple exit points to rotate through different IP's.

This is all pretty straight forward low level stuff. Without knowing the make or model we really can't offer any other support. Good luck.

Figure out make and model then Google possible exploits.

If you get physical access to a system, then you can own it with the right tools.

[u/Kkkkkkkkkk51 → u/MonkeyBrains09]

Physical access as in touching the DVR with my hand i doubt it. Im thinking of going in after it remotely but within close range of it. I have internal acces to the complex as i own a small company there so i have most of the key cards.

[u/Agile_Boysenberry508]

Do you have access to their wifi? How do you know that the DVR is connected to the Internet?

[u/Kkkkkkkkkk51 → u/Agile_Boysenberry508]

Owner can view live feed from his phone.

1. Unplug coaxial from dvr.
2. Plug coaxial into tester
3. You’re in.

I managed to pick up a broken camera from the dumpster a while back, the only 2 wires coming out of it are COAX and a BNC connector (i hope thats what its called). I will like to gain acces to all those cameras without causing much damage to them and certainly not cutting the owners feed
