Looking for a nudge in the right direction
Hi,
My haxorware modem went offline a couple years ago with the new cc security, and i gave up and put it away. I have been interested in getting it going lately and am looking for some advice. I am very interested in learning how it works and don't mind reading and studying DOCSIS but I'm not sure where to go. I have also switched ISPs and don't use cc anymore. Here is my telnet log:
Code:

Since my mac is not provisioned I get the unknown.bin config file which fails the CVC check.

First, my subbed modem is an Arris mg5225g which is a modem and router in one. I don't think I can scan for macs, because you're supposed to be connected directly to modem, not behind a router. I tried putting my pc in dmz and scanning but it doesn't seem to work. Is there a way to scan with my equipment, or is that the wrong approach altogether? I was thinking if I could see macs and config files on my network I could play around with those to at least get more information on the security my cmts is running.

I don't know a whole lot about snmp but it seems like that might hold a key for me? Problem is I can't get any information with the unknown.bin config file sent to my modem. I think I would at least need a community string, but where can i get that if its not in the config file?

I keep reading that I need to understand the handshake and learn how to make my cm send what the cmts is wanting to see, but I can't get past this unknown.bin problem.

I really do want to learn more about this and I like to read and understand these things (I basically taught myself c++ just from reading online), I'm just hoping someone can point me in the right direction.

RE: Looking for a nudge in the right direction
The snmp public string is actually in the log you posted, but it seems you have bigger issues, log indicates that your modem strings mismatch what the cmts expects, see your spoof settings.

also get yourself Vultureware and open the config you are being served, you can learn a lot from it.

RE: Looking for a nudge in the right direction
I have vultureware and have read this config already, I guess I don't know what I am looking for because I don't see anything useful. How do I know what to spoof if it's not in the config? (see attached screenshot of config file) Also I thought the stealth page in haxor is useless now, how would I change the strings correctly?

Is the community string simply "public"? because I can't see anything else? I thought it was a random string of characters like "gHzrGTb" or something?

spoofs all wrong you can see the cvc in the config
