I have a cheap Chinese CCTV camera system at home, I wanted to explore the system up close.
I did a nmap scan of the system and found that port 23 (telnet) was open.

Nmap scan report for (192.168.1.88) Host is up (0.0051s latency). Not shown: 995 closed ports PORT STATE SERVICE 23/tcp open telnet 80/tcp open http 5000/tcp open upnp 8000/tcp open http-alt 10002/tcp open documentum MAC Address: 00:5A:E8:AB:EB:9C (Unknown) |
I kicked off a connection and saw that it was contactable. I tried a whole bunch of default username and passwords for these CCTV boxes but none worked.
So I tried googling it strange login prompt.

telnet 192.168.1.88 Trying 192.168.1.88... Connected to 192.168.1.88. Escape character is '^]'. GM login: Password |
I googled “GM Login”. Turns out GM stands for Grain Media and its default password is

GM login: root Password: GM8182 |
Ill continue to experiment with the machine and post my findings.
