Hack for Cheap Chinese Goke GK7102 Cloud IP Cameras

This hack is for various Chinese Goke GK7102 based IP Cameras. There are few different firmware varieties across various brands of cameras, which means it is impossible to know what exactly will work for you. Older firmware are more hackable because the root filesystem is mounted read/write. In the new firmwares the root filesystem is mounted read-only but the /home directory is writeable. This hack is based on (https://github.com/ant-thomas/zsgx1hacks)

Working on the following camera models

V-Tac 1080P IP Indoor Camera (read-only version)
ZS-GX1
Snowman SRC-001
GUUDGO GD-SC01
GUUDGO GD-SC03
GUUDGO GD-SC11
Digoo DG-W01F
Digoo DG-MYQ
YSA CIPC-GC13H
KERUI CIPC-GC15HE (read-only version)
EYEPLUS CIPC-GC13H (read-only version)
HIP291-1M
2M-AI
others on the GOKE processor: GK7102 (GK7102S)

Features

Blocking cloud hosts
New version of BusyBox v1.26.2
Configurable settings
BusyBox FTP Server
dropbear SSH Server: root can login ssh without password
WebUI PTZ - (http://192.168.200.1:8080/cgi-bin/webui)
Debug and diagnostics tools: andrew-d/static-binaries
Change login credentials to user: root password: cxlinux
Improved terminal experience
Wi-Fi configuration without cloud account

Installation

Current version works only from microSD card and do not require installation. It should work normaly on both old and new read-only firmwares.

Download the hack
Copy contents of folder sdcard to the main directory of a vfat/fat32 formatted microSD card
Change options in config.txt
Insert microSD card into camera and reboot the device
Enjoy

Security

The security of these devices is terrible.

DO NOT expose these cameras to the internet.
For this hack, config.txt is used to decide what servers you want to run.
This hack is blocking the communication with the cloud providers, see /media/hack/etc/hosts.
By default the camera wants to use some app YCC365 Plus
tcpdump binary is included with this hack on /media/hack/bin/tcpdump
Logs in /tmp/closelicamera.log
The device was communicating with servers of icloseli.cn, icloseli.com and arcsoft.com
Some cameras are trying to use 30.108.91.227 and 47.104.139.168, even with the blocked hosts.

DO NOT expose these cameras to the internet.

Instructions

How to check version

Using an onvif tool/app like Onvifer (Android) should give firmware version.
You should also be able to find the firmware version by logging in via telnet and excuting the command
If you have already configured the camera with the cloud app there should be some info within the app showing firmware version.

ls /tmp | grep -F 3. or ls /tmp | head -1

Default Credentials

IP Port Service Username Password

192.168.200.1 23 telnet root cxlinux

RTSP Connection

rtsp://admin:@192.168.200.1:554
rtsp://admin:@192.168.200.1:8001

Debug Scripts and Files

By default, the startup script /home/start.sh will try to load and run some commands

Files running from SD Card

To run debug scripts create a file debug_cmd.sh on an SD card and you will be able to execute bash commands from it.

Files copied from SD Card to /home

*-hwcfg.ini, *-VOICE.tgz, *-ptz.cfg, *-hardinfo.bin, *-custom_init.sh

File will be flashed

firmware.bin

Connect to Wi-fi network

On the SD card, create the cls.conf file and write these 3 lines in it. Change your_wifi_ssid and your_wifi_password with your credentials.

[cls_server]
ssid = your_wifi_ssid
passwd = your_wifi_password
