Ouvis veezon VZ1 Hacking ( and clones alike )

When I first bought this camera, I read the reviews from all the people that complained their camara got hack because they left the default (no pass) password, and someone took control over their cam. Been a bit savvy and having a “decent” firewall (Fortigate) at home, the first thing I did when connecting the camera to my home is to look at all the active connections the device was trying to make.


The camera software claimed it didn’t need the IP of the device, just a qr code that would pair the camera with the app on my phone. From the screenshot below it looks like it’s a UDP tunnel, but keep in mind I don’t have upnp enabled, so it’s probably using some magic to connect the 2 devices through UDP.


The other connections are: = Google DNS = AWS server on port 32100 =AWS server on port 32100 = Chinnese IP on port 32100 ( I blocked it for now and all functions still work. )


Looking a bit more into the chinese ip it looks like from Aliyun Computing. A quick google search tells me it seems aliyun is the chinese counter part of Amazon AWS services, it seem like Aliuyun is now Alibaba Cloud services.


Looking at the communication generate from the app on my phone. It seems the trick the camera uses to have both devices to connect to a third party device, that will help out do a UDP Pinhole between both devices to connect directly via UDP without doing port forwarding.

For now I blocked access to the for the China IP and keep an eye on what traffic goes on the system. Based on the research the encoder process is the one that connect between devices, but i’m worried about the sh process listening on those udp ports.

Dear Harry,
I apologize for any delay and inconvenience you may have experienced. I can assure you, I will do what I can to assist.

The 42 and 32LD450 are identical except for screen size. You can consider the 32LD450 and the 42LD450 license and source code identical.

Other than adjusting your antenna, maybe raising it higher, there isn’t much else we can do. If the issue persists, then it may require service.
