C210 Tapo camera
IP Cameras are a nightmare for our privacy. For this reason I am reverse engineering a Tp-Link Tapo C210's firmware and its relative app in order to prevent them from sending any data to untrusted servers. There are better resources than mine: see https://github.com/nervous-inhuman/tplink-tapo-c200-re and https://drmnsamoliu.github.io/. Be careful use those resources mindfully, as they are about Tapo C200, whereas this repository focuses on the C210. Despite being esthetically equivalent and having a similar name, their hardware is completely different. The C200 is based on a MIPS microprocessor, whereas the C210 is based on the ARM-based MStar SSC335 chipset.
In particular, I will focus on
- the reverse engineering of the app in order to be able to use the camera without a Tp-Link account;
- the reverse engineering of the firmware to strip off the portions of code sending the video stream to their servers, or better self-compile a clean firmware. Good news you can install OpenIPC, having a look at this link
How these cameras were designed to work
- You download a proprietary app (Tp-Link Tapo) and create an account without which the camera can not work;
- You use said app to instruct the camera to use a specified Wi-Fi AP;
- The camera sends the video stream not end-to-end encrypted to servers we have no control over;
- You have the possibility to update the camera's firmware through its app. This expands the attack surface for a hacker or from the company itself to push a malicious update.
What we can do
As of today, we have:
- Libre NVR solutions (iSpy, ZoneMinder, ...);
- A collection of open source software to control these cameras through undocumented APIs, see my collection.
Nonethless, you still need the proprietary app and a Tp-Link account the first time you boot the camera up and NVRs will not stop the camera from sending the video stream to their servers without using a firewall.
This repository aims to resolve these issues.
