TUTK is technicallyTaiwanese, which I guess is somewhat debatable worldwide as to whether one counts it as a part of China or not (CCP/PRC China says it is China and has strong-armed the international community into using this distinction), and ROC China (and most in Taiwan) says it’s actually distinct from CCP/PRC China), but are powerless to do much about it. So maybe TUTK is Chinese and maybe it’s not depending on your point of view (agree with China, then yes, agree with Taiwan, then no).
But here’s the reason I’m bringing this up (since there are few threads discussing TUTK): There’s an interesting article about a recently discovered TUTK vulnerability:
“Successful exploitation of this vulnerability could permit unauthorized access to sensitive information, such as camera audio/video feeds,” CISA said in the alert.
ThroughTek recommends original equipment manufacturers (OEMs) using SDK 3.1.10 and above to enable AuthKey and DTLS, and those relying on an SDK version prior to 3.1.10 to upgrade the library to version 22.214.171.124 or v126.96.36.199 and enable AuthKey/DTLS.
I don’t know what version of the SDK Wyze uses, but I assume they either have, or will be upgrading their SDK to 3.1.10 (or higher). Regardless, I believe Wyze has taken greater precautions than most companies with their TUTK connections. As I understand it, ThroughTek is only used by Wyze to locate the cameras and telli f they are online, rather than the actual camera feeds themselves (which for Wyze is a direct connection).
Still, it does make one wonder if some of the weird (rare) posts about “hearing someone through the camera” or some-such are related to this issue. Seems like an easy fix though, just upgrade the SDK (if it’s not already) and ensure AuthKey and DTLS are enabled. They might already be, and even if they aren’t, I’m not sure this issue would apply to Wyze anyway since they implemented steps to prevent TUTK from accessing the Wyze camera stream directly anyway as explained so well in that link you (Customer) posted. Still, I thought it was an interesting read anyway.
