Reverse engineering of a Huawei P20 from China - Episode 2

Thread ⬇️
I intercepted the communications made by the Huawei P20 and this is not good...
The phone sends a request to all these websites. The 1st observation, we can do is that almost all communications are unencrypted.
This request to the subdomain track.uc.com to the endpoint collect seems interesting
In this request, the phone is sending
- your country
- your province
- your city
- phone locale
- the website you requested (here google.com)
They didn't enforce the strict transport security aka track.uc.com is working... 🤦‍♂️
This domain is the property of UCWeb Inc. the company behind the UC Browser
Well, this request is not shady at all :sarcasm:
It sending a lot of thing I cannot read for now, I need to find the corresponding code.
If you open myhwclouds.com with chrome, you will have a warning
This endpoint is part of the Huawei Cloud from the "Object Storage Service" family
Not shady at all...
Reminder: I didn't use the phone, these requests are done without any user interactions
According to virustotal, 8.37.232.1 is a subdomain of ucweb.com which the property of MILEWEB, INC
Wow this is the number of requests done when I did airplane mode on/off!
There is a lot of thing to find in this phone but now I need to sleep 😄. End of the episode 2, see you for the episode 3!
