Why is my Nvidia tablet looking for chinese servers(baidu.com)? I am not sure if this is the right area for the question, or if it is even a big deal, but here i go.
When using by Nvidia tablet to develop an app I realized that it was attempting to reach a server in china. this doesn't make sense to me because I don't have any apps that I would think would try to do this. What I would like to know is if this is a security concern?

Most relevant part of the article:


  Leaks sensitive data on startup
  
  Upon application launch, we observed Baidu Browser sending an HTTP POST request to
  https://hmma.baidu.com/app.gif
  
  The body of this HTTP request is a gzipped JSON file. The JSON file contains a list of fields with various details about the phone and the user, some in plain text and others encrypted.
  
  Unencrypted fields in the JSON file include:
  
  
  o: the user’s operating system (e.g., “Android”)
  n: Baidu Browser version number
  w, h: width and height, respectively, of the screen in pixels
  gl: GPS coordinates and time of last GPS update
  
  
  Some fields are encrypted using AES+ECB with the hard-coded ASCII-encoded key
  h9YLQoINGWyOBYYk
  
  and then Base64 encoded. These fields include:
  
  
  dd: IMEI number
  ii: a string containing the phone’s IMEI number written backwards and an MD5 hash of Android software version information
  wl2: list of all in-range wireless networks and their MAC addresses and signal strengths
  
  
  With knowledge of the hard-coded key, these fields can easily be decrypted. The source code for a python script for decrypting these fields is available here.


And then there's Baidu's response (PDF file hosted at citizenlab.org). They don't seem to see an issue in collecting this data, they just acknowledge that they need to improve their encryption:


  Baidu endeavors to collect data in a way consistent with the highest standards of security and 
  user privacy in the industry. We disclose our practices in our terms of service under privacy 
  rights as detailed here (Chinese): https://www.baidu.com/duty/yinsiquan.html 
  
  We're grateful of Citizen Lab for being mindful of data security in transmission and we have 
  already made substantial progress toward ensuring that any such transmission will be secure.


So citizenlab's article is probably no more describing what you can see on the net nowadays.
