なぜ私のNVIDIAタブレットが中国のサーバー（Baidu.com）を探しているのですか？ -- security フィールド と logging フィールド と bloatware フィールド android 関連 問題

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 userxe2x80x99s operating system (e.g., xe2x80x9cAndroidxe2x80x9d)
• 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 phonexe2x80x99s 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 morexc2xa0describing what you can see on the net nowadays.
