OnePlus sends IMEI and the phone manufacturer to a Chinese server

by do son · January 27, 2018

Security researcher Elliot Alderson found a file called badword.txt in OnePlus clipboard application, which contains a large number of Chinese phrases such as “Chairman, Vice President, Deputy Director, Associate Professor, Deputy Heads, General, Private Message, shipping, Address, email, …”. This badword.txt is duplicated in a zip file called pattern. This archive contains 7 files: – badword.txt – brackets.txt – end.txt – follow.txt – key.txt – start.txt . All these files are used in an obfuscated package which seems to be an Android library from teddymobile. TeddyMobile is a Chinese company, they worked with a lot of manufacturers including Oppo.

Researchers suspect that one plus one sends the user’s various data to the servers of Chinese companies without the user’s consent.

TeddyMobile package might be able to grab all sorts of data from a phone.

In the TeddyMobile's package com.ted, they have a class called SysInfoUtil. This class contains the following methods:
– getAndroidID
– getCPUSerial
– getDeviceId
– getHardwareSerialNumber
– getIMEI
– getIPAddress
– getMacAddress
– getPhoneNumbe
– getScreenPixels pic.twitter.com/9A8UhsOXae

One plus soon responded in an official forum, denying the claim that the keywords were used to filter out data that was not uploaded.
