Barnes & Noble NOOK 7 is full of temptation. It's cheap and loaded with millions of book collections. However, a recent research reported by Linux Journal has learned that the tablet contains malicious malware capable of transmitting all user's data inside the device to a remote server in China.

What is ADUPS firmware?

ADUPS is a Shanghai-based firmware provisioning company specialized in data collections and firmware control.

ADUPS is undetectable by 'ordinary' malware scanners, according to Android Headlines. The worse thing about the firmware is that it is installed as a part of OS components and in this case, MediaTek reportedly protects the code from Google security scan.

A research by Kryptowire has found that ADUPS is capable of transmitting all users' data from text messages, installed applications to remote execution without user consent. The reported analysis has also disclosed that the firmware is included in BLU R1 HD and some of the tablets sold at US online retailers such as Amazon.

If there is anything worst, LinuxJournal has learned that Google has blacklisted ADUPS in Android Compatibility Test Suite (CTS).
