The Company You Keep: Mobile Malware Infection Rates and Inexpensive Risk Indicators
Hien Thi Thu Truong,Eemil Lagerspetz,Petteri Nurmi,Adam J. Oliner,Sasu Tarkoma,Nadarajah Asokan,Sourav Bhattacharya +6 more
TL;DR: This paper presents the first independent study of malware infection rates and associated risk factors using data collected directly from over 55,000 Android devices, and indicates that the application set does serve as an inexpensive method for identifying the pool of devices on which more expensive monitoring and analysis mechanisms should be deployed.

The company you keep: mobile malware infection rates and inexpensive risk indicators
Hien Thi Thu Truong,Eemil Lagerspetz,Petteri Nurmi,Adam J. Oliner,Sasu Tarkoma,Nadarajah Asokan,Sourav Bhattacharya +6 more
TL;DR: In this article, the authors present the first independent study of malware infection rates and associated risk factors using data collected directly from over 55,000 Android devices and find that the malware infection rate in Android devices estimated using two malware datasets (0.28% and 0.26%), though small, are significantly higher than the previous independent estimate.
