Query: FirmwareDroid: Security Analysis of the Android Firmware EcoSystem   The Android Open Source Project (AOSP) is probably the most used and
customized operating system for smartphones and IoT devices worldwide. Its
market share and high adaptability makes Android an interesting operating
system for many developers. Nowadays, we use Android firmware in smartphones,
TVs, smartwatches, cars, and other devices by various vendors and
manufacturers. The sheer amount of customized Android firmware and devices
makes it hard for security analysts to detect potentially harmful applications.
Another fact is that many vendors include apps from 3rd party developers. Such
bloatware usually has more privileges than standard apps and cannot be removed
by the user without rooting the device. In recent years several cases were
reported where 3rd party developers could include malicious apps into the
Android built chain. Media reports claim that pre-installed malware like
Chamois and Triade we able to infect several million devices. Such cases
demonstrate the need for better strategies for analyzing Android firmware. In
our study, we analyze the Android firmware eco-system in various ways. We
collected a dataset with several thousand Android firmware archives and show
that several terabytes of firmware data are waiting on the web to be analyzed.
We develop a web service called FirmwareDroid for analyzing Android firmware
archives and pre-installed apps and create a dataset of firmware samples.
Focusing on Android apps, we automated the process of extracting and scanning
pre-installed apps with state of the art open-source tools. We demonstrate on
real data that pre-installed apps are, in fact, a a threat to Android's users,
and we can detect several hundred malware samples using scanners like
VirusTotal, AndroGuard, and APKiD. With state of the art tools, we could scan
more than 900000 apps during our research and give unique insights into Android
custom ROMs.
