There has been a lot hype and some misleading statements about it so here we go: Since we got those pre-prod samples a few weeks ago, a lot of work has been done to improve heat dissipation a graphene heat sink is now in place inside the watchwater resistance and signal quality. The user interface has also been tweaked with many improvements to improve usability and speed.
Modern digital forensics processes differentiate collection and analysis, with collection ideally only occurring once and the subsequent analysis relying upon proper collection.
The major contribution of this paper is a general process for data collection of Android devices and related results of experiments carried out on several specific devices.
Not only do mobile phones employ a diversity of cables, interfaces and form factors, but the devices have unique software, memory layouts and storage techniques. This amazing diversity has led to the digital forensics practitioner being assaulted with complex kits containing a plethora of cables and data collection techniques .
S mobile consumers owned smartphones, with all the the top ten selling phones being smartphones . Nandwrite android watches existing manufactures produce Android based devices and all major carriers sell said devices.
The ubiquity of devices utilizing the Android framework facilitates exploiting common properties to minimize the diversity required of digital forensics tools while simultaneously maximizing the potential for sound data collection.
To our knowledge, this paper represents the first work done toward a general collection method for Android based devices. The array of mobile phones and pricing plans available today is indicative of the wide desires and needs of the user base, and must be coped with by digital forensics practitioners.
Willassen, inoutlines many items of interest for GSM based mobile phone analysis: In the same author explored collection methods for commodity mobile phones, in particular the use of physical access to the circuit board interface e.
Also inCasadei introduced a live collection technique, dubbed SIMbrush, facilitating entire file system collection for unprotected files particular to SIM devices .
InAl-Zarouni investigated the use of mobile phone flashing tools in regard to digital forensics . The author concluded that while forensically sound, the primary use of the tool was to write to, not read from, the device.
Read capability varied widely across device brands and models and consequently flashing tools may prove problematic as a means of collection. Also inMokhonoana and Oliver detailed a collection method for Symbian OSv7 devices , and Distenfano in explored a Symbian OSv8 collection method in .
Indeed, due to the vast diversity in the mobile space, it is very common for research to be scoped to particular operating systems or hardware platforms such as Blackberry , CDMA , iPhone 3Gs , Nokia , etc. The demand for mobile forensics combined with the diversity of the mobile device market has led to a myriad of mobile forensics tools.
InAyers et al. The same year Williamson et al. InJansen and Ayers again compared existing tools on contemporary mobile phones and collected their work into a NIST report .
Later, in  Yates notes the diversity of the mobile device market and the associated complexity presented to a practitioner attempting to select the appropriate digital forensics tool. Just the comparison papers mentioned here cover: Rooting is common vernacular for gaining administrative root access to a device where the user is intended to only have unprivileged access, such as a mobile phone.
We explore the rooting further in section V-B. InThing et al. This technique is often used for debugging  but often repurposed for malware analysis . For performance reasons, developers can create software that runs natively on the hardware avoiding overhead induced by the JAVA virtual machine.
The SDK makes high level software development very approachable by providing features such as a full featured emulator, an Eclipse the preferred Integrated Development Environment add-on specific to Android and a special Android Debug Bridge adb to enable debugging information from an emulator instance or USB connected physical device .
Using the feature, the developer can not only observe debug information, but also perform an assortment of other actions such as installing software bypassing the Market application reboot the device, and even open an interactive remote shell.
Note that adb is typically not enabled in production devices and must be enabled by the user1. For low level experimentation, Android is open source, the code can be easily obtained and compiled .
Some vendors, such the manufacturer of the G1 phone: HTC, embrace developers with a rich web site providing not only documentation but also pre-built tools and even phone images .
Contrarily, other manufactures never release such information to the public and protect phone images closely as coveted intellectual property. Such a collection would strictly contain less information due to the inaccessibility of unallocated storage locations and permissions enforced by the running Android system the adb process does not execute with root privileges.
Here we enumerate desirable criteria for the collection process. Data storage locations that house user data are of primary importance, as this type of data is likely to be more valuable to investigation than system files common to many devices.
This view does not completely discount the collection of storage less likely to house user data, it only places more value on user data.
The ability to capture system information may, in fact, be very useful in tandem with user data. Though quite likely less common, particular cases may dictate that cache information, firmware and kernel crash information be critical.
Data should be collected as atomically as possible with respect to the device being collected. If a device is currently executing instructions and manipulating storage the collected state may not be a valid.Sep 10, · xda-developers Chef Central Android [ FIX ] Nand write start fail on odin by ErickNoz XDA Developers was founded by developers, for developers.
