As the core platform quickly matures and continues to be provided free of charge, carriers and hardware vendors alike can focus their efforts on customizations intended to retain their customers. History of Android For over three decades, companies have invested significant resources into research and development of handheld computing devices in the hopes that they would open new markets. As with traditional computers, the hardware components central to building such devices have advanced significantly and now provide a small, though powerful, mobile platform for handheld computers. His previous company, Danger Inc. This mobile operating system, DangerOS, was built using Java. It provided a software development kit and had some of the features found in current smartphones.
This paper takes the position that the currently used, well accepted practices for monitoring, debugging and post mortem crash analysis are insufficient to deal with the threat of compromised IOS devices.
It sets forth a different method that reduces the requirement for constant logging, favoring on- demand in-depth analysis in case of suspicion or actual device crashes. Presentation gives an overview of Android, explains how to root phones, and extract data from a phone once you have superuser access.
Gubian, P. This is especially true when in a digital investigation the examiner has to deal with corrupted compressed files, which have been gathered in the collection phase of the investigative process. Therefore, in the computer forensic field, data recovery technologies are very important for acquiring useful pieces of data which can become, in a court of low, digital evidence. This kind of technology is used not only by law enforcement, but also by the multitude of users in their daily activities, which justify the relevant presence of tools in the software market which are devoted to rescue data from damaged compressed files.
However, state-of-the-art data recovery tools have many limitations with regard to the capability of recovering the original data, especially in the case of damaged compressed files. Therefore, in order to deal with this issue, we have developed a new tool capable of rescuing damaged compressed files, according to the DEFLATE compression scheme, even though the header block is missing or corrupted.
This represents a new interesting opportunity for the digital forensic discipline. While cell phones are becoming more like desktop computers functionally, their organization and operation are quite different in certain areas. For example, most cell phones do not contain a hard drive and rely instead on flash memory for persistent storage.
Cell phones are also designed more as special purpose appliances that perform a set of predefined tasks using proprietary embedded software, rather than general-purpose extensible systems that run common operating system software. Such differences make the application of classical computer forensic techniques difficult. Also complicating the situation is the state of the art of present day cell phone forensic tools themselves and the way in which tools are applied.
This paper identifies factors that impede cell phone forensics and describes techniques to address two resulting problems in particular: the limited coverage of available phone models by forensic tools, and the inadequate means for validating the correct functioning of forensic tools Apr A Framework for Automated Digital Forensic Reporting , Lt. Paul Farrell, Master's Thesis, Naval Postgraduate School, Monterey, CA, March Forensic analysis is the science of finding, examining and analyzing evidence in support of law enforcement, regulatory compliance or information gathering.
Today, almost all digital forensic analysis is done by humans, requiring dedicated training and consuming man-hours at a considerable rate. As storage sizes increase and digital forensics gain importance in investigations, the backlog of media requiring human analysis has increased as well.
This thesis tests today's top-of-the-line commercial and open source forensic tools with the analysis of a purpose-built Windows XP computer system containing two users that engaged in email, chat and web browsing. It presents the results of a pilot user study of the PyFlag forensic tool. Finally, it presents a technique to use software to do a preliminary analysis on media and provide a human readable report to the examiner.

History of Android For over three decades, companies have invested significant resources into research and development of handheld computing devices in the hopes that they would open new markets. As with traditional computers, the hardware components central to building such devices have advanced significantly and now provide a small, though powerful, mobile platform for handheld computers. His previous company, Danger Inc. This mobile operating system, DangerOS, was built using Java.
It provided a software development kit and had some of the features found in current smartphones.
In , Rubin left Danger and tinkered with several new ideas. He again returned to smartphone development and teamed with several engineers from past companies. The company Rubin formed in was called Android, Inc. While the team began development, Rubin was actively marketing Android to both potential investors and wireless carriers. One of the companies he spoke with was Google, who subsequently acquired Android in July The acquisition, combined with new patents and services involving mobile and a large bid for wireless spectrum, fueled significant speculation that Google was developing their own smartphone and perhaps was aiming to be a full wireless carrier.
However, on November 5, , Andy Rubin announced a more ambitious plan on the official Google blog Official Google blog, n. It includes an operating system, user-interface and applicationsdall of the software to run a mobile phone, but without the proprietary obstacles that have hindered mobile innovation.
Through deep partnerships with carriers, device manufacturers, developers, and others, we hope to enable an open ecosystem for the mobile world by creating a standard, open mobile software platform.
We think the result will ultimately be a better and faster pace for innovation that will give mobile customers unforeseen applications and capabilities.
One week later, Google released an early look at the Android software development kit SDK to developers. In August , Google announced the availability of the Android Market where developers could upload their apps for mobile device owners to browse and install. The initial release did not support paid apps. However, that feature was added in early Since inception, the Android ecosystem has grown significantly and is comprised of diverse groups of contributors.
Table 1. Open Handset Alliance The Open Handset Alliance OHA is a collaboration among mobile technology companies including wireless carriers, handset and component manufacturers, software developers, and other support and integration companies. The alliance, established on November 5, , originally had 34 members.
However, by January there were nearly 80 members. Some have complained that the alliance is simply a marketing technique that offers little value to the members or consumers. However, new members have joined throughout and the OHA will undoubtedly continue well into the future. The members, as of Table 1.
Android launched Android Market announced Android 1. Android Features While we explore the various Android device types more in the next chapter, there are several features common to most Android devices that we can discuss here. Regardless of the venue, the ability to be online is a core feature of any Android device. Many of the devices are indeed smartphones and thus support sending and receiving phone calls, text messages, and other services found on cellular networks.
Interacting with the device is typically via a touch screen, but many devices also allow for keyboards or other buttons, which support user interaction. A second core feature of Android devices is the ability to download and install applications apps from the Android Market. This is a primary feature to many users because it allows them to extend the functionality of the device.
These apps also typically happen to be a rich source of information for forensic analysts. The final core feature is the ability for users to store their data on the devices.
This, of course, is the basis for the forensics work covered in detail in this book. Most Android devices come with some on-device storage using flash NAND memory as well as an external SD card that is portable and intended to store larger amounts of data.
Supported Cellular Networks As smartphones are the largest category of Android devices, it is important to understand the various cellular technologies Android currently supports. GSM is the most widely used and supported cellular system with excellent support throughout the world. It is popular in the United States, but less so around the world.
Major carriers include Verizon Wireless, Sprint, U. Cellular, and Cricket Communications. Softbank Mobile Corp. Cypress Semiconductor Corp. MediaTek, Inc. Android platform Table 1. ST-Ericsson Synaptics, Inc. Texas Instruments Inc. Via Telecom Access Co. Cooliris, Inc.
Google Inc. Accenture Aplix Corp. So why did Google give Android away for free?
Cell phones are the most popular consumer device, numbering over 4 billion, so by providing an advanced mobile stack at no cost, Google believes they are fulfilling the universally accessible portion of their mission. But, obviously there must still be some benefit for Google. Krazit, n. One of the criticisms of Android is that the market is now highly fragmented with different versions and variations of Androidda direct result of how Google releases Android to the manufacturers.
This is in contrast to other devices, such as the iPhone where Apple has total control over the hardware and OS and significant influence over third-party application. Rubin defends this model, however. In the same interview, Rubin further commented on this aspect Krazit, n.
You can have spurts of innovation. So by creating a mobile OS that meets the demands of the consumer as well as the needs of the manufacturers and wireless carriers, Google has an excellent distribution platform for their revenue-generating search and advertising business. Apps One important way by which Android supports innovation beyond the core mobile stack is by enabling the development and distribution of third-party apps on Android.
As of January , over , Android apps have been developed. This, of course, is similar to the strategy Apple developed. However, there are key differences in their approach. Apple maintains tight control over their App Store, Android platform requiring developers to submit to a sometimes lengthy review process and providing Apple with the final approval for an app. Apps can be denied based on a number of criteria, most notably if they contain any content Apple feels is objectionable.
Google, on the other hand, requires very little review to publish an app in the Android Market. While Google has the ability to ban a developer, remove an app from the Android Market, and even remotely uninstall apps from Android devices, in general their approach to app management is hands off. The N1 was developed by HTC and, by all accounts, was an ideal model for how manufacturers should develop their phones. The processor was extremely fast 1 GHz , it was running the latest version of Android, and it had innovations such as three microphones which survey background noise and blend your voice to create the most clear conversation possible.
The N1 was sold directly by Google and was sold unlockedda move many analysts saw as a direct challenge to the carrier lock-in model where customers must sign a two-year agreement to get a discount on the device. The N1 was also available through T-Mobile for a reduced price, provided the user signs an extended contract.
In the end, the sales for the N1 were not overwhelming and there was speculation that Google failed in their implementation Fig. However, at the time, Google was also trying to demonstrate how they believed an Android phone should be released and maintained. To the surprise of many, one year later Google released the Nexus S manufactured by Samsung, shown in Fig. One interesting feature of the Nexus S was that it ran on Android 2.
