Abstract
Cell phones and other handheld devices incorporating cell phone capabilities (e.g., Personal Digital Assistant [PDA] phones) are ubiquitous. Rather than just placing calls, most phones allow users to perform additional tasks, including Short Message Service (SMS) messaging, Multi-Media Messaging Service (MMS) messaging, Instant Messaging (IM), electronic mail, Web browsing, and basic Personal Information Management (PIM) applications (e.g., phone and date book). PDA phones, often referred to as smart phones, provide users with the combined capabilities of both a cell phone and a PDA. In addition to network services and basic PIM applications, one can manage more extensive appointment and contact information, review electronic documents, give a presentation, and perform other tasks. All but the most basic phones provide individuals with some ability to load additional applications, store and process personal and sensitive information independently of a desktop or notebook computer, and optionally synchronize the results at some later time. As digital technology evolves, the existing capabilities of these devices continue to improve rapidly. When cell phones or other cellular devices are involved in a crime or other incident, forensic examiners require tools that allow the proper retrieval and speedy examination of information present on the device. This report provides an overview on current tools designed for acquisition, examination, and reporting of data discovered on cellular handheld devices, and an understanding of their capabilities and limitations. It is a follow-on to NISTIR 7250 Cell Phone Forensic Tools: An Overview and Analysis•, which focuses on tools that have undergone significant updates since
that publication or were not covered previously.
