Focus: Although smartphone forensic concepts are similar to those in digital forensics, smartphone file system structures differ and require specialized decoding skills to correctly interpret the data acquired from the device. Today you will apply what you already know to smartphone forensic handling, device capabilities, acquisition methods, and data encoding concepts of smartphone components. You will also become familiar with the forensic tools required to complete comprehensive examinations of smartphone data structures. Malware affects a plethora of smartphone devices. This section will examine various types of malware, how it exists on smartphones, and how to identify it.
The existence of malware on smartphones is a reality that all examiners today must address. Often, the only question relating to an investigation may be "was this smartphone compromised, how, and what can you do to fix it?" It is important for examiners to understand malware and how to identify its existence on the smartphone.
Smartphones will be introduced and defined to set our expectations for what we can recover using digital forensic methodologies. We review the properties of Flash memory in mobile devices and demonstrate the pros and cons from a forensic perspective. We provide approaches for dealing with common challenges such as encryption, passwords, and damaged and devices. You will learn how to process and decode data on mobile devices from a forensic perspective, and you will learn tactics to recover information that even forensic tools may not always be able to retrieve.

|Press & Reviews|
"I think anyone that claims to be a mobile device "expert" should be required to take this course. Not knowing this information has severely hindered investigations in our lab!!!"
"If you want to prepare the inevitable considering taking FOR585."
"This is the most advanced mobile device training that I know of and is greatly needed. It is currently the only course being taught at this level!" Scott McNamee DoS/CACI
"As an experienced user of the tools, I found FOR585 very instructional on how an dwhy these tools give the results they do during an examination." - SA Charles Cox, FBI CART
"FOR585 is the best out there." - Andy Nind, British Army
"What didn't I find?" That is one of the most relevant questions in any forensic examination. By just running forensic tools, even multiple tools, you still can't answer that simple question. SANS 585 doesn't just teach you how to examine a device in specific tools, it teaches you the mindset of examining mobile devices. It is a constant reminder that an examiner needs to know what to look for, not just where to click. For those new to mobile forensics, it is a fantastic starting point that will help examiners transition into non-computer forensics. For those with previous mobile device experience it can reveal what tools and other methods may have missed when examining different families of mobile devices."-SANS FOR585 Student
