Legal Considerations

Recent Case Law Training necessary around preservation and

analysis of electronic data Preservation - Must be Defensible …Have a documented

tracking / acquisition procedure. Analysis - Subjective or Objective? … Just another technical

skill set … but investigation is not same as processing Platform variations can make substantial difference

Practice tips Tip - Preservation may be prudent or required … Analysis

may be unnecessary Tip - Notes Notes Notes and a written report or memo to file

always Tip - Magnum Force “A man’s got to know his limitations …”

Harry Callahan.

The Current Landscape

Mobile device data is the new email Yet it is often still possible for parties to

agree to ignore mobile device data Prior to reaching agreement, preservation

obligation must be considered Privacy considerations are commonly

raised Stored Communications Act may be

asserted as bar

Quon v. Arch Wireless, 9th Cir, 2008

Sherriff’s department contracted with third party for text message service

Department reviewed text messages obtained from provider to determine reason for overages

Found sexually explicit material and attempted to discipline employee

Court held that Stored Communications Act applied

Employee had reasonable expectation of privacy Supreme Court has granted cert

Flagg v. City of Detroit, ED MI, 2008

Allegedly botched murder investigation Relevant text messages to/from city

employees including mayor Court held that Stored Communications

Act could not be used to prevent discovery of relevant text messages via subpoena to carrier

Text messages were effectively in “control” of City even though they had to be obtained from carrier

Page 10: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

Southwestern Mechanical Services, Inc. v. Brody, MD FL, 2009

Sanctions were imposed for failure to preserve data on Blackberries

For key time period, devices were not synched with server

Court focused on email, but also text messages, contacts, calendar items, telephone usage records

Page 11: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

Southwestern – The Backstory

Theft of trade secrets by employees who left to join competitor

Court issued TRO requiring return of all information and property to former employer

Forensic exam showed that data had been wiped from Blackberries used by two former employees

Page 12: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

What’s next

Device technology undergoing rapid improvement

Device usage is increasing and supplanting use of traditional computers

Counsel and courts are becoming more aware of the availability of this data

Forensics tools are improving and costs are coming down

Page 13: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

How do we predict trends?

Courts will borrow from experience in law enforcement related matter

Courts will be influenced by frequent use of mobile device data in family law disputes

A few prominently reported decisions will result in rapidly changing expectations

Think the unthinkable

Real World Challenges with Mobile Devices

Page 15: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

Practice Tips

Examples of cases where mobile devices are necessary. (regulatory matters, transferring IP to devices)

Regulatory Investigation - Blackberry E-Mail, IM and SMS Messages validate a pattern and specific instances of ‘leakage’

FCPA Internal Investigation - Overnight Blitz 48 computers and 50 Cell Phones Forensically preserved

ITAR - Multi-Platform Mess during compliance audit Identify relevant information through custodian

interviews Analyze the information you have collected to

determine if there are “gaps”

Know When to Say “When”

Risks of DIY Mobile Device Capture Forensic Tool Spiral - Versions / Functions / Validation

/ New Platforms Reference Materials (Data Sets / Measurement … not

just reference as in Manuals) Sample Size - results and reporting inconsistent on

different platforms and tools Budget and Time Boundaries Cost Recovery of DIY You may not like what you find …

Page 17: Mobile Devices Concerns with Forensic Capture and Analysis of Portable Data

Know When to Say “When”

Risks of DIY Mobile Device Capture Cell Phones are like Ogres … Parfait / Onions / Layers

… (Live Data / Deleted Data / Data Fragments / Unallocated Data / Flash Data / Raw Bytes and oh gosh Device Redundancy)

Economist time … on the other hand, if SMS and JPG / DOC / XLS / PPT / ETC Files are all you seek, this may be easy.

Work directly with technical investigators and communicate the issues of the case

Understand the client’s infrastructure and messaging systems and determine the relevancy of the data on the mobile device (cost benefit analysis)

Understand limits of current technology to preserve and analyze data from these devices

Technical Considerations

General Methods to handle capture of mobile devices?

Known tool sets for handling mobile devices Options, risks and benefits of mobile devices? How effective is the technology for forensic

capture? How far behind is it? For example, how do you

handle a Droid vs. a mobile device How much residual data, such as deleted data

or internet activity is on a device and how much can be captured and analyzed?

“Isn’t it all on the server?”

Technical Considerations

Most difficult PDAs to capture from Use of social networking tools from PDAs

and developing strategy Cost vs. value of analysis
