Book Review: “Cell Phone Investigations” by Aaron Edens

Until now, if you wanted to learn all about cell phone investigations you would be cobbling together knowledge in scavenger hunt fashion. Your trek might include:
  • seminars, given by a few universities and forensic software vendors; 
  • technical law enforcement newsgroups where tips are swapped; 
  • articles and white papers ferreted out on a topic by topic basis;
  • and a lot of personal trial and error.
Times have changed.

All the basics one needs to know is clearly laid out in this book. Each chapter is packed with many interesting sub-chapters like: caller ID spoofing, cell site dumps, storing and preserving evidence. The Table of Contents shows the important bases covered…

  • Chapter 1: Search Warrants
  • Chapter 2: Phone Records
  • Chapter 3: Tools for Examining Records
  • Chapter 4: Cell Towers and Cell Sites
  • Chapter 5: Cell Phone Forensics
  • Chapter 6: Digital Evidence
  • Chapter 7: Types of Examinations
  • Chapter 8: Using Cell Phone Forensics
  • Chapter 9: Locked Devices
  • Chapter 10: iPhone Backup Files
  • Chapter 11: Sample Search Warrants
  • Templates
  • Appendix

Law enforcement investigators will particularly appreciate Mr. Edens’ street tips. 

Example 1: Arresting officers need training when it comes to electronic evidence collection. If 12 gang members are arrested you are likely to get a bag o’ phones without knowing which suspect owns what phone. “Without a doubt if they had seized 12 firearms the process would have been completely different. The firearms would have been photographed in place to precisely document the location at which they were found, and to establish dominion and control.”

Example 2: The five errors law enforcement officers make when using cell site information. Most of these apply to private investigators and attorneys as well. “Investigators will commonly refer to the cell phone and the target of the investigation interchangeably. I strongly recommend you avoid this dangerous habit,” and goes on to explain the important reason why.

Strip away the some of the law enforcement only information and you have an excellent book for the private sector with fascinating CSI tidbits tossed in. Say the phone you want to examine is soaked in blood or some other yuck biohazard. What can / should you do? Hint, don’t try cleaning it with soap, water and your electric toothbrush. Nah, I’m sure you knew better about the toothbrush. Try alcohol in an ultrasonic tub instead.

New devices like smart watches, and breadcrumbs from the Internet-of-things, are bringing new opportunities and challenges continually. Updates and revised editions of this book are to be expected, and a companion web page with late breaking news would be a welcome addition.

Having all the information in one place has been accomplished very well. Transferring the knowledge to the reader – easily – will take a little more finesse.

In its current form, Cell Phone Investigations is a tiring read. Some basic visual communications tenets were overlooked. Lines of type stretch across 6.5 inches of an 8.5 inch page, averaging about 113 characters per line. This makes focusing difficult. To compound the visual felony the text is entirely sans-serif type, making reading even more challenging. The solution for future editions is simple. Use two columns per page, with no more than 55-65 characters (including spaces) per line. Use serif type for the text. Save the sans-serif type for titles and headlines. These typographical shortcomings should not deter you from this edition, however. Just expect you won’t be reading this cover to cover in one sitting.

“Cell Phone Investigations” (238 pages) is perfect for law enforcement, attorneys, and students entering either field. If it was written only for private investigators, security directors and people who deal with the public answering questions about cell phones, it would just be fewer pages. In the end, all groups get the education they need in an accurate, well written, well organized manner, with illustrations and charts appropriately sprinkled throughout. ~Kevin

Spybusters Tip # 823 - Two Wiretaps You Can Find Yourself

Imagine this...
• Partners in a business have a falling out, but one of them seems to know everything.
• The founder of a growing company is forced out, but still seems to know everything.
• A divorce is pending. The husband moves out, but still seems to know everything.

Q. "How could this be?"
A. The other person may have purchased a legal wiretap... from the phone company!
(The act of eavesdropping is still illegal, however.)

Q. "What can I do?"
A. Pick up a different phone and search for it.

Call your local phone company business office. Review your account. Specifically, look for an OPX or an FX, which your "partner" may have added.

An OPX is an Off Premise Extension. It is just what it sounds like; an extension phone, located in the same area served by your exchange, but somewhere else.

An FX is a Foreign Exchange. Same as an OPX, but located in some other exchange or area code.


Bonus Spybusters Tip...
Q. Not receiving all you calls? 
Are people leaving voice mail messages, but you never hear them, or they show up late? Check your account for Remote Access to Call Forwarding. This feature allows the other person to redirect your calls, at will, from anywhere, to anywhere. 

Once engaged, they can answer your customer's calls - using your company name, or send them to their own voice mail (using a recording of your voice mail greeting). They may even selectively transfer these intercepted messages back to your voice mail - possibly edited. (Think Mission Impossible).

Double Bonus Spybusters Tip...
Double check the number of phone lines listed as coming to your address. This should exactly match the number of lines you think you have. Any extras? Call a qualified TSCM specialist for a sweep. 

Triple Bonus Spybusters Tip...
Once you have sorted all this out with your local phone company business office, ask them to "flag" your account. This means they will only discuss your account, and make changes, if they are given the correct password. Pick a good password. Don't use "Afganistan Banana Stand," that's mine. Don't tell anyone what your password is.

Hairdresser Makes Man Harried

Can you solve this mystery?
Police in Germany helped a man solve a mystery that had been bugging him for over two years. The phone would ring and the man did not recognize the number so he had the number blocked.


After paying to have the number blocked for a while he stopped paying for the blocking service and the mystery started all over again. (answer)

Make Caller ID Lie For You

Keep your phone number private whenever you make or receive calls. A new service called Vumber does it for you.

In addition to privacy you can get anonymity, too. Vumber is like Kleenex, disposable. Change numbers whenever you want. Be in any Area Code you like.

"It’s your anyphone, anytime, anywhere phone number that keeps your identity private – until you decide it not to be.

A Vumber is a number from any area code you want, linked to your home, cell, or work phone. When someone calls your Vumber, Vumber lets you control how you handle the call: you can a) answer it; b) send them to VumberMail; c) give them a busy signal; d) tell them the number is out of service; or e) play them a custom message you create.

It provides unequaled privacy protection when anyone calls your Vumber, and when you call anyone. And it’s not limited to a pre-defined one-to-one calling relationship like you sometimes see out there – it is as simple as having another phone number. Even simpler.

You can call “from” your Vumber, too..." (more)

The flip side... Your Caller ID display is no longer trustworthy. But hey, it never was anyway.

Turned 'off' Cell Phone Calls Owner ...Whoo Hoo, Whoo Hoo Hoo

Ed Ravin reports...
"A friend of mine uses Vonage (VoIP) for her primary phone line. Their VoIP system gave her a nightmarish experience during the wee hours of December 15.

The problem started around midnight - her VoIP phone rang, and caller-ID showed it was a number local to her area, but she didn't recognize it. She answered, but there was no one on the line. Her phone rang again several minutes later - same caller-ID, again no one there. And a few minutes later, the phone rang again, same caller-ID, same nobody there.

Then her cell phone rang. The cell phone's caller-ID showed the same phone number as her VoIP phone did. Again, the line was dead when she answered it. Twice more in short order, the phantom caller rang her cell phone.

Now wide awake and rather disturbed, she went to her computer to look up the phone number of her putative persecutor. Google helpfully provided a reverse directory lookup - to a person with an Arabic-sounding name that she did not recognize. With the help of Mapquest, she found out that this unknown person lived only a few miles from her. Worried and feeling vulnerable, she was unable to get to sleep, thinking that a strange person in the neighborhood was calling both her home phone and cell phone for no apparent reason.

At 3 in the morning, her VoIP phone rings again - this time, the caller-ID says that her own cell phone is making the call! But the cell phone is turned off and is sitting on her nightstand. She finally smells the rat, and at 4 AM calls the Vonage customer support line After a 30 minute wait, a polite but difficult-to-understand person explains that Vonage has been experiencing a problem with "phantom calls" and it should be resolved soon.

My friend had her Vonage account set up so that if her VoIP number was down, it would automatically forward calls to her cell phone. So Vonage's software PBX had her cell phone number on file, and it apparently went haywire and began placing calls to numbers in its database, and using other numbers in its database as the caller-ID.

The biggest risk here is believing what you see on your caller-ID display. Using computerized tools to compound your error and jump to the wrong conclusions is a close second. Then there's the well-known "mission creep" risk, where data supplied for one purpose is (mis) used for another. Even though the misuse was unintentional, it's a stark reminder that phone numbers are a special kind of data with real-world implications, especially when in the hands of buggy software that can make phone calls. ...from Risks-Forum Digest - Volume 25 : Issue 02
