When it comes to IT security, our computers aren’t the only thing vulnerable. Almost everyone these days has a cell phone, and a cell phone can be hacked too.

One way to infect someone’s cell phone is with a malicious program called FlexiSPY. Here’s how it works. Let’s say that Dave, our company president, wants to follow up a little bit on one of his senior managers, Greg, and find out what he’s up to. Dave would simple go to Greg sometime and say, “Greg, do you mind if I borrow your mobile phone? Mine’s not working and I want to check in with my family.” And Greg says, “Sure, no problem.”

So Dave takes his phone. Now Dave has already been to FlexiSPY, and they’ve already given him the instructions of how to infect Greg’s phone with a little virus by simply visiting a web site URL. So Dave does that. He acts like he’s dialing the number, and then just to make it look good, he says into the phone, “Yeah, hi. I was just checking in. Is everything okay? Oh yeah, Greg loaned me his phone. He’s a great guy. Okay. I’ll talk to you later. Bye.” Then Dave hands Greg his phone back.

Meanwhile, Greg thinks everything is just dandy. He loaned his boss his phone and he’s a good guy. But now, any phone calls that Greg places or receives, Dave is going to get a report of who the other party is, what their phone number is, and how long they were on the phone. All that information is available to Dave for just $49.95.

Now, if Dave decided to splurge and spend $149.95, he can remotely activate the microphone on Greg’s phone and actually listen in on Greg’s activities any time Greg’s phone is turned on. So if Greg is at home tonight with his family, Dave could listen to their conversation at the dinner table. If Greg is in a closed meeting, Dave could listen to the closed meeting. Essentially, Dave could hear anything going on in Greg’s life, as long as his phone is turned on.

The CIA knows what a serious danger this technology is. In fact, the CIA is very concerned that this spying technology might get on the cell phones of some of the Chief Justices of the Supreme Court or other high-ranking government officials. If that were to happen, it would really undermine the security of the United States of America.

Therefore, never hand your phone to anyone. If someone asks me to borrow my cell phone, I say, “Sure. But I’m going to dial your number, and I’m going to stand two inches from your face the entire time you have the conversation.”

At that, the person who asked to borrow my cell phone usually replies, “Never mind.”

If you have recently handed someone your cell phone to use and are wondering if some sort of spying device is on your phone, you could have your IT professional examine the phone. Or, if your phone is getting out of date anyway, now might be a good time to trade in your phone for a new one. You can keep the same phone number, since the virus affects the phone itself and not the phone number.

If you ever look at your phone and see the screen says that the phone is “connected” or “in use” when you didn’t place a call or answer a call, then this may indicate that you have some sort of phone spyware on it. Unfortunately, most people don’t look at their phone when they’re not using it. They just leave it in their belt clip, purse, pocket, in a desk drawer, or on a table.

You would also see tell-tale signs of someone spying on your calls on your phone bill. But not everyone examines their bill, and some people never even see their bills if they use a bookkeeper to mind their finances.

If you have the right tools, you can figure out if something was loaded onto your phone. One company called Trust Digital makes a very nice central management tool to audit, manage, and protect all of your phones and PDA’s in the enterprise.

A common theme you will notice in this book for protecting your network is the concept of “Central Management.” What’s that? Well, ask any IT professional, and they’ll tell you that one of the worst things in our career is when we have to change something on all the company’s computers. It doesn’t matter if you have five computers, fifty computers, five hundred computers, or more, that’s way too much work to visit each computer, phone, or PDA, individually. We want to be able to manage things centrally.

Today’s organizations have PDAs, cell phones, Blackberries, etc. All of these devices also hold sensitive data. So what happens when one of your employees is traveling for business and accidentally leaves his mobile phone or PDA in a taxi? If you had a central management system in place, that employee would simply call the IT department and tell them what happened. Then someone in IT can make a few keystrokes on the keyboard and erase everything in that particular phone or PDA.

Now, everything on that phone gets securely erased. And when I say securely erased, that means inside that phone it’s writing ones and zeros on the data card to actually erase information. Even data forensics can’t get that data back anymore. It’s just gone.

In the event that whoever rides in the taxi next finds the phone and somehow returns it to you, your IT department can make a few more keystrokes on the keyboard and restore all the data. That sure beats having to go through a four-hour process of reloading everything.

So don’t overlook your cell phone and PDA when it comes to data security. There are tools out there that will help you-use them.

Action Item: Treat your cell phone like you treat your toothbrush. Never let anyone use it.

Over the past decade the world has seen rapid growth in cell phone users. Everyone from older adults to kids in high school seem to carry one glued to their ears, without understanding the possible health ricks associated with the use of cellular telephones.

To begin with, a recent scientific journal published in 2007 titled Long term use of cellular phones and brain tumors, concluded after assessing results from many different studies that use of cell phones for more then 10 years does show increased risk for acoustic neuroma and glioma. Adding that the risk is highest for ipsilateral exposure, meaning tumor on the same side of the brain where phone mostly held.

Research scientists behind this journal assert that most studies to date on cell phone use and brain tumors have been mostly conducted with an insufficiently long latency period. This journal report gives excellent reviews of other studies and evidence of data entry errors, systematic bias and mathematical errors within those studies.

Argument against studies which used short term recall of mobile phone use, is well argued by giving evidence that actual use of cell phones is usually underestimated by light users and overestimated by heavy users, reducing the data strength of interphone studies. In the same way, results showing increased risk for acoustic neuroma and glioma from various other studies on use of mobile phone for more then 10 years are given supporting their conclusion.

Furthermore, another study published in 2006 completed by 3 scientists in Sweden also conform a increased risk for malignant brain tumors in groups with use of cellular and cordless phones for more then 10 years. Similar to the above study, the scientists associated with this report also mention the weakness of so-far studies to be their too short a latency period.

Evidence of errors in other studies for example, Danish interphone study, in which many data entry errors had occurred due to problems in understanding words of Galioma patients due to paralysis has been well argued. They propose that their method of assessing the use of cellular and cordless phones by questionnaires to be more sensible.

Moreover, interesting evidence brought up in this journal report about a completed REFLEX-study is important to mention here. The REFLEX-study which tested for genotoxic effects in cells exposed to radio frequency electromagnetic fields at SAR (whole-body Specific Absorption Rate) levels between 0.3 and 2 watt/kg showed evidence for. Increase in single and double strand DNA breaks finding of choromosomal aberrations were observed in fibroblasts and intracellular increase of free radicals in HL-60 Cells.

Evidence from the REFLEX-study coupled with the evidence from their own study, the Swedish scientists concluded that the current allowed SAR of 2 watt/kg in Europe is inappropriate.

Conversely, it is important to make known to our readers that the maximum SAR level in United States and Canada has been capped at 1.6W/kg (FDA).

Finally, a journal published in 2007 Mobile phone use and risk of glioma is 5 North European countries, show somewhat mixed results. This particular studies results were based on combined data from Denmark, Finland, Norway, Sweden and Southeast England, where mobile phones have been widely used for at least a decade. This study looked at reasonably large group of people. Total of 2,530 glioma patients and 6,581 controls had participated in this study.

Nonetheless, it is surprising to know that their conclusions are not as clear as in previous studies we mentioned. This study claims to find no elevated risk of Glioma among groups most exposed. Neither did they find any significant association across, categories with duration of use, years since first use, cumulative number of calls or cumulative hours of use.

They also claim to find no increased risks when analogue and digital phones were tested separately. However, this study did find one set of analyses which indicates a possible connection. This connection was between, reported ipsilateral use 10 or more years ago associated with significantly increased risk of glioma and there was also an increasing tread with years since first use on the ipsilateral side.

Lastly, we recommend that consumers seek information about what SAR level their cell phone uses. SAR information is easily found in instructional materials that come with the phone or can be found on many web sites. We recommend consumers to use cell phones that operate at lowest possible value of SAR, and to try to limit the use of cell phones or invest in a hands free headset for cell phones until more absolute evidence is obtained.
