Why Mobile Forensic Are Important For Analysts

If you are still investigating pay telephones, then you are living in antiquated history. As we enter the next ten years of the twentieth century, a lot of people are using mobile telephones - including the criminals that we analyze.

As mobile telephones have evolved, it does not make a great deal of sense anymore to just call the devices "telephones.". In fact, the title "mini computer" would be a more appropriate title for these mighty little communication devices. Devices like the blackberry and iphone are exceptionally powerful sources of investigative evidence.

Ordinary conviction among most - especially smaller - police agencies is that investigating cell forensics is more scientific than they have the time or the personell to handle. But this is just not the situation. Take a look abroad: the UK, and other nearby Eurpean nations, are far more advanced that the United States when it comes to squeezing investigative information out of cell phones. This progression was not that tricky; it really only took a willingness to recognize that mobile device forensics are valuable for investigations. We will discuss importance of mobile forensics in this article. In another article, we discuss cell forensics acquisition tools.

Though it may seem to be a trivial question if you have any experience with mobile forensics, no double several agency cops might want a definition for cell forensics. Here is a good definition:

The removal and investigation of information from cell telephones seized by detectives.
To aquire these cell telephones from individuals of interest, they are generally aquired during an arrest or when a hunt warrent is exercised. The way to legally get hold of mobile phones for investigations is not the point of this editorial - we have to assume that you are somewhat familiar with the basics of criminal justice. Consult your defense attorney to guarantee that you acquire the smartphones corectly. Take into account that the method from start to finish needs to be documented for court.

Mobile forensic data includes:

- Emails ( in the case of smartphones)
- Address books
- Pictures (occationallly including geo-information!)
-Text messages
-Call Detail Records (aka numbers called and numbers calling)

The importance of mobile device forensics is rather clear.

They can without difficulty generate the next lead of your analysis, but they also provide valuable background for your targets. Who is called most often by your target? Who is receiving his emails? What individuals are a part of his inner group of co-conspirators?

Simply getting data off of a handset, however, is not enough. You need a way to analyze the information. It is not uncommon for forensic law enforcment to rave about the number of files they are able to pull off a particilar telephone. However, the only point of extracting data from a telephone is to generate leads and the resulting evidence with ANALYSIS.

In another article later in this series, we will hit on some cell forensics investigation software that turns the information from the aquisition devices (like the Cellebrite, Secureview, or XRY) and actually transforms it into useful intelligence automatically.
