Why Mobile Forensics Are Useful For Police
Author : Rick Burton
If you are still investigating pay telephones, then you are living in ancient history. As we enter the next ten years of the twentieth century, a lot of folks are using cell telephones - as well as the subjects that we analyze.
As mobile telephones have evolved, it does not make much sense anymore to just call the devices "telephones.". In fact, the title "mini computer" would be a more suitable title for these powerful little communication telephones. Smartphones like the blackberry and iphone are exceptionally powerful sources of forensic evidence.
Widespread belief among most - especially smaller - police agencies is that analyzing cell forensics is more technological than they have the time or the people to handle. But this is simply not the situation. Take a look out of the country: the UK, and other nearby Eurpean nations, are far more advanced that the United States when it comes to extracting forensics data out of mobile phones. This development was not that challenging; it really only took a willingness to recognize that mobile forensics are valuable for cases. We will discuss importance of cell phone forensics in this article. In another article, we discuss cell forensic extraction tools.
Though it may seem to be a trivial question if you have any experience with mobile device forensics, no double several agency cops might want a definition for cell forensics. Here is a good definition:
The removal and investigation of data from cell phones seized by detectives.
To aquire these mobile telephones from individuals of interest, they are usually aquired during an arrest or when a hunt warrent is exercised. The way to lawfully attain mobile phones for cases is not the point of this editorial - we have to suppose that you are somewhat familiar with the essentials of criminal justice. Consult your defense attorney to ensure that you acquire the devices corectly. Remember 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 significance of cell forensics is quite apparent.
They can with no trouble produce the next lead of your investigation, but they also provide valuable background for your subjects. Who is called most often by your suspect? Who is receiving his emails? What individuals are a part of his core 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 investigators to rave about the number of files they are able to pull off a particilar telephone. However, the only point of extracting information from a handset is to generate leads and the resulting evidence with ANALYSIS.
In another article later in this series, we will hit on some cell forensic analysis software that turns the information from the aquisition devices (like the Cellebrite, Secureview, or XRY) and actually turns it into useful intelligence automatically.
