If you are still analyzing pay telephones, then you are existing in ancient history. As we enter the next decade of the twentieth century, a lot of folks are using mobile phones – including the suspects that we examine.
As mobile telephones have gotten more advanced, it does not make a great deal of sense any longer to just call the devices “phones.”. In fact, the title “mini computer” would be a more appropriate title for these mighty little communication devices. Smartphones like the blackberry and iphone are notably influential sources of forensic evidence.
Ordinary belief among many – in particular smaller – police departments is that analyzing cell forensics is more technological than they have the time or the personell to handle. But this is simply 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 forensic data out of mobile phones. This development 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 device forensics in this article. In another article on Mobile Forensic Extraction, we discuss mobile investigative extraction tools.
Though it may seem to be a trivial question if you have any experience with handset forensics|mobile device forensics[/spin], no double several police department cops might want a definition for mobile forensics forensics|mobile device forensics[/spin]. Here is a good definition:
The removal and investigation of data from mobile phones seized by detectives.
To aquire these cell telephones from individuals of interest, they are generally captured during an arrest or when a search warrent is exercised. The way to legally acquire mobile phones for cases is not the point of this article – we have to presume that you are rather familiar with the fundamentals of criminal justice. Consult your defense attorney to make certain that you acquire the telephones corectly. Keep in mind that the process from start to finish needs to be documented for court.
Cell forensic data includes:
- Emails ( in the case of smartphones)
- Address books
- Pictures (occationallly together with geo-data!)
-Text messages
-Call Detail Records (aka numbers called and numbers calling)
The importance of cell [spin]phone forensics|mobile device forensics[/spin] is rather apparent.
They can without difficulty produce the next lead of your investigation, but they also give valuable perspective for your individuals of interest. Who is called most often by your subject? Who is receiving his emails? What persons are a part of his inner group of co-conspirators?
Simply receiving data off of a handset, however, is not enough. You need a way to examine the information. It is not uncommon for forensic crime analysts to rave about the number of files they are able to pull off a particilar telephone. However, the only point of pulling data from a telephone is to generate leads and the resulting evidence with ANALYSIS.
In another article later in this series on Cell Forensics Analysis Software, we will hit on some cell forensic analysis system that turns the information from the extraction devices (like the Cellebrite, Secureview, or XRY) and actually turns it into actionable intelligence automatically.
