When a mobile phone becomes seriously corrupt or severely damaged, the only recourse for recovering the important data contained within is to carefully remove the memory chip and then image it onto a computer for data recovery purposes. Fortunately, there are many forms of cell phone forensic examinations that can be performed on a phone that has been impacted by accidental damage. These include data retrieval through the usage of electronic media, such as microprocessor rom, flash memory, and other storage media. However, there are other types of cell phone forensics that can also extract data from a damaged phone in some cases.
Water Damage: In many cases, water can cause major damage to mobile devices. Water can cause flash rom to malfunction, memory cards to become corrupt, and so forth. When this happens, it can be extremely difficult to recover any important data from the affected mobile device. This is one of the most common forms of cell phone forensic examination that can extract data from affected cell phones. Additionally, in cases where the damage is due to accidental deletion, which typically occurs when a cell phone is simply nudged against a soft surface, expert cell phone forensics can also perform a water extraction test on the phone to determine the exact point of impact for recovery of data.
Call Logs: Most cell phones have built in call logs that provide information about the call that was received and made by the particular mobile devices, including the date and time that the call was made, the duration that it lasted, and who the call was directed to. However, these logs can also contain a lot of useful information for forensic examination. For example, if the number in question is associated with an unknown caller, expert cell phone forensics may be able to obtain call logs or call detail information to help identify the person behind the call. Likewise, if the mobile devices are being tampered with or altered in some way, then this information will also be helpful in establishing whose phone was used.
Text Message Forensic Examinations: Similar to call history examinations, text message forensics can help establish relationships among suspects. By examining a series of different kinds of cell phone forensics examinations, such as computer forensics, a text message forensic investigation can reveal exactly what was exchanged via the cellular device. One of the most widely used methods is known as ISeparatio analysis, which is designed to examine whether a text message was erased from a cellular device’s memory chip. This method can work even if the messages were deleted from the memory itself, but was only saved as a file. There are several other kinds of ISeparatio techniques.
Extensive Data Contained: Many people wonder just how much data can be contained in a text message. Well, it all depends on how the program was written, and how many characters were actually contained within it. Generally, an average sized text message usually has around 40 characters. However, if the software contains special characters or uses the cellular format correctly, then even more data may be recovered. Sometimes, text messages contain symbols or words which can be used to decipher their meaning. If an investigator can decipher this kind of data, then he or she will have an upper hand when it comes to proving the suspect had a malicious intent to obtain cell phones’ data.
Recovery of Deleted Text Messages: Even though it’s not always possible to recover deleted text messages from cellular phones, this is still one of the most important things to do for cell phone forensics. In particular, an investigator can sometimes recover images from the phones themselves, which can often provide some very useful clues. The truth is, there are quite a few different programs available which can recover deleted text messages from phones. Unfortunately, not all of these programs are capable of being updated to include more recent versions of the operating systems. Therefore, if a person is going to try to recover deleted text messages from a cell phone, it’s really a good idea to take into account what the newest version of programs available can actually do.
Retrieving Call Logs From a Mobile Device: Although call logs are commonly recovered from a cell phone by forensics professionals, it’s still interesting to see what information might be found on a mobile device. This is because call logs usually contain a wealth of detail, such as who the line belongs to and whether the call was made or received by anyone at all. Call logs can also often contain IP addresses and the source and destination of any outgoing calls. These details can make a huge difference when it comes to tracing the location of where a cell phone was used. This is the main reason that the FBI and other law enforcement agencies such as the CIA have agents whose job it is to track cell phone activity.
There are also several online tools that can be used to recover this data. This is especially true with the software tool called “XoftSpy”. It can be downloaded from the website below:
