Mobile device forensics has become a major part of digital forensics. The use of mobile devices increasingly continues to gravitate between personal and professional use.
The main objective of mobile forensics is recovering digital evidence or data from a mobile device.
Following the appropriate methodology and guidelines is important for the examination of mobile devices to yield good results. This blog post will discuss the mobile forensics procedure.
The technological advancements of this century have become useful to us in all walks of life. The criminals of the 21st century have also unfortunately modified their criminal channels accordingly.
Data leaks, hacks, and breaches of sensitive information were not common more than a decade ago. However, cybercrime has become the most dangerous and discreet method of committing crimes today. To catch these technologically evolved criminals, digital forensics has also morphed accordingly. Cybersecurity has become an essential concern of most private and government sectors, and computer forensics engineers can prove helpful in this regard.
Serial killers are not like ordinary criminals that leave a trail of clues. What separates them from common murderers is their ability to get away with their crime multiple times. By the time they can even be suspected of the crime, they have already wreaked havoc on their targeted section of society or a particular community.
Audio and video forensics is considered a primary branch of forensic science in the digital world.
There are three basic principles of audio and video forensics – acquisition, analysis, and audio and video evaluation. This blog post will answer some of the frequently asked questions regarding audio and video forensics.
A calm evening, a romantic walk at the beach, and the shining moonlight; everything made it the perfect evening for a romantic third wedding anniversary. However, things turned deadly for husband Justin Barber and wife April when an unidentified assailant tried to rob them and then brutally gunned them down.
However, law enforcement experts quickly gathered compelling evidence and got their hands on the right man – Justin Barber.
Video evidence might seem to solve a crime. However, it can also lead to false accusations against someone who isn’t guilty.
The camera cannot lie; however, it can always be manipulated to alter the truth. This is where video forensic experts come in to authenticate and analyze video evidence in a legal case.
But, what makes a professional video forensics expert? This post explains how anyone can become a professional video forensics expert.
Every time there’s an investigation conducted for a criminal case, evidence is required to uncover the truth. Investigators are responsible for seeking and collecting data that can be used to get more details about the case and determine who the culprit is.
Evidence exists in various forms. Even if a particular form of evidence isn’t allowed to be used in courts, investigators can still use it to get more insight into the case. Let’s take a look at three of the most popular types of evidence used in investigations.
Digital forensics is a process often used in criminal investigations. It involves collecting digital evidence from various devices, tools, or infrastructures such as computers, mobile devices, emails, hard discs, and cloud storage systems.
Here are a few famous cases where digital forensics played a crucial role.
The Jessica Chambers case was cold since 2014. The good people of Courtland, Mississippi, found themselves wondering just who killed 19-year-old Jessica Chambers.
The death of a young girl is almost always traumatic—more so when the death is clearly a homicide.
In 2021, digital devices are quite common, with the most common ones being mobile phones, tablets, and computers. However, the emergence of IoT has made a plethora of electronic devices a source of digital evidence. For example, a digital camera can be used to view or store illegal images. The first responders in this case are digital forensic experts, who should identify and seize every electronic device to acquire evidence.
But how is this digital evidence gathered? Hear what our digital forensic engineer has to say!
Numerous sources can be used to collect digital evidence. Some of these sources are servers, cloud computers, USB memory sticks, CD-ROM, hard drives, digital cameras, mobile phones, computers, and the like. Some of the more non-obvious sources include web pages that should be preserved because they can change, as well as RFID tags. It’s important to ensure that extra care of data sources is taken so that nothing can modify or contaminate them as they’ll be used for digital forensic investigations.
Since the majority of digital information is volatile, it’s subject to change. Once it’s modified, identifying the changes or rolling back the data to its original state becomes a lot more difficult. Therefore, a cryptographic hash of digital evidence can be carried out and calculated. This hash must be recorded in a safe place to ensure there’s no contamination of digital evidence. This is crucial because it would allow computer forensic experts to establish whether someone fiddled with the original data evidence or not.
During the initial phases of the investigation, it’s a good practice to duplicate the original evidentiary media. Now, a combination of software imaging tools and standalone hard-drive duplicators can be used to fully close the entire hard drive. This can be done at the sector level, where a bit-stream copy of all parts of the hard drive’s user-accessible areas will be made. This means there won’t be any need to duplicate the file system. In order to prevent tampering, the original drive can be transferred to secure storage. While this imaging process is underway, a write-blocking or write-protection application or device can be used to make sure no information is made part of the evidentiary media during the computer forensic investigation.
It’s important to preserve the sources from which evidence is gathered so that the chain of custody remains intact. Otherwise, it won’t be possible to validate the results of the digital forensic investigation.
