The most important skills you need for a career in Digital Forensics

Tech meets criminal justice in the field of digital forensics--a branch of forensic science dealing with recovering and analyzing information from data storage devices (including computers, phones, networks, and more). Digital forensics examiners help track down hackers, recover stolen data, follow computer attacks back to their source, and aid in other types of investigations involving computers.

Want to know what it takes to become a digital forensics examiner? Here are some key skills needed for the career…

Analytical talent: It stands to reason that anyone in an investigative role needs to have the analytical skills required to piece together information and solve the case. Cyber security expert, Ondrej Krehel says: “High speed of analytical thinking, and precise observation skills, which are often gained and tested at high tech military and intelligence cyber units are also important skills to have." The ability to find patterns and make correlations is crucial in the investigation process!

Computer science/tech skills: Since digital forensics is such a technical field, it helps to come from a background studying or working with computer science. An important quality of any great digital forensics investigator is a deep understanding of how technology really works. If you have experience with computer systems, programming, or other related fields, this will help you transition into digital forensics since you will already have a general knowledge of how technology and networks work, how digital systems interact with each other, and what is possible from a compromise perspective.

Understanding of cybersecurity: The field of digital forensics is all about solving cybercrimes--and who has a better knowledge of those than cybersecurity professionals? It's impossible to guard against data breaches without knowing the techniques being used to target systems, and this same knowledge that helps to prevent crimes also is useful in solving them. Many of the most talented forensics examiners will have had experience working on a cybersecurity team.

Organisation: You can have a messy desk and be a great digital forensics examiner--but mental organisation is a must, as is organised record-keeping. Being extremely organised and thorough is a must! Documentation of your findings is necessary as it is often required to present them to others such as attorneys and judges.

Communication skills: In relation to the above point, digital forensics doesn't exist in a vacuum. The team you work with and people you work for need to know what's going on, meaning that you need to communicate it to them. According to Ondrej Krehel, "Having both strong writing and speaking skills is extremely important to effectively communicate your findings to other team members and your clients."

Desire to learn: Cybercrime is constantly evolving, so it's a must to keep your knowledge up-to-date and always seek out ways to be better at your job. To be a digital forensics examiner, you must have great pride to be one of the best in what you do. Self-critique skills for constant improvement of your work is a very desired trait!

As for higher education, degrees are helpful in breaking into the digital forensics field, but what really establishes someone's credentials is the product of their work and the ability to conduct digital forensics in very detail-oriented manner!
At TCG Digital Forensics, we do all forms of Digital Forensics such as Cyber Forensics (Penetration Testing / Hacking Recovery / Cyber Investigations), Cellular Phone Analysis, Hard Drive Analysis, Device Acquisitions and Due Diligence Investigations.

We can recover Computer Evidence quickly and easily!

People use their computers for almost everything; many of these things can be used against you. Hiding money, illegal activities, inappropriate emails and just about anything you can think of.

Often, if you are trying to hide something, you’ll make an effort to completely clean out your computer by deleting “everything” and reformatting. The problem is, when you contact IT support and you are told that all is lost, they probably have no idea what a digital forensic investigator can do!

The harsh truth is that the evidence is still there, waiting to be found, you just can’t see it. The only question is, do you want it recovered or not.

Many businesses that have a disgruntled employee, or feel that an employee is involved in unacceptable activities at work, may want to acquire some digital evidence, they can use a digital forensic investigator to recover all the evidence that they need.

At the TCG Digital Forensics Division, we are pleased to provide all the evidence that you need off of a computer, cellular device, laptop or tablet. The obvious advantage that we have is that we recover digital evidence that few others could and keep all affairs private!

Need something recovered? Don’t hesitate to give us a call on 079 691 0138 or email craig@tcgforensics.co.za

What is Mobile Phone Analysis?

As mobile devices become more and more dominant in our lives, the opportunity to store and circulate information is more possible than ever.

Image result for holding mobile phone

Mobile devices have many different features, like the ability to take photos and videos. When a multimedia file is taken, many devices automatically embed GPS location of the handset at that time. This then allows the location of the user at that exact moment to be established at a later date.

Multiple communication features, such as Bluetooth, WiFi 3G and 4G enable the transfer of information that can even cross international boundaries. Users can browse the internet, send and receive emails, post blogs and even removable media cards can be inserted into the device allowing information to be exchanged.

Depending on the client, the following information can be recovered from a mobile phone:
  • SMS
  • Email
  • Call history
  • Photos
  • Videos
  • WhatsApp history
  • Passwords

Mobile devices are similar to computers, but with far more powerful capabilities. The value of the evidence found on a smartphone or any other mobile device must never be overlooked! The TCG Forensic Division has the cellular and digital expertise to extract and uncover the evidence you need.

- Scaling/Pixel Interpolation: Re-size, or scale an image or video to a larger resolution to further identify suspects.

- Sharpening: Enhances the edge contrast of an image or video.

- Stabilization: This is most common today with smart phone video evidence. It reduces the amount of movement from the user that created the video evidence.

- Frame Averaging: Increase the quality of the image by combining data from surrounding frames as well as a better signal to noise ratio in your images or videos.

- Speed Reduction: Decrease the original playback of video evidence to view the events as they occurred in more detail.

What being a Digital Forensic Expert is all about

As technology advances, those in the criminal justice and criminology fields have to learn to change with it. More people conduct business online, and more occupations require at least some use of a computer or cellular phone.

To fight crimes involving computers and mobile phones, new career opportunities for digital forensic experts have started to become more popular.

What do digital forensic experts do? Well, as the name implies, they reconstruct and analyze digital information to aid in investigations and solve computer-related crimes. They can look into incidents of hacking, recover chat history and even recover lost or stolen data.

Some of the services of a digital forensic expert often include:

- Recovering data from damaged or erased hard drives

- Gathering and maintaining evidence

- Working with cellular devices, computers and other electronic equipment

-  Digital image enhancement

- Recovering SMS or chat history

Private companies and government organisations may employ digital forensic investigators full time, or they may contract for their services. Investigators will likely be involved in looking for violations of company policies regarding computer use as much as they will be involved in crime solving.

In addition to computer skills and related education and certifications, digital forensic investigators and digital forensic experts must also possess strong analytical and investigative skills. They need to be able to read and interpret data and to formulate conclusions, and they must be able to present their findings and conclusions in a format that can be easily understood.

A digital forensic expert’s job is both stimulating and rewarding. It allows you to put your unique skills and knowledge to work in a field that is truly helpful to others.
