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!

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.

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.

Related image

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.

Where should you Install Security Cameras at your Business?

Your business is an important part of your life and in order for it to function properly you need to make sure the correct security measures are in place.

It’s not possible for you to go around monitoring your entire company grounds, but it is possible to use the power of technology to do so.

Many businesses have taken to installing security cameras to keep an eye on what is going on when no one is watching. Here’s why it is vital to install security cameras:

     1.       Safety and security in the office

     2.       Preventing theft, crimes and violence

     3.       Ensuring employees are performing their jobs properly

     4.       Settling disputes

     5.       Keeping an eye on unknown visitors

The most popular reasons why companies turn to using security cameras is crime prevention and investigation. Why? Because cameras record and save everything that goes on, meaning as a business owner you can go back and view an incident and find out what really happened. This footage can be used as evidence to sort out legal issues.

However, to get the maximum results from your camera you need to install them in the appropriate locations…

      -          Entrances / Exits
      -          Reception Area
      -          Office Area
      -          Store Rooms
      -          Customer Interaction Points
      -          Warehouses
      -          Loading Docks
      -          Any Secluded Locations (alleys, parking lots, dumpsters)

To have complete peace of mind you need to know that your business is protected and secure. Don’t be a victim, keep yourself and your business safe by installing security cameras!

The TCG Digital Forensics Division offers a range of services around analysis and the enhancement of CCTV footage, providing you with the footage and evidence that you need.

Our experts use a wide variety of forensic imaging technology to help to improve the quality and clarity of any images, allowing you to pick out certain important things such as vehicle registration numbers and facial features.

Russian Hacker Sentenced to 27 years Behind Bars!

Next time you think about learning how to hack illegally, think about this man! The 32 year old son of Russian parliament member, Valery Seleznev, was recently sentenced to spend 27 years behind bars for his cybercrimes.

Image result for hacker

The hacker’s crimes were: stealing millions of payment card details from businesses by infecting malware into their point-of-sale systems.

27 years is a long time, in fact, it is the longest ever given out in the US for hacking or computer crimes!

The son of Seleznev, Roman Seleznev, was sentenced last Friday in Washington after being found guilty of a range of crimes including; wire fraud, intentional damage to a protected computer, obtaining information from a protected computer, possession of unauthorized access devices and aggravated identity theft.

In the dark world of cybercrime Roman Seleznev was known for trading stolen payment card data. He would use a few aliases – Track2, 2pac or nCuX – and he succeeded in selling millions of private credit card details to criminals all over the web.

Authorities in the US say that for about four years Seleznev infected malware into more than 500 businesses, where he would then capture all their card data and transfer it to servers under his control.
When he was arrested a few years ago, the laptop that he owned had more than 1.7 million stolen credit card numbers on it!

To try and get mercy Seleznev sent a letter to the judge earlier this month. He explained how his rough childhood including his life of poverty and his parents’ divorce had affected him deeply. His mother’s death when he was just 17 sent his world spiralling out of control; he had to drop out of college and try to pay the bills.

Image result for credit card hacking

During this tough time is when he discovered the trading of credit card data and that he could use his computer skills to hack into businesses.

After Seleznev’s strict sentencing, he made a statement of a different tone, claiming he was a political prisoner that was kidnapped by the US government.

A hacker can target anyone - even you! It can happen to anyone, so if you feel your computer or private data has been hacked do not hesitate to contact our TCG Forensic Division. Our digital forensic experts will assist you in any way you need! Call 087 001 0511/2 or email

When Kari Baker, a 31 year old teacher, died of a sleeping pill overdose everyone thought she had taken her own life. Her body was found with a suicide letter and a bottle of sleeping pills close by, but her family had suspicions that it was her husband, Matt, that was responsible for her death.

Because of problems that occurred in the investigation of Kari’s death, Matt walked free. However new evidence emerged when Kari’s parents instigated a wrongful death lawsuit.

Apparently the story of Kari killing herself was completely wrong! It came to light that Matt had really killed his wife. He slipped her some sleeping pills, waited for her to fall asleep and then suffocated her with a pillow.

The real evidence though was the important data recovered from his laptop’s hard drive and the main computer server at the youth centre where he worked. Digital forensic specialists were able to pull up data and reveal that Matt had searched online for information about overdosing on sleeping pills and he even looked at pharmaceutical websites after she died.

A computer forensic expert who was involved in the case also discovered that Matt regularly looked at pornographic websites and sites where married people went to have affairs.

Matt Baker was sentenced to 65 years in prison for murdering his wife Kari.

Technology continues to play an important role in our everyday lives, because of this digital forensics has found a way for experts to convict criminals using digital evidence.
