What can be done about Identity Theft?

With millions of people affected by identity theft every year, this online crime is nothing new. But as the years go by we will see fraudsters going to extreme lengths in order to steal your private information.

One method that will be widespread is using captured online videos. But how will this work? Online criminals will post fake job vacancies and request a short video and/or a meeting over Skype. 
Regardless of how they will obtain the video, they will have a recording of you talking about yourself, this will aide them when they open an online bank account!

Why is this happening? As banks try to compete to get the attention of the younger generation they will focus more on how easy the banking application is to use instead of focusing on the long term benefits of signing up.

To get the most out of your security camera system, your cameras should be placed where they can capture the best possible footage…

Place at eye level – A camera that is close to a ceiling will cover a wider area, but that isn’t the best angle when it comes to capturing footage of a suspects face.

Don’t aim towards lights – Lighting from a window or a lamp, etc. can create silhouettes, this in turn makes it difficult to recognize a possible suspect.

Avoid it being too far away – A camera that is placed too far away is not likely to capture a high quality image of a suspects face, making it hard to identify someone.

Use multiple cameras – The more angles you have covered by cameras, the better your odds are of capturing a suspects face or any other evidence.

We hope you never need video evidence to investigate, but the tips above will improve your chances in the even that you do!

Your regular IT Guy just won't make the grade when it comes to a forensic investigation - and this is why...

We often have clients and potential clients advise us "We'll get our IT guy to look, he's excellent"

Now we're not questioning your IT guys skill or experience in computing in any way whatsoever and we're quite sure he's very capable. That being said, when matters take a legal turn and a forensic approach is needed one has to look at the requirements for the assessment itself.

Firstly, will your IT guy stand up in court? Will be stand under cross examination and be admitted as an expert in his field? Will his deeper understanding of operating systems and data analysis pass scrutiny?

Before you can even consider the legal aspects, you need to appreciate that in forensic terms whatever is done must be replicable in court, properly presented as an impartial finding and of course happen within a secure chain of custody - anything less could put the outcome at risk in a court of law.

Digital Forensics is a highly specialized field which requires training in investigative skills and criminal/ civil law. This is before even going down the road of the technical proficiency and qualifications required to trade in the industry. Beyond this, one requires a veritable arsenal of specialized tools and equipment - even the most basic of lab facilities can cost R500k to equip.

Even the most seasoned IT professionals will not have access to the specialized tool set required and a free Linux tool or two just isn't sufficient. Cybercrimes and Forensic Investigation require the use of tools that will be acceptable to a court and do not alter the data in any manner whatsoever during the process (write blocking), this is of course done with a detailed understanding of the legal processes required to offer up evidence in court.

When engaging a Digital Forensics specialist, you're not just getting a set of hands - you're hiring an investigative professional with specialist skills armed with the latest technologies to ensure that evidence is acquired in a sound manner and correctly presented to court.

When you need a Forensic Investigator, ensure that you're dealing with a suitably qualified professional who has the academic qualifications as well as the track record to appear in court to quantify the evidence acquired and advise you accordingly during the investigation.

Protecting yourself from Package Tracking Scams

Scammers are creative, they seem to be coming up with new scams every week – and people always seem to fall for them!

Related image

In the past few years, large amounts of package tracking scams have popped up. The scam will include an email trying to convince you to click a link or give out your private information. Most of the time the email will advise you that there is a shipping problem and you need to take some steps to clear the package that you didn’t even know you were receiving.

Even though most of these scams are easy to spot because of their awful English spelling and grammar, some are so well done that they can be difficult to spot. Keep an eye out for these signs so you do not fall victim to a tracking scam…

- Odd URLs
- Requests to input your private information
- Requests to click a link
- Email messages starting with “Dear Customer”, etc.

NEVER give out any information about yourself and never click on links in an email, no matter how real it may look!

The bottom line is if you are not expecting a package and someone invites you to click a link to track a shipment of a brand new iPhone you never ordered – delete the message and move on!

At TCG Digital Forensics, we do all forms of digital forensics services such as cyber forensics, hacking recovery, cellular phone analysis and digital track and tracing! Give us a call on 021 110 0422 or email to discuss your specific requirements.

Important Online Safety Tips for Children & Adults!

These days we use the internet for just about everything – shopping, chatting with friends, working and just browsing for more information. However, because the internet is so involved with our everyday lives there will be some dangers we will face.

With the right information, knowledge and tips you can protect yourself as well as your loved ones – here are some of the more important online safety tips…

Online Scams

Most scams these days are so complex that they are hard to spot as scams in the first place.

A friend / family member emails you that they need help and they need you to send them some money – always make sure to contact them first and make sure it was actually them that sent you the email.

When you purchase something online – always double check that the website is actually real and not a scam to try and steal your banking details.

Online Bullies

It may be online, but bullying is still bullying and it is just as hurtful as real life. Young children and teens are usually the victims, but adults can also be targets. Use these steps if you feel you’re being bullied online…

1. Always remove yourself from the situation. Simply block the person doing the bullying or step away from your computer.
2. NEVER respond to a bully! This will make the situation worse, so it is best to just ignore them.
3. Keep track of all the emails, messages, etc. that the bully has sent you in case the matter gets serious.
4. Do not be afraid to report a bully if you think they are getting out of hand!

Online Predators

Always be suspicious of people who are pretending to be friendly to gain someone’s trust, especially with young children and teenagers.

> It is best to keep track of what your child does online as well as who they are chatting with.
> Keep all online profiles secure and generic to avoid stalkers.
> Signs such as depression can indicate that your child is a victim – always be on the lookout!

Should you fear that you are not secure online, contact TCG Digital Forensics in Cape Town or Centurion, we will assist you in any way possible! Call 021 110 0422 or email

All you need to know about Digital Forensics and Information Security

Before we get into the differences between digital forensics and information security, let’s stop and take a look at how they are alike.

Related image

Both digital forensics and information security are aimed at protecting your digital data, goods and valuables as well as digital resources. People who are involved in digital forensics or information security can work in a range of industries, including private businesses and organisations. Why can people in the digital forensics and information security work in so many different industries?  Because, companies know that as the world becomes more digitally dependant so does the need to keep their technology and systems properly secured. Digital forensics and information security specialists are becoming more and more popular as the demand for their skillset grows.

But, just because digital forensics and information security are both focused on digital goods and resources doesn’t mean the two are both closely associated with each other doesn’t mean they are the same.

It is best to think of digital forensics and information security as two different sides of the same thing, so the services and work that is done is very much the same, but it does have differences.

So what is the difference between digital forensics and information security? To put it into simple terms that everyone can understand, information security is about preventing and protecting against online and digital threats. On the other hand digital forensics is about the response that comes after.

Let’s look at it like this – information security is the team that executes and supports the information security system with the aim being to protect individuals and businesses against cyber threats. If information security fails to protect the users and the systems are broken, then this is where the digital forensics experts come into the picture – they will put their skills to use by singling out the threat, understanding it and trying to recover all the data that was lost and/or stolen.

At TCG Digital Forensics, we offer all our clients clean, professional and affordable digital forensics services as well as information security – all supplied by our team of skilled digital forensics experts.

What do you know about SMS & Mobile Phone Phishing?

Because there has been a rise of mobile phone messaging services such as WhatsApp and Facebook messenger, cybercriminals now have a new way to attack users!

SMS phishing or SMiShing works in the same way as email phishing – the victim is sent a fake offer or warning that appears to be from a legitimate company or organization. The message usually contains a malicious link that the victim is persuaded into clicking.

A SMiShing message is often short and to the point with the aim of shocking or scaring a user into clicking the link without thinking twice. A common method is when cybercriminals pretend to be from a bank, warning the victim that their account has been closed, disabled or compromised.

Because the fraudulent message is received via SMS or private message, it can be difficult to realise the message is fake. Why? Because these messages do not contain warning signs of a scam such as the senders email address. Without knowing the SMS is fraudulent, the victim will click on the link willingly and hand over their private information and/or passwords to the cyber attackers.

Here are some helpful tips on preventing SMiShing:

1. Do not click on unknown SMSs or private messages hat contain links!
2. Never reply or give out your personal information if you receive an SMS asking you to
3. If the SMS asks for a quick/urgent reply this is a sign of SMiShing
4. An SMS states “Congratulations, you have won”, etc. this is another sign of SMiShing
5. Should you receive an SMS from your bank, always call your banks customer service line first to double check that it is legitimate

Trust your instincts – if the SMS doesn’t seem right, do not click on it!

TCG Forensics offers a range of cellular and digital forensics services. Should you need the assistance of an expert forensic investigator please do not hesitate to give us a call on 021 110 0422 or email

How to protect yourself against SMS Phishing Attacks (SMiShing)

Everyday scammers are coming up with new ways to target people and trick them into parting with their money. Nothing digital is safe anymore – social media networks, emails and now even SMSs.

SMS phishing, otherwise known as SMiShing, are phishing scams that are sent out on SMSs!
Here are some helpful tips on how to spot a SMiShing scam SMS…

Always double check SMSs from your bank. If your bank does send you SMSs, then be sure to find out what number they use so if you receive an SMS you can compare it and find out if it’s legitimate. If you do now know the number, call your bank’s customer service number just to be sure.

Be wary of suspicious-looking numbers & links. Scammers are likely to mask their identities so they will use a variety and different phone numbers as well as unusual links in SMS scams – if you receive any SMSs from strange numbers that you do not recognise always double check with whoever sent it and NEVER link on a link you do not recognise.

Report threats. Should you ever receive regular SMS scams, any threatening or potentially dangerous SMSs always report it to the local authorities, cybercrime centre/website or get in touch with a professional digital or mobile forensics expert from in South Africa – call 021 110 0422 or email

Always stay vigilant and be aware of the common techniques that SMS scammers use when they’re SMiShing – this will go a long way when it comes to keeping yourself and your money safe!
