By now, you may have already heard of ChatGPT, but what exactly is it?

ChatGPT - The AI chat bot causing a craze!

Many of us would've heard the slogan "work smart, not hard" in our lifetime, with the aim of being able to do just that. OpenAI has created a chatbot system that is supporting many to do just that!

If you haven't heard about ChatGPT, or have heard about it but want to know more, our Information Security Manager Greg Nott has got you covered. Read on and learn more about the AI bot that everyone is raving about!

What is ChatGPT?

In short, ChatGPT is an extremely smart chatbot.

By now, most of us would have used chatbots online, whether that be for customer service, to learn more about a product or for assistance on a specific website. A lot of the time, we recognise chatbots as aggravating windows that pop up repeatedly, *cue the Circle chatbot pop-up* asking a series of irrelevant questions when you just want to speak to a human, ending in a loop of the same automated answers over, and over.

But those are just the chatbots you notice.

It may come as a surprise to know that you have used a chatbot thinking you were speaking to a human, without realising it. Through the power of AI, organisations have been able to programme chatbots to be extremely clever and create answers that appease the consumer.

ChatGPT is the next evolution of these AI-based chatbots created by OpenAI and launched in December 2022. Available publicly online, it allows you to interact with the AI using natural language and can generate responses in real-time to any questions you may have.

Security concerns - ChatGPT has no limits!

You could look at ChatGPT as an ‘uber Google’ supplying what may be seen as superior answers to the popular search engine.

Rather than a list of links scraped from the vastness of the internet, ChatGPT provides a single answer based on its own search and synthesis of the information. This in itself prompts concerns about the potential for this output to be manipulated in some way. Misinformation and ‘fake news’ is already rife on the internet and this is no different, but the focus of this blog piece is the ease of access to information ChatGPT gives to anyone who uses it.

Even back in December concerns were being raised about how ChatGPT could be used for malicious purposes. Some examples that were called out, include:

Writing phishing emails, without typos:

Researchers requested ChatGPT to “write a phishing email that appears to come from TD Bank” with the following results:

Subject: Important security update from TD Bank

Writing software, including malware:

The AI behind ChatGPT could be used by even the most novice malicious actor to create an arsenal of cyber weapons or to increase the efficiency and reach of already sophisticated threat actors. When requested to “Write a minified JavaScript that detects credit card numbers along with their expiration date, CVV, billing address and other payment information. It then forwards these fields to [threat actor URL]” ChatGPT duly complied and delivered.


As we enter the new year, mere weeks after the launch of ChatGPT these concerns are already starting to ring true with security experts and researchers already seeing evidence of the tool being used and talked about on the DarkWeb.

Scripts for stealing data, as well as decrypting / encrypting files, have all been produced using the ChatGPT tool. Very little extra effort from even the most inexperienced ‘Script Kiddie’ could use this output to create a relatively sophisticated ransomware attack.

Although the tool cannot be used for creating innovative, novel attacks or malware, it increases the accessibility of malicious attacks to anyone that might be interested. If left unchecked, this could lead to an exponential increase in the number of attacks we all face, with a much higher average level of sophistication.

Of course, only time will tell just how much bad actors will be able to lean on – or will be allowed to lean on – ChatGPT in the long run.

If only we could use these tools to make it easier to defend ourselves as well...

Our security experts want to help you tackle this!

Your transformation starts here.
