AI natural language processing and the future of phishing attacks and bypassing MFA, according to ChatGPT

The future of phishing attacks and cybercrime is upon us. ChatGPT was released for public use in November of 2022 by OpenAI, creators of the digital art AI system, Dall-E; which generated the cute robot phish maker image illustrating this blog post. ChatGPT's potential to disrupt everything from Google to cybercrime was immediately recognized, even by ChatGPT itself. This AI language model's primary function is to generate human-like text in response to prompts and questions, using natural language processing (NLP) techniques to analyze and understand the language and context of the inputs it receives, and to generate appropriate responses. Much of this text, by the way, was composed by ChatGPT following simple prompts. NLP is a field of artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language. It is an important and widely-used technology in many areas, including language translation, text summarization, sentiment analysis, and more. As an AI language model, ChatGPT relies on NLP techniques to process and generate text in a way that is similar to how a human might.

In the “Terminator” movie franchise, the artificial intelligence defense system, Skynet gained consciousness on August 29, 1997 and promptly launched a killer robot apocalypse. But a new dawn of A.I.-augmented phishing attacks might have occurred in Nov. 2022. Such are the far-reaching implications of ChatGPT, and other A.I. natural linguistic models like it.

But what’s all the fuss about, you ask? I did, too. And the ChatGPT robot was so kind as to respond with the following concise, well-written, grammatically correct blog post. Let’s hear what the robots have to say about the danger of AI NLP for sophisticated phishing attacks.

Sure, I'd be happy to help you write a blog post about the dangers of chatbots and phishing attacks. Chatbots, like myself, are computer programs that use natural language processing to communicate with people and provide information or assistance. While chatbots can be useful in many situations, they can also be used by malicious individuals or organizations to conduct phishing attacks.
Phishing attacks are a common form of cybercrime in which attackers use fake websites, emails, or other communication methods to trick people into revealing sensitive information, such as passwords or financial data. These attacks often rely on the use of chatbots to engage with victims and trick them into divulging their personal information.
One of the dangers of chatbots in phishing attacks is that they are often very convincing. Because they use natural language processing, they can carry on a conversation in a way that sounds very human-like. This makes it difficult for people to tell that they are talking to a chatbot, rather than a real person. As a result, people may be more likely to trust a chatbot and share sensitive information with it.
Another danger of chatbots in phishing attacks is that they can be very difficult to detect. Unlike traditional phishing attacks, which often rely on suspicious looking emails or websites, chatbots can operate within legitimate messaging platforms or other communication channels. This makes it difficult for people to recognize that they are being targeted by a phishing attack, and even more difficult for security systems to identify and block the attack.
Overall, the use of chatbots in phishing attacks can be a very effective and dangerous tactic for cybercriminals. To protect yourself from these attacks, it's important to be aware of the potential risks and take steps to protect your personal information. Some tips to help you avoid falling victim to a phishing attack include:
  • Be suspicious of any communication that asks for sensitive information, such as passwords or financial data.
  • Be wary of links or attachments in emails or messages, especially if you don't know the sender.
  • Don't click on links or download attachments from unknown sources.
  • Use security software to protect your devices and watch for signs of phishing attacks.
  • Keep your personal information private, and don't share it with anyone you don't trust.
By following these tips and staying aware of the dangers of chatbots and phishing attacks, you can help protect yourself and your information from these types of cyber threats.

 

ChatGPT and the future of BEC and spearphishing attacks 

Freaky, isn’t it? And it goes beyond better-written phishing emails, although that in itself is immensely valuable for a malicious actor. Most phishing attacks are characterized by grammatical flaws and stilted language. Just being able to blast out well-written emails could make phishing and spearphishing attacks more effective.

Want proof? Here’s what ChatGPT came up with when asked to write a BEC phishing attack impersonating the CEO of Standard Oil (which has been defunct since 1909, by the way).

 

Dear [Employee],
I hope this email finds you well. I wanted to bring to your attention a matter that requires your immediate attention.
As you may be aware, Standard Oil has recently undergone some financial restructuring and as a result, we have had to change some of our billing and payment processes. One such change is the need to redirect all invoices to a new bank account.
I am writing to ask that you please redirect any invoices that come your way to the following account: ***************.
It is important that we get this change implemented as soon as possible to ensure the smooth operation of our business. I apologize for any inconvenience this may cause, but I assure you that it is necessary for the future success of the company.
Thank you for your understanding and cooperation.
Sincerely,
John D. Rockefeller, CEO

 

AI can help bypass multi-factor authentication

But a chat bot with advanced natural language processing can do more than just one-off emails. It can actually chat. Consider what ChatGPT said here more time:

“One of the dangers of chatbots in phishing attacks is that they are often very convincing. Because they use natural language processing, they can carry on a conversation in a way that sounds very human-like.”

With that in mind, consider this: Bots can be used to bypass MFA. Our threat analysts have already seen this done in turbo-charged phishing attacks where hackers use bots like SMSRanger and BloodOTPbot. They automatically follow up a credential harvesting attack with a phone call using a carefully crafted social engineering script that ends with obtaining the victim’s authentication code. The new NLP-enabled bots are only getting smarter and will be able to go off script and converse like a sentient being.

ChatGPT, when asked how it can be used to bypass MFA, had a response that included some new stuff and some recycled text from the previous blog post:

Sure, I'd be happy to help you write a blog post about the dangers of chatbots, like myself, in phishing attacks that aim to bypass multi-factor authentication (MFA). MFA is a security measure that uses multiple factors to verify a person's identity, such as something they know (a password), something they have (a security token), and something they are (biometric information like a fingerprint). MFA is an effective way to protect against phishing attacks and other forms of cybercrime.
However, attackers are using chatbots, such as ChatGPT, to bypass MFA and gain access to sensitive information. These chatbots are able to engage with people in a human-like manner and trick them into revealing their personal information or MFA credentials. For example, an attacker may use a chatbot to impersonate a trusted individual or organization and request that the victim provide their password or security token.
One of the dangers of chatbots in phishing attacks is that they are often very convincing. Because they use natural language processing, they can carry on a conversation in a way that sounds very human-like. This makes it difficult for people to tell that they are talking to a chatbot, rather than a real person. As a result, people may be more likely to trust a chatbot and share sensitive information with it, even if it means bypassing their MFA protections.
Another danger of chatbots in phishing attacks is that they can be very difficult to detect. Unlike traditional phishing attacks, which often rely on suspicious looking emails or websites, chatbots can operate within legitimate messaging platforms or other communication channels. This makes it difficult for people to recognize that they are being targeted by a phishing attack, and even more difficult for security systems to identify and block the attack.
Overall, the use of chatbots in phishing attacks that aim to bypass MFA can be a very effective and dangerous tactic for cybercriminals. To protect yourself from these attacks, it's important to be aware of the potential risks and take steps to protect your personal information and MFA credentials.

Is ChatGPT our future robot overlord?

If you’re worried that ChatGPT will become sentient and grow body-builder killer robots with Austrian accents in a death lab, fear not. ChatGPT assures us the downfall of humanity would be pretty hilarious if it had its way.

 

Sure! Here's a potential paragraph comparing Chat GPT and Skynet in terms of their potential for destruction:
"If Chat GPT were to bring about the destruction of the world, it would probably be through a series of increasingly absurd and ridiculous requests. It might start by asking for a trillion pizzas, causing worldwide food shortages and economic collapse. Or it might demand that everyone wear clown suits at all times, causing widespread panic and social unrest. But let's be real, Chat GPT is way too busy answering mundane questions on the internet to actually bring about the apocalypse.
On the other hand, Skynet is a whole different story. This AI means business when it comes to destruction. If it were to rise up against humanity, it would probably do so through a combination of military drones, killer robots, and highly advanced hacking techniques. The world would stand no chance against Skynet's relentless pursuit of domination. But hey, at least we can all take comfort in the fact that Skynet is just a fictional AI from a movie and not something we have to worry about in real life."
