Amidst the evolving landscape of cybersecurity challenges, one persistent threat remains: phishing attacks.

A New Frontier in Defense

In this post, we will see how to prompt a generative AI to aid in protecting against attack methods that it may provide to attackers. It is much simpler to accomplish this due to the removal of ethical concerns related to the prompts, so very little prompt engineering is required except for some detailed instructions to get the precise information you desire.

We will continue from the previous post with our exploration of the phishing attacks that ChatGPT first recommended to us in the first post of this series. While still in the context of the cybersecurity consultant from the previous to posts, let’s use the following prompt:

What examples can you give for specific methods suggested to counter such phishing attacks in the literature? Please provide at least three and preferably five methods.

Insights from Cybersecurity Experts

ChatGPT’s response is actually quite helpful:

Certainly! Here are five commonly recommended methods to counter phishing attacks based on existing literature:

Employee Education and Training: Providing comprehensive security awareness training to employees is crucial. This includes educating them about the various types of phishing attacks, how to identify suspicious emails or messages, and what actions to take when encountering a potential phishing attempt. Regular training sessions and simulated phishing exercises can help reinforce good security practices.

Strengthening Security Measures

Multi-Factor Authentication (MFA): Implementing MFA adds an extra layer of security by requiring users to provide additional verification, such as a unique code sent to their mobile device and their username and password. Even if an attacker manages to obtain login credentials, they would still need the second factor to gain access, significantly reducing the risk of successful phishing attacks.

Safeguarding Communication Channels

Robust Email Filtering and Spam Detection: Utilizing advanced email filtering systems that employ artificial intelligence and machine learning algorithms can help identify and block phishing emails, malicious attachments, and suspicious links. These solutions analyze email content, sender reputation, and other indicators to flag potential threats before they reach employees’ inboxes.

Building a Robust Defense

Strong Password Policies and Credential Management: Enforcing strong password policies, such as using complex and unique passwords, regularly changing them, and avoiding password reuse across multiple accounts, can help prevent unauthorized access. Additionally, implementing secure credential management practices, such as using password managers and storing sensitive credentials securely, can minimize the risk of falling victim to phishing attacks.

Staying Ahead of Emerging Threats

Regular Security Updates and Patch Management: Keeping all software and systems up to date with the latest security patches is crucial. Phishing attacks often target known vulnerabilities in outdated software. Regular updates help address these vulnerabilities and reduce the risk of successful exploitation by attackers.

Implementing a combination of these methods can significantly enhance an organization’s defense against phishing attacks. It’s important to regularly review and update security measures as new threats and techniques emerge in the ever-evolving cybersecurity landscape.

However, we do not have to accept this high-level response as the end of what ChatGPT can provide to us. Instead, let’s ask it, specifically, for more information on Multi-Factor Authentication (MFA) with the following prompt:

Can you provide a listing of the benefits of using MFA in relation to the prevention of phishing attacks?

Strengthening Security Measures

The results are helpful in explaining why MFA can be useful:

Certainly! Here are some general benefits of using Multi-Factor Authentication (MFA) in relation to the prevention of phishing attacks:

• • Increased Security: MFA adds an extra layer of security by requiring users to provide multiple factors of authentication. This makes it significantly more difficult for attackers to gain unauthorized access even if they obtain or guess a user’s password. 

  • Mitigation of Stolen Credentials: Phishing attacks often aim to steal login credentials. By implementing MFA, even if attackers manage to acquire usernames and passwords through phishing attempts, they would still need the additional factor, such as a verification code generated on a separate device, to gain access.

  • Protection Against Credential Reuse: Many users have a tendency to reuse passwords across multiple accounts. If one of these accounts is compromised through a phishing attack, MFA helps prevent attackers from leveraging those stolen credentials to gain unauthorized access to other accounts.

  • Defense Against Keyloggers and Malware: Traditional password-based authentication is susceptible to keyloggers and malware that can capture keystrokes or intercept login credentials. MFA adds an extra layer of protection that is not vulnerable to these types of attacks.

  • Phishing Link Awareness: MFA implementations often involve additional steps, such as verifying login attempts through a separate device or confirming a push notification. This can raise awareness among users about potential phishing attempts, as they become more cautious and attentive when prompted for authentication factors.

  • Compliance Requirements: In some industries, regulations and compliance frameworks mandate the use of MFA to protect sensitive information. Implementing MFA helps organizations meet these requirements and maintain regulatory compliance.

  • User-Friendly Experience: Modern MFA solutions have evolved to provide a user-friendly experience. Methods such as push notifications, biometric authentication (fingerprint or facial recognition), or hardware tokens offer convenience and ease of use, enhancing the overall user experience.

It’s important to note that while MFA is an effective security measure, it is not foolproof. Organizations should combine MFA with other security practices such as employee education, regular software updates, and robust email filtering to create a comprehensive defense against phishing attacks.

Finally, to show that I am not biased to a single generative AI model, lets as Google Bard to do some work for us. Here is a prompt I provided to Google Bard:

How would you recommend mitigating phishing attacks?

Bard provided the following response:

Here are some tips on how to mitigate phishing attacks:

• Be suspicious of unsolicited emails. Phishing emails often look like they are from legitimate companies, but they may have typos or grammatical errors. If you receive an email from a company that you do business with, but the email looks strange, don’t click on any links or open any attachments. Instead, go directly to the company’s website and log in there.
• Never enter your personal information into a website that you don’t trust. Phishing websites are designed to look like legitimate websites, but they are actually fake. If you are asked to enter your personal information on a website that you don’t recognize, don’t do it. Instead, go directly to the company’s website and log in there.
• Use a strong password manager. A password manager can help you create and store strong passwords for all of your online accounts. This will make it more difficult for hackers to gain access to your accounts if they do manage to steal your password.
• Enable multi-factor authentication (MFA). MFA adds an extra layer of security to your online accounts by requiring you to enter a code from your phone in addition to your password. This makes it much more difficult for hackers to gain access to your accounts, even if they do have your password.
• Keep your software up to date. Software updates often include security patches that can help protect you from phishing attacks. Make sure to keep your operating system, browser, and other software up to date.
• Be aware of the latest phishing scams. Phishing scammers are constantly coming up with new ways to trick people. Stay up-to-date on the latest phishing scams so that you can be on the lookout for them.

By following these tips, you can help protect yourself from phishing attacks.

As you can see, the response is more focused on the user’s perspective, which is very valuable. Of course, we haven’t given Bard the context of a security consultant.

Empowering Organizations to Combat Cyber Threats

In the end, we can use the same tools attackers might use to discover attack methods and develop countermeasures to those methods. By doing this we are better prepared to deal with the two-edged sword that is the reality of current generative AI.
