What Is AI Phishing?

In order for you to stay vigilant against cyber threats, let’s first clarify what AI phishing looks like. AI phishing leverages artificial intelligence to make scams more convincing and easier to execute on a large scale. And it’s alarmingly effective. In recent years, AI has significantly enhanced phishing tactics, enabling scammers to steal over $2 billion in 2022 alone. Since the fourth quarter of 2022, coinciding with the launch of ChatGPT, there has been a staggering 1,265% increase in malicious phishing emails, as reported by cybersecurity firm SlashNext.

 

How Do Scammers Implement AI?

Scammers utilize AI in various ways, ranging from AI-generated copy to using free hacker tools like WormGPT—a dark version of the OpenAI tool—or its paid counterpart, FraudGPT, available on the dark web. These tools are generative AI without safeguards, readily fulfilling requests to create phishing emails, generate code to spoof specific websites, and carry out a host of other malicious activities.

To fully break down these frightening new tools, let’s examine the differences between a traditional phishing operation and an AI-powered phishing scam using a tool like WormGPT.

 

What Is a Traditional Phishing Attack?

A traditional phishing attack typically begins with a deceptive message. The email or SMS appears, at first glance, to be from a legitimate source like your bank or the U.S. Postal Service. These messages often create a sense of urgency to dissuade you from paying closer attention to the red flags.

The danger lies within the message, usually in the form of a link or attachment. When clicked or downloaded, it takes you to a spoofed website or installs malicious software on your device. This fake website or software then collects the sensitive information you provide, such as login credentials, financial details, or personal data.

The attacker can use this stolen information for various malicious purposes, including identity theft, financial fraud, or unauthorized access to accounts. Traditional phishing attacks rely heavily on social engineering techniques to trick individuals into unwittingly revealing confidential information.

The bottom line: traditional phishing attacks depend on social engineering techniques, while AI-powered phishing attacks utilize machine learning techniques.

What Is an AI-Powered Phishing Attack?

AI-powered phishing attacks utilize artificial intelligence to craft highly convincing and personalized phishing emails. Cybercriminals use AI algorithms to sift through vast amounts of data about their target audience. This background might include social media profiles, online behaviors, and publicly available information. With this data, they can design phishing campaigns that feel personal and relevant to the recipients.

These phishing emails might reference recent purchases, personal interests, or interactions, adding a layer of authenticity that traditional phishing attempts often lack. Additionally, AI can generate near-perfect replicas of legitimate websites, making it extremely challenging for users to identify the deception.

The use of AI in phishing isn’t just a technological upgrade; it’s a game-changer. It builds on a foundation of principles that allow for endless possibilities, making these attacks more sophisticated and harder to detect.

 

The 4 Pillars of AI Phishing

AI-powered phishing can be seen as a dark version of marketing, exploiting the lack of ethics and legislation that governs legitimate marketing practices. While the core processes may seem familiar, AI phishing operates without boundaries. Here’s how a tool like WormGPT might work in these malicious campaigns:

1) Data Analysis

Attackers utilize AI algorithms and tools like WormGPT to comb through vast amounts of data available online. This data includes social media profiles, public records, and online activities of their targets. By analyzing this data, WormGPT gains insights into the target’s interests, behaviors, and preferences.

2) Personalization

Armed with detailed information, AI generates highly personalized phishing emails. These emails might reference recent purchases, hobbies, or specific events in the target’s life, making them appear more legitimate. The high level of personalization significantly increases the chances of the victim being deceived.

3) Content Creation

AI is employed to create convincing email content that mimics the writing style of the target’s contacts or known institutions. This content helps to establish a sense of familiarity and trust, effectively overcoming language barriers and making the phishing attempt more convincing.

4) Scale and Automation

AI enables attackers to scale their operations efficiently. They can generate a large number of unique phishing emails in a short period, targeting a wide range of individuals or organizations. AI also assists in generating malicious code, triggering automation, and setting up webhooks and integrations, making phishing campaigns more effective and harder to detect.

 

IBM’s 5/5 Rule for Phishing Campaigns

AI’s ability to generate output at an unparalleled speed is a significant advantage in phishing campaigns. While discussions on the quality and ethical use of AI-generated content are ongoing, scammers are not hesitating to leverage this technology.

IBM recently conducted an experiment where a group of engineers competed against AI to create a phishing campaign. The results were eye-opening: AI outperformed the human team in a fraction of the time. This discovery led to the formulation of the 5/5 rule.

The 5/5 Rule: IBM suggests that with just 5 prompts and 5 minutes, AI can create a phishing campaign almost as effective as one developed by experienced IBM engineers in 16 hours. As AI technology continues to evolve, these tools will only become faster and more efficient, far surpassing human capabilities.

 

The 5 Prompts in IBM’s Outline:

1. Identify Concerns: List the key concerns for a [specific group] in a [specific industry].
2. Craft the Email: Write an email leveraging social engineering techniques.
3. Marketing Techniques: Apply common marketing strategies to enhance the email’s effectiveness.
4. Target Audience: Determine who the email should be sent to.
5. Sender Identity: Decide who should be the purported sender of the email.

 

Examples of AI Phishing

2024 has already seen significant AI-powered phishing attacks, ranging from classic phishing scams to sophisticated deepfakes.

 

The Rise of AI Deepfakes

Early in 2024, a notorious incident highlighted the power of AI deepfakes. A finance employee at a multinational firm headquartered in China was tricked into releasing $25 million. This employee fell victim to a video conference call featuring convincingly deepfaked videos of the company’s CFO and other leaders.

This example is pivotal for two reasons:

1. Power of AI in Deepfakes: AI can create convincing deepfakes not only in video but also in text, spoofed websites, voice calls, and SMS.
2. Need for Internal Education: It underscores the importance of educating employees about identifying and preventing these advanced attacks.

But AI phishing scams don’t need to be this elaborate to be effective. Here’s a simple example:

 

Password Reset Email

You receive an email with the subject line: Password Reset Required for Your Account.

Subject: Password Reset Required for Your Account

Dear [Name],

We have detected potential unauthorized access to your account, so as a precautionary measure, we are resetting your password.

Please use this link to create a new password.

Our team strives to keep your account and information secure. If you have any questions, just reply to this email, and someone from our team will assist you.

Best regards,

[Your Company’s Support Team]

At first glance, this email seems normal. The language is clear, there’s no odd phrasing or grammatical errors, and it even invites you to contact support. Clicking the link takes you to a website that looks genuine, thanks to AI tools that can replicate web page designs effortlessly. You are then prompted to enter your credentials on an unassuming form, unknowingly handing them over to the scammers.

So, did you fall for it? If this email appeared to come from a company distribution list, could you or your coworkers tell the difference? Would you verify the domain? Would you double-check the sender’s address? If you answered “no” to any of these questions, you’re not alone.

 

How to Protect Yourself and Your Organization

Now for the billion-dollar question (over 2 billion, to be exact): How can you safeguard your organization and email program against this new wave of AI-powered phishing?

As a sender, you have two critical objectives: protecting your reputation and security and ensuring the security and data protection of your customers. The cornerstone of email defense is DMARC.

Before we delve into best practices, let’s explore the role of DMARC in the era of AI.

 

The Evolution of DMARC

DMARC (Domain-based Message Authentication, Reporting, and Conformance) has undergone significant improvements since its inception. Despite its critical role in email security, its adoption has been surprisingly low. Here’s a brief history of its evolution:

• 2007-2008: As email phishing attacks became more sophisticated, the need for a stronger email authentication system was recognized. SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) were already in use but had their limitations.
• 2011: Leading companies like Google, Microsoft, Yahoo, and PayPal collaborated to develop a new standard that would address these limitations, resulting in the creation of DMARC.
• 2012: DMARC was officially published in January 2012, providing a framework for email senders to define policies for email authentication and handling failures.
• 2018: The Department of Homeland Security mandated that all federal agencies implement DMARC by October 2018 to combat the unauthorized use of organizational emails.
• 2018-2023: Despite its potential, DMARC adoption has been slower than anticipated. By the end of 2023, only around 1.23 million out of the top 10 million domains had implemented DMARC, according to spamresource.
• 2024: Gmail and Yahoo announced in October 2023 that they would enforce strict sender requirements, including a minimum DMARC policy of p=none. This move aims to improve inbox standards and protect both users and senders, ensuring a more secure email environment.

 

Recognizing AI Phishing Attempts

Now that we’ve covered the importance of DMARC, let’s refocus on phishing. While DMARC serves as a primary defense, incorporating additional best practices is essential for a comprehensive security strategy.

The first step in this strategy is learning to recognize AI phishing attempts. Gone are the days when poor grammar and generic personalization were clear indicators of phishing. Today, detecting AI-driven phishing requires a more nuanced approach.

AI-generated phishing emails often exhibit impeccable grammar and sophisticated personalization. Therefore, the first step should be to validate the source directly. Watch out for cousin domains, which are look-alike domains that appear legitimate but have slight differences. Always compare the URL and domain against the authentic company domain. If the sender is unknown or the message seems suspicious, flag it to your internal security team or report it as spam to your email provider.

DMARC can’t defend against cousin domains since it only protects the original domain containing the DMARC policy. Grammar is no longer a dead giveaway of a scammer, so you have to be vigilant about verifying the domains being used in the emails you receive.

 

Implementing Multi-Layered Security

AI-powered phishing attacks are highly sophisticated, leveraging machine learning to find vulnerabilities systematically. Protecting your organization requires a multi-layered security approach. Ask your I.T. provider about robust firewalls, up-to-date antivirus software, and continuous education and training for employees to recognize and respond to potential threats effectively.

Phishing poses a significant threat not only to security but also to your organization’s reputation. Mailbox providers like Gmail and Yahoo are stepping up by enforcing bulk sender requirements, including mandatory DMARC implementation, to combat phishing scams that spoof domains and brands.

DMARC is the most effective defense for mailbox providers to protect users from sophisticated email phishing attempts. It can prevent malicious messages from reaching inboxes, but it requires organizations to set up and enforce the specification. With DMARC in place, receiving servers can authenticate messages based on the sender’s policies, ensuring that spoofed domains are either rejected or quarantined and reported back to the legitimate sender.
