AI Is Powering a New Kind 
of Phishing—Here Are 
10 Ways to Combat Them

There was a time when phishing emails were laughably easy to spot—full of spelling errors, strange formatting, and far-fetched stories about princes offering fortunes in exchange for bank details. But those days are over.  

So how can professionals of today, tell if a message in their inbox is real—especially when it looks like it’s from a colleague and reads flawlessly? The answer is becoming less clear. As generative AI grows more advanced, it’s changing phishing tactics. Today’s phishing emails are polished, persuasive, and often indistinguishable from legitimate communication.

Despite years of investments in email security, employee training, and fraud detection, phishing continues to be one of the most successful tools in a cybercriminal playbook. In 2024, the landscape shifted dramatically. Generative AI made phishing not only faster and more scalable but dangerously convincing. Now, industries across the board find themselves squarely in the crosshairs. How can these attacks be identified? What organizations can do to combat phishing attacks, and more, is what we will explore in this blog. Read along. 

How Phishing Evolved from Obvious to Ominous  

Let’s rewind.

Phishing used to be easy to spot. The classic red flags—misspelled words, strange fonts, generic greetings (“Dear Sir/Madam”)—made it clear that something was off. In most cases, these emails were mass-produced by attackers with limited resources and an even lesser grasp of language or tone.

But generative AI in phishing flipped the script. With AI tools, threat actors can now generate contextually accurate, tone-perfect messages in seconds.

Need to mimic a CEO’s writing style? Easy. Want to personalize an email using publicly available data from LinkedIn or a corporate website? Done. AI agents are able to out-phish even elite human red teams, at scale. In an ongoing AI Spear Phishing Agent experiment from 2023 to 2025, AI’s performance vs. humans has improved by a whopping 55%.

Although publicly available LLMs have rules in place to prevent malicious use, attackers can circumvent some of these restrictions with creative prompts. Motivated attackers also created their own malicious LLMs for use in cyberattacks. FraudGPT, WormGPT, and PoisonGPT are just a few examples available currently.  

What we are seeing now is a new breed of phishing email: clean, precise, targeted—and dangerous.

Phishing-as-a-Service: Now with AI on Tap

Thanks to the rise of Phishing-as-a-Service (PhaaS) operations, even low-level cybercriminals can get their hands on AI-generated phishing kits. These kits can automate everything from email generation and spoofed branding to form fields that capture credentials in real time.

This means that:

• Non-technical attackers can launch sophisticated campaigns.
• Volume increases dramatically. Hundreds of unique, believable phishing emails can be created and sent with the click of a button.
• Better Adaptability. If one email doesn’t get clicks, the attacker can quickly regenerate it using slightly different language or target a different department. 

Type of Phishing	Type of Content	Attack Benefit	Attack Example
Email Phishing	Email Message	Broad reach at a low cost allows attackers to target thousands of individuals simultaneously.	An attacker sends an email pretending to be from a bank, asking to verify their account details via a link that leads to a fake website.
Spear Phishing	Email Message	Highly targeted; increases the likelihood of success by using personalized information.	An email tailored to an individual, using their name and specific details, claiming to be from their employer.
Whaling	Email Message	Targets high-profile individuals within an organization, by gaining access to highly sensitive or valuable information.	A fake legal subpoena sent via email to a company's CEO, directing them to click on a link that installs malware.
Business Email Compromise (BEC)	Email Message	Direct financial gain by tricking employees into transferring money to attacker-controlled accounts.	An attacker impersonates a company executive and requests an urgent wire transfer to a supplier.
Vishing (Voice Phishing)	Voice Message	Exploits the trust people tend to have in phone communications, bypassing email spam filters.	A phone call from someone claiming to be from the victim's bank, asking to confirm account number, PIN etc. over the phone.
Smishing (SMS Phishing)	Text Message	Reaches victims through their personal phones, often catching them off-guard.	A text message claiming the recipient has won a prize and needs to click on a link to claim it.
Pharming	Website Content	Redirects users to fraudulent websites without their knowledge, capturing sensitive info.	Malware that changes the victim's DNS settings to redirect legitimate websites to phishing sites.
Pop-up Phishing	Website or Desktop Pop-up Content	Captures immediate attention with urgent or enticing messages.	A pop-up claiming the user's computer is infected, urging them to download fake antivirus software.
Watering Hole Phishing	Website Content	Targets specific groups by compromising websites they are known to visit.	Infecting a professional forum with malware that exploits vulnerabilities in visitors' browsers.
Angler Phishing	Social Media Content	Exploits social media interactions to steal personal information or spread malware.	A fake customer service account on Twitter offering to resolve issues, asking users to provide account details via direct messages.
Angler Phishing	Social Media Content	Exploits social media interactions to steal personal information or spread malware.	A fake customer service account on Twitter offering to resolve issues, asking users to provide account details via direct messages.
AI-Generated Video Phishing	Deepfake Video Message	Hyper-realistic videos increase trust and deception, making it easier to impersonate executives.	An employee receives a video call or message appearing to be from their CEO - mimicking the CEO's face and voice, urgently requesting funds transfer or sensitive document access.

The Human Element: Still the Weakest Link

Despite billions spent on cybersecurity, phishing still works. Why? Because it targets people, not systems. Users are clicking on phishing lures at a rate nearly three times higher than in 2023.  

And generative AI makes it personal.

Attackers can now tailor emails to specific individuals or departments using real data: recent company events, executive names, project references. They can fine-tune tone and timing, sending emails just before the end of a quarter or during holiday travel when teams are distracted.

Even trained employees get caught off guard. In fact, overconfidence in one’s ability to spot phishing can increase the risk. The more realistic the message, the easier it is to justify clicking “just this once.”

Here’s what’s changed 

4 Reasons Why AI-powered Phishing Works
Hyper-Personalization	Flawless Language	Context Awareness	Speed and Volume
AI used to scrape public data (like LinkedIn, press releases, and social media) to build highly tailored messages. An email might even reference the manager, current project, or even a recent Zoom meeting.	AI removes the usual red flags—poor grammar, odd phrasing, and clunky formatting. The result? Emails that read like they came from your internal communications team.	Generative AI can understand and respond to context. An attacker can craft a message that aligns with organizational jargon, industry language, or even the recipient’s role.	Want to target 1,000 employees across 100 companies with unique emails? AI can do that in minutes.

How Can Organizations Fight Back Against Phishing Attacks

So how do organizations protect themselves when phishing emails start sounding better than your internal memos? Here are some practical, actionable defenses:

1. Deploy Advanced Email Security Gateways

Emails remain the most common entry point for phishing campaigns—evading basic filters. Organizations are upgrading to Email Security Gateways (ESGs) that combine signature-based detection with behavioral analytics, threat intelligence, and machine learning.

These gateways don't just analyze the content of a message, but also sender reputation, domain behavior, metadata, and context. Suspicious messages can be automatically quarantined, and impersonation attempts flagged—reducing the burden on employees to distinguish real from fake.

In many organizations, these gateways are delivered as Email Security-as-a-Service platforms, offering global threat visibility and seamless integration with Microsoft 365, Google Workspace, and other enterprise mail systems.

2. Adopt AI-Powered Anti-Phishing Platforms

Basic spam filters are no match for AI-generated phishing emails. Organizations must deploy advanced anti-phishing platforms that use Natural Language Processing (NLP) or now LLMs, deep behavioral learning, and relationship mapping to detect sophisticated impersonation attempts.

These platforms understand what “normal” communication looks like inside the business. When a message deviates from an established tone, timing, or structure, it’s flagged—even if it passes through every traditional filter. Combined with real-time alerts and remediation capabilities, these platforms enable identification and containment of threats before they spread.

3. Strengthen Identity Security with Phishing-Resistant MFA

Most phishing attacks still aim to compromise credentials. To reduce risk, organizations should look beyond simple username/password combinations and deploy Multi-Factor Authentication (MFA) across all user accounts—especially those with privileged access.

Where possible, phishing-resistant methods such as FIDO2 tokens, hardware security keys, and biometric verification must be prioritized. These are harder to intercept or spoof than SMS codes or push notifications.

Additionally, MFA is being coupled with contextual access controls—monitoring for geographic anomalies, device unfamiliarity, or unusual login patterns to flag suspicious access attempts.

4. Secure Endpoints with EDR and Self-Healing Capabilities

If a phishing attack results in malware deployment or a successful compromise, Endpoint Detection and Response (EDR) platforms play a critical role in limiting impact. These tools monitor all endpoint activity in real time, detect suspicious behavior, and provide rapid investigation and remediation capabilities.

Advanced EDR systems also support self-healing mechanisms—automatically rolling back malicious activity or restoring system configurations to known safe states. This minimizes dwell time and prevents attackers from gaining persistence in the environment.

Modern EDR platforms also come integrated with Security Information and Event Management (SIEM) systems to improve response and automate containment.

5. Implement DNS Filtering to Block Malicious Links

Many phishing attacks rely on users clicking on a link that redirects to a fake login page or initiates a download. DNS filtering solutions stop this chain early by blocking access to known malicious domains—whether embedded in emails, chat messages, or accessed directly via browser.

DNS filtering adds a quiet but powerful layer of protection, preventing users from even reaching phishing infrastructure. It also works regardless of device location—critical in hybrid and remote work environments.

6. Enforce Data Loss Prevention (DLP) Policies

Phishing attacks don’t always end with credential theft. Some aim to exfiltrate sensitive data—customer records, financials, intellectual property.

Data Loss Prevention (DLP) solutions monitor data movement across endpoints, cloud services, and email, ensuring that sensitive information isn’t leaked—intentionally or accidentally.

By defining data classification rules and automated enforcement actions, DLP tools help maintain compliance and protect against insider threats triggered by successful phishing campaigns.

7. Ensure Layered Email Security

Organizations need more than a spam filter. AI-enhanced email security platforms analyze tone, metadata, behavioral patterns, and sender history. They can flag anomalies even when emails look legit on the surface.

Look for solutions that integrate:

• Natural language processing (NLP)
• User behavior analytics
• Threat intelligence feed

8. Embrace Adaptive User Training

Annual phishing simulations aren’t enough. Training must be dynamic and continuous.

• Run realistic simulations using AI-generated templates.
• Provide just-in-time micro-training when users click on risky links.
• Tailor content by department and role—what tricks sales might fall for are different from what works on HR.

9. Adopt a Culture of Reporting and Real-Time Awareness

Technology alone isn’t enough. People remain both a target and a critical line of defense.

Organizations are focusing on practical, real-world security awareness programs that reflect today’s threat environment. These include - Phishing simulations based on current attacker tactics, Role-based training, tailored to department-specific risks, and Just-in-time coaching, triggered after risky user behavior. Reported messages are routed to security teams for triage, helping detect broader campaigns early.

10. Automate Response with SOAR and Incident Playbooks

Speed matters. Once an attack begins, organizations must respond in minutes.

Security Orchestration, Automation, and Response (SOAR) tools help security teams detect, contain, and remediate threats automatically. For phishing, this includes:

• Quarantining the message across multiple inboxes
• Disabling compromised accounts
• Launching threat hunts across connected systems
• Triggering communication protocols with affected teams

Well-defined incident response playbooks, rehearsed regularly, ensure that phishing incidents are handled consistently, with minimal confusion or downtime.
