Why Phishing Is Getting Harder to Spot and What Your Business Can Do About It

For years, employees were taught to look for obvious signs of phishing: poor grammar, strange formatting, suspicious links and emails that simply did not look professional.

Those warning signs still matter, but they are no longer enough.

AI is making it easier for cybercriminals to create polished, convincing messages that appear to come from executives, coworkers, vendors and other trusted sources. Attackers can personalize those messages using information they find online, and AI-generated voices and videos can make impersonation attempts even more believable. Blog-2-Cyber-Myths-Debunked-Oct…

For business leaders, this changes an important cybersecurity assumption. You cannot expect employees to identify every attack simply because something "looks suspicious." Protecting the organization requires multiple layers of security, clear verification procedures and employees who know what to do when something does not feel right.

Phishing Is No Longer Just a Suspicious Email

Email remains a common delivery method, but phishing can reach your employees through text messages, phone calls, QR codes and workplace communication platforms.

Understanding some of the most common approaches can help your team recognize when a routine business interaction deserves additional scrutiny.

Email Phishing

Attackers send messages designed to look like they came from a legitimate company, financial institution, vendor or other trusted source.

The objective may be to convince an employee to click a malicious link, open an attachment, provide login credentials or take another action that gives the attacker access to business information or systems.

AI-Enhanced Phishing

AI allows attackers to create more polished and personalized messages quickly.

Instead of sending the same generic email to thousands of people, an attacker may incorporate information about your company, an employee's responsibilities or an existing business relationship. They may even imitate someone's typical writing style.

That added context can make a fraudulent request seem much more routine.

Spear Phishing

Spear phishing targets a specific individual or organization.

An attacker may research an executive, employee or company before sending the message. Details gathered from company websites, social media and other public sources can then be used to make the request appear legitimate.

Business Email Compromise

Business email compromise, commonly called BEC, typically involves impersonating an executive, employee or vendor to manipulate someone into taking a business action.

That could include changing banking information, redirecting payroll, sending sensitive information or authorizing a fraudulent payment.

These attacks can be especially dangerous because the request may resemble something an employee handles regularly.

Smishing

Smishing takes phishing to text messages.

The employee might receive a message asking them to follow a link, call a phone number or provide account information. Because people often respond quickly to texts, attackers may use urgency to encourage action before the recipient stops to question the request.

Voice Phishing and AI Voice Cloning

Voice phishing, or vishing, uses phone calls or voice messages to impersonate someone the recipient trusts.

AI adds another dimension. Voice-cloning technology can imitate an executive, coworker or other familiar person, making an unusual request sound more credible.

This is why recognizing someone's voice should not automatically be considered sufficient verification for a sensitive request.

QR Code Phishing

QR codes can direct employees to fraudulent websites designed to steal login credentials or other information.

These malicious codes can appear in emails, invoices, documents, posters or even physical packages. Because the destination is not immediately visible before the code is scanned, employees may not realize where they are being sent.

The Better Question Is Not "Will Someone Fall for It?"

Even a careful, well-trained employee can be fooled by a convincing attack.

That means your cybersecurity strategy should not depend on every employee making the right decision every time.

Instead, leadership should ask:

What happens if someone does make a mistake?

A strong phishing defense creates multiple opportunities to prevent, detect or contain an attack before one employee's mistake becomes a larger business problem.

Seven Ways to Make Phishing More Difficult for Attackers

Effective protection combines technology, employee education and clear business procedures.

1. Keep Security Awareness Training Current

Employees should learn about the attacks they are actually encountering today, including AI-generated messages, business email compromise, QR-code phishing and voice cloning.

Training should also teach employees what to do when they are uncertain, not simply how to identify suspicious messages.

2. Use Email Security Beyond Basic Spam Filtering

Modern email security can help identify malicious links, dangerous attachments, impersonation attempts and other suspicious activity before it reaches an employee.

No filtering technology will stop everything, but reducing the number of malicious messages employees have to evaluate lowers the opportunity for human error.

3. Strengthen Account Authentication

Multi-factor authentication adds another barrier if an employee's password is stolen.

Where appropriate, passkeys and hardware security keys can provide stronger protection against certain credential-based phishing attacks.

4. Create Verification Procedures for Sensitive Requests

This is increasingly important as AI makes impersonation more convincing.

Requests involving payments, banking changes, passwords, sensitive information or other high-impact actions should be verified through a separate trusted method.

For example, if an executive sends an unusual request by email, the employee might confirm it through a known phone number or an established internal business system rather than replying to the original message.

The goal is to verify the request independently rather than trusting the communication simply because the name, email, voice or video appears legitimate.

5. Be Thoughtful About Publicly Available Information

Attackers can use information from websites, social media profiles and other public sources to make scams more convincing.

You do not need to disappear from the internet, but employees should understand that information shared publicly can sometimes provide attackers with useful context.

6. Keep Systems and Security Tools Updated

Software updates frequently address vulnerabilities that attackers could use after gaining an initial foothold. Maintaining supported, properly updated systems remains an important part of reducing overall cybersecurity risk.

7. Make Reporting Suspicious Messages Easy

Employees should know exactly how to report something questionable and feel comfortable doing so quickly.

Fast reporting gives the people responsible for cybersecurity an opportunity to investigate the message, determine whether anyone else received it and take action if necessary. These safeguards reflect the practical defenses recommended in the source material.

Your Employees Should Not Be Your Only Line of Defense

Employees play an important role in cybersecurity, but they should not carry the entire responsibility for stopping phishing.

Business leaders should be able to rely on the people responsible for IT and cybersecurity to put appropriate safeguards in place, monitor emerging risks, educate employees and establish clear procedures for sensitive requests.

You should also be able to get straightforward answers to questions such as: Are we adequately protecting email? Is MFA enabled where it should be? Do employees know how to report suspicious messages? What is our procedure for verifying financial requests? What happens if someone's credentials are compromised?

You do not need to understand every technical detail. You need confidence that someone is paying attention and taking ownership.
