Not long ago, phishing emails were easy to identify. These emails contained obvious spelling mistakes, awkward grammar, or strange wording that immediately would raise suspicion. Many originated from questionable email addresses or made unrealistic claims that were easy to dismiss.
But today, that is changing.
Artificial intelligence (AI) has become a powerful tool for businesses looking to improve their productivity. Unfortunately, though, AI is also a very useful tool for cybercriminals seeking new ways to deceive people. With the help of AI, cybercriminals can generate polished, professional-looking emails in seconds, making phishing attempts far more convincing than ever before.
Understanding how AI is changing phishing attacks is an important part of cybersecurity awareness.
Why AI makes phishing more dangerous
Traditional phishing campaigns often relied on sending thousands of generic emails in the hope that someone would click a malicious link or open an infected attachment.
With AI, attacks can be far more sophisticated. With publicly available information from company websites, LinkedIn profiles, social media accounts, news articles, and other online sources, cybercriminals can create highly personalized emails. Instead of a generic message addressed to "customer," an employee might receive an email mentioning a recent conference, current project, or the name of a company executive. The language is flawless, making it more difficult to recognize it as fraudulent.
There are some warning signs to watch for, which can help spot these AI-generated phishing emails. Here are a few.
Warning sign #1: unexpected urgency
Even when an email appears professionally written, urgency remains one of the biggest warning signs.
Messages that demand immediate action, such as paying an invoice, updating account information, purchasing gift cards, or verifying login credentials, should always be viewed with skepticism.
Attackers rely on creating a sense of pressure, so that recipients react before taking time to think the request through thoroughly.
When encountering an urgent request, before taking any action, pause and verify the request through another communication channel (in person, or by phone) if it involves money, sensitive information, or account access.
Warning sign #2: requests for credentials
Legitimate organizations rarely ask users to provide passwords, multifactor authentication codes, or other sensitive login information through email.
If a message asks you to confirm your password, "revalidate" your Microsoft 365 account, or provide security codes, don’t do it! That type of message is a strong indication that someone may be attempting to steal your credentials. When in doubt, visit the organization's website directly rather than clicking a link contained in the email.
Warning Sign #3: Links that don’t quite match
With AI, cybercriminals can write convincing text, but it is the malicious links within the text or email that sends users to a destination.
Before clicking on a link, hover your mouse over any link to preview the actual destination. On mobile devices, press and hold the link to view where it leads before opening it. Watch for subtle misspellings or extra letters in website addresses. A domain that differs by only one letter from a legitimate company can easily fool someone who isn't paying close attention.
Warning sign #4: unusual requests from familiar people
A fast-growing threat is business email compromise (BEC), where attackers impersonate executives, coworkers, or trusted vendors.
AI-generated emails accurately mimic an executive's writing style and tone, making fraudulent requests appear authentic. If a manager suddenly asks for confidential information, wire transfers, or purchases that seem unusual, verify the request with a phone call, text message, or face-to-face conversation before acting.
Warning sign #5: attachments you weren't expecting
Unexpected attachments should always be treated with caution, even if they appear to come from someone you know.
Malicious documents may install ransomware or other malware when opened. AI-generated emails often provide believable explanations for why an attachment needs immediate attention, increasing the chances that someone will open it without questioning its legitimacy. If you weren't expecting the file, confirm with the sender before opening.
AI is also fueling spear phishing
Another concern is the highly targeted attack known as spear phishing.
Instead of sending thousands of identical emails, attackers can use AI to create customized messages for specific individuals within an organization. Finance personnel, HR departments, executives, and IT staff are common targets because they often have access to sensitive information or financial systems.
The more personalized an email appears, the more convincing it can become.
Technology continues to play an important role
Employee awareness is essential, but technology remains a critical first line of defense against AI-enhanced cybercriminal intrusions.
Modern email security platforms can detect suspicious links, scan attachments for malware, analyze sender reputation, and identify unusual communication patterns before messages ever reach employee inboxes.
Additional safeguards such as multifactor authentication, endpoint protection, regular software updates, and advanced threat detection help reduce the damage if an attacker does succeed in obtaining credentials.
No single security tool provides complete protection, but multiple layers working together significantly improve an organization's security posture.
Building a security-conscious culture
Software is a good defense against AI-powered phishing, but it’s not enough by itself. People factor into this equation, too.
Employees should feel comfortable questioning unusual requests, reporting suspicious emails, and verifying information before acting. Regular cybersecurity awareness training helps reinforce these habits and keeps security top of mind.
Rather than worrying about assigning blame, successful organizations encourage employees to report anything that looks suspicious. A single report can prevent an attack from affecting the entire company.
Some final thoughts
For all the good it delivers, AI also gives cybercriminals new tools to create more convincing phishing attacks.
Many of the current best practices are applicable in the fight against AI-enhanced cybercrime: slow down, verify unexpected requests, inspect links carefully, avoid opening suspicious attachments, and never share sensitive information without confirming the source.
But as AI-generated phishing emails become increasingly sophisticated, combining employee awareness with strong security technologies gives businesses their best chance of staying one step ahead of evolving cyber threats.
As a reminder, before clicking any unexpected email:
As we have said previously, AI is the “new frontier” of business technology. It takes extreme vigilance and a strong infrastructure (along with employee training) to stay ahead of cybercriminals who use AI for the wrong purposes.
