Artificial intelligence is changing a basic assumption businesses have relied on for years: if an email sounds like your boss, a caller sounds like your vendor or a video looks like someone you know, there is a good chance it is really them.
That assumption is becoming increasingly risky.
AI can help attackers create convincing emails, imitate voices and produce realistic images and video at a speed and scale that wasn’t previously possible. At the same time, employees are introducing another type of AI risk by using public AI tools for everyday work without always considering what happens to the information they enter.
The answer isn’t to teach employees to become experts at detecting AI. As AI-generated content improves, identifying a fake based on how it looks, sounds or reads will become increasingly unreliable. Businesses need verification procedures and security controls that still work when the person on the other side of an interaction appears completely legitimate.
1. AI impersonation makes familiar voices less trustworthy
Imagine someone in accounting receives a call from an executive asking for an urgent wire transfer. The voice sounds right. The caller knows the name of the vendor, references a current project and explains why the payment can’t wait.
Traditionally, recognizing the executive’s voice might have provided some reassurance. With AI voice cloning, it shouldn’t.
The same problem extends beyond phone calls. Attackers can use synthetic audio, images and video to strengthen impersonation attempts and make fraudulent requests more convincing. That changes what businesses should rely on when verifying sensitive transactions.
For financial transfers, payroll changes, password resets, requests for sensitive information and other high-risk actions, verification should happen through a separate, trusted channel. Instead of replying to the message or calling a number provided by the requester, employees should use contact information already on file or follow an established approval process.
The important shift is simple: verify the request, not the realism of the person making it.
2. AI-generated phishing removes many of the old warning signs
Employees have been told for years to look for spelling mistakes, awkward wording and strange formatting in phishing emails. Those clues haven’t disappeared entirely, but businesses shouldn’t depend on them.
Generative AI can produce polished messages in seconds. Attackers can create emails that sound professional, incorporate information about a company or employee and closely resemble ordinary business communication. An email doesn’t have to look suspicious to contain a dangerous request.
That’s why employees should pay attention to what a message is asking them to do. A sudden change in banking information, an unexpected login request, pressure to bypass a normal procedure or a request for confidential information deserves verification even when the message itself looks flawless.
This is also why email security needs to extend beyond traditional spam filtering. Modern phishing defenses can analyze factors such as sender identity, behavior and message intent instead of relying exclusively on obvious malicious links, attachments or keywords.

3. AI creates risk even when there is no attacker
Not every AI cybersecurity risk comes from a cybercriminal. Sometimes an employee can expose sensitive information simply by trying to get work done faster.
An employee might ask an AI tool to summarize a financial report, rewrite a customer email, analyze meeting notes or troubleshoot proprietary code. The task may seem harmless, but the information entered into the tool could include customer records, financial information, intellectual property, credentials or other confidential business data.
This is often referred to as shadow AI: employees using AI applications without formal approval or oversight from the organization.
Banning AI altogether isn’t necessarily the answer. Businesses should establish clear rules about which AI platforms employees may use, what information can be entered into them and what types of company or customer data should never be shared with a public AI tool.
Employees should not have to guess whether an AI application is appropriate for a particular task.

Stop trying to spot AI. Build processes that account for it.
AI-generated scams will continue to improve. The security strategy can’t be hoping employees will always notice something strange about a voice, video or email.
Instead, businesses should establish procedures that remain effective even when a fake is extremely convincing. That includes requiring independent verification for financial and account changes, using strong multi-factor authentication, defining which AI tools employees are allowed to use, limiting access to sensitive information and making sure employees know exactly how to report suspicious activity.
Technology matters too. Advanced email protection, identity security and monitoring can help identify suspicious behavior that an employee may not recognize from the message itself. The goal is to create multiple opportunities to stop an attack rather than depending on one person to recognize a fake at exactly the right moment.

Is your business prepared for AI-powered cyber threats?
AI hasn’t made the fundamentals of cybersecurity obsolete. It has made some of them more important.
Businesses still need strong authentication, controlled access, employee awareness, monitoring and clear procedures for handling sensitive requests. What has changed is how convincing an attack can look before those safeguards are tested.
If your cybersecurity strategy still depends heavily on employees recognizing when something “looks suspicious,” it’s worth taking another look.
