For years, one of the easiest pieces of cybersecurity advice to give employees was:
Look for spelling mistakes.
Bad grammar, strange wording, awkward sentences, and obvious typos were all signs that an email might not be what it claimed to be.
That advice made sense.
But there's a problem.
Cybercriminals have AI now, too.
And that means the phishing email sitting in someone's inbox may be perfectly written.
No typos.
No strange grammar.
No awkward greeting.
It may even sound remarkably like the person it's pretending to be.
The old warning signs haven't completely disappeared. But businesses need to teach employees what to look for now.
Generative AI makes it incredibly easy to create polished text.
That's useful when legitimate businesses use it to help draft documents, summarize information, or improve communication.
Unfortunately, criminals can use the same capability.
The source article cites warnings from both the UK's National Cyber Security Centre and the FBI about AI helping criminals create more believable phishing messages without the spelling and grammatical mistakes that once gave them away.
Instead of spending time carefully writing an email, an attacker can generate one in seconds.
They can ask AI to make it:
Professional.
Friendly.
Urgent.
Financial.
Technical.
Or written to sound like it came from an executive, supplier, or another trusted person.
Suddenly, "This email is written too well to be a scam" becomes a dangerous assumption.
This is where things get even more convincing.
Think about how much information exists publicly about your business.
Your website might list your employees.
LinkedIn can reveal job titles.
Social media posts can show events, projects, customers, vendors, or new hires.
Press releases may announce partnerships and business developments.
None of that information necessarily seems dangerous on its own.
But combine it with AI, and an attacker can potentially create a much more believable story.
Imagine someone in accounting receives this:
"Hi Sarah, we're finalizing the invoice for the Smith project. We've recently changed banks, so please use the updated account details attached for this month's payment."
The names are right.
The project is real.
The writing looks professional.
The request seems plausible.
There's just one problem.
The supplier didn't send it.
That's the kind of phishing attack businesses need to prepare employees for.
This may be the single most important lesson to teach your team.
Instead of asking:
"Does this email look like a scam?"
Ask:
"What is this email asking me to do?"
Because even when the writing looks perfect, the request can reveal the danger.
Pay particular attention when an email asks someone to:
The supplied article makes the same point: the dependable warning signs are increasingly found in the action being requested, rather than how well the email is written.
Cybercriminals don't want employees thinking carefully.
They want action.
That's why phishing messages so often create urgency.
"Payment must be made today."
"Your account will be suspended."
"I need these gift cards before the meeting."
"Update the banking information immediately."
"Your password expires in 30 minutes."
The objective is simple:
Create enough pressure that the employee reacts before checking.
A good cybersecurity culture teaches the opposite behavior.
The more urgent a sensitive request feels, the more important it is to verify it.
Display names can be deceptive.
An email might appear to come from:
John Smith – ABC Supplier
But that doesn't necessarily mean John's real email account sent it.
Employees should look at the full email address.
Sometimes the difference is obvious.
Other times, it may be incredibly subtle—a changed letter, an extra character, or a domain designed to resemble the legitimate company's address.
The supplied article specifically identifies a mismatch between the display name and actual email address as a warning sign employees should continue watching for.
One business rule can stop a potentially devastating scam:
Never change payment or banking information based only on an email.
If a supplier emails new banking details, verify the change another way.
Call a trusted contact using a phone number you already have.
Don't use a telephone number supplied in the suspicious email.
Don't simply reply asking whether the change is genuine.
If an attacker has compromised the supplier's email account, they may be able to answer that reply too.
Use an independent communication channel.
That extra two-minute check could prevent thousands of dollars from being sent to a criminal.
Your business should absolutely have strong email security.
Spam filtering, phishing protection, attachment scanning, link protection, and other security controls can stop enormous amounts of malicious email before employees ever see it.
But no filter catches everything.
The source article points out that a well-written personalized message with no obviously malicious attachment or link may be much harder for automated systems to recognize.
That's why cybersecurity needs layers.
Technology is one layer.
Your employees are another.
Here's where this gets particularly important.
The same technology helping criminals create believable emails can also make other impersonation attacks more convincing.
The source discusses AI-assisted voice cloning and warns that criminals may create audio that sounds like someone the victim recognizes.
Imagine receiving a voicemail that sounds like your boss:
"I need you to make this payment immediately. I'm heading into a meeting, so don't call me back."
That voice sounding familiar isn't enough to prove the request is genuine.
The same rule applies:
Verify sensitive requests through a trusted, independent channel.
Call the person using the number you already have.
Ask them directly.
A few moments of verification can prevent a major incident.
Cybersecurity training can become overwhelming when employees are given dozens of things to remember.
So make the important rules easy.
For example:
Any unusual payment request or banking change gets independently confirmed.
Never send passwords or verification codes by email.
Urgency should increase scrutiny, not decrease it.
Don't automatically trust an unexpected attachment, link, login request, or change in process.
Employees should know exactly who to contact when something feels wrong.
Simple rules are much easier to remember when someone's inbox is full and they're trying to get through a busy workday.
There's another important part of phishing protection that businesses sometimes overlook.
Employees need to feel comfortable reporting suspicious messages.
They shouldn't worry that they're wasting someone's time.
They shouldn't feel embarrassed because they aren't sure.
And they definitely shouldn't hide a mistake because they're afraid they'll get in trouble.
A healthy security culture encourages people to say:
"This looks strange. Can you check it?"
You would much rather investigate 20 legitimate emails than discover the 21st was a real attack after money or information was stolen.
Passwords shouldn't be your only protection.
The source recommends phishing-resistant MFA or passkeys so that stealing someone's password doesn't automatically give an attacker access to the account.
Strong authentication adds another barrier between an attacker and your business systems.
It doesn't eliminate phishing.
But combined with email protection, access controls, monitoring, employee awareness, and good security policies, it makes your organization a much harder target.
If your employee security training still focuses heavily on:
"Look for spelling mistakes."
It's time for an update.
Those mistakes may still appear in some scams.
But they aren't something you can rely on anymore.
Modern phishing awareness should teach employees to evaluate:
Who is asking?
What are they asking for?
Is this normal?
Is there pressure to act quickly?
Can I verify the request another way?
Those questions remain useful even when AI writes the perfect email.
Speed matters.
If an employee clicks something suspicious, enters their credentials, sends sensitive information, approves an MFA request, or makes a payment they now believe was fraudulent, contact your IT team immediately.
Don't wait to see what happens.
Depending on the incident, your IT team may need to:
Reset credentials.
Revoke active sessions.
Secure affected accounts.
Investigate mailbox activity.
Check endpoints.
Review forwarding rules.
Look for signs of unauthorized access.
The earlier the incident is reported, the better chance you have of limiting the damage.
Sometimes, but you shouldn't rely on it. AI can help attackers produce polished, professional-looking messages. Pay more attention to what the email asks you to do.
Requests involving money, changed bank details, passwords, verification codes, sensitive information, unexpected links or attachments, and unusual urgency should all receive additional scrutiny.
Good email security can block many threats, but it won't catch every sophisticated or highly personalized phishing message. Businesses need both technical protection and employee awareness.
Don't act on the request. Verify it through a trusted channel, such as calling the person using a known phone number, and report the message to your IT team.
Yes. Establishing a policy requiring independent verification of banking or payment changes can help protect against invoice and supplier impersonation scams.
Phishing hasn't disappeared.
It's gotten better at pretending to be legitimate.
The email might be perfectly written.
The company name might be right.
The person's job title might be accurate.
The request might even reference something real.
So don't train your employees to look only for mistakes.
Train them to recognize behavior.
Money.
Passwords.
Payment changes.
Unexpected attachments.
Urgency.
Unusual requests.
And give them permission to stop and verify before doing anything.
Because when phishing emails look real, a culture of verification becomes one of your strongest defenses.
