What Is Phishing? A Clear Guide to Spotting Fake Emails Before You Click

You open your email. There's a message from your bank asking you to verify your account. Another from a delivery service about a package. One more from IT asking you to reset your password by the end of the day.

They all look real. The logos match. The language sounds official. But one of them is fake. And if you click, you just gave an attacker exactly what they wanted. So, what is phishing, and how can you protect yourself and your business?

Phishing is one of the most common cyberattacks in the world, and it works because these emails are designed to look legitimate, create urgency, and get you to act before you think.

The good news? Once you know what to look for, phishing emails are much easier to spot.

This guide explains what phishing is, how it works, what the red flags are, and what to do if you think you clicked on something you shouldn't have.

What Is Phishing?

Phishing is a cyberattack where someone pretends to be a trusted person, company, or service to trick you into sharing sensitive information or clicking a malicious link.

The goal is usually to:

• Steal login credentials like usernames and passwords.
  
• Capture financial information such as credit card or bank account details.
  
• Install malware on your device.
  
• Gain access to your company's systems to steal data, deploy ransomware, or move deeper into the network.
  

Phishing most often happens through email, but it can also occur via text message (smishing), phone call (vishing), or fake websites.

The reason phishing works so well is simple: it targets people, not technology. Even the best firewall won't stop a user from entering their password on a fake login page.

What Is Phishing and Why It Matters to Your Business

For small and midsize businesses, phishing is one of the top entry points for cyberattacks.

One clicked link can lead to:

• Compromised email accounts that attackers use to send more phishing emails to clients, vendors, or coworkers.
  
• Stolen credentials that give attackers access to financial systems, cloud platforms, or internal files.
  
• Ransomware infections that lock your systems and demand payment to restore access.
  
• Business email compromise (BEC) scams where attackers impersonate executives to request wire transfers or sensitive data.
  
• Compliance violations if protected data is exposed, especially in healthcare, legal, or financial services.
  

Phishing doesn't just affect the person who clicked. It can disrupt operations, damage client trust, trigger regulatory reporting requirements, and cost thousands of dollars to recover from.

That's why learning to spot phishing emails is one of the most practical cybersecurity skills every employee can develop.

What Is a Phishing Email? How to Spot the Red Flags

Phishing emails are getting more sophisticated, but they still follow recognizable patterns. Here are the most common warning signs…

The Sender Email Address Doesn't Match

One of the easiest ways to spot a phishing email is to check the sender's email address closely.

A phishing email might display a name like "Microsoft Support" or "Your Bank," but when you look at the actual email address, it says something like:

• noreply@micros0ft-support.com
  
• account-security@bankofamerica.verify.net
  
• payroll@yourcompany.co.za
  

Look for:

• Misspellings in the domain name.
  
• Extra words or characters added before or after the real domain.
  
• Unusual domain extensions like .net, .co, or country codes that don't match the company.
  
• Generic email services like Gmail, Yahoo, or Outlook when the message claims to be from a business.
  

A real email from Microsoft might come from @microsoft.com. A phishing email might come from @micros0ft-security.com or @microsoft.services-alert.com.

The Message Creates Urgency or Fear

Phishing emails often try to make you act fast before you have time to think.

Common tactics include:

• "Your account will be locked in 24 hours."
  
• "Unusual activity detected. Verify your identity now."
  
• "Your payment was declined. Update your billing information immediately."
  
• "You missed an important delivery. Click here to reschedule."
  
• "Action required: Your password expires today."
  

If an email makes you feel panicked or pressured, slow down. Legitimate companies rarely threaten to lock your account without warning, and they won't ask you to verify sensitive details through email.

The Greeting Is Generic

Phishing emails often use vague greetings because the attacker doesn't know your name.

Watch for openings like:

• "Dear Customer"
  
• "Valued User"
  
• "Hello"
  
• "Attention Account Holder"
  

Your bank, your cloud provider, and your coworkers usually know your name. If the email doesn't use it, that's a red flag.

The Link Doesn't Go Where It Says It Does

Hover over any link in the email before you click it. Most email programs will show you the actual URL.

Even if the link text says "www.yourbank.com," the real destination might be www.yourbank-login.phishingsite.com.

Phishing links often:

• Mimic real websites with small changes like extra letters, hyphens, or different domain extensions.
  
• Use URL shorteners to hide the real destination.
  
• Include random strings of numbers or letters after the domain.
  

The email says: "Click here to reset your Microsoft password." But when you hover, the link shows: http://login-microsoft.verify-account482.com/reset. That's not Microsoft.

The Email Asks for Sensitive Information

No legitimate company will ask you to provide your password, Social Security number, credit card details, or bank account information through email.

If an email asks for:

• Login credentials
  
• Payment information
  
• Personal identification numbers
  
• Security question answers
  

It's almost certainly phishing.

The Attachments Look Suspicious

Be cautious with email attachments, especially if you weren't expecting them.

Phishing emails often include:

• Fake invoices or receipts with malware hidden inside.
  
• .zip, .exe, or .js files that can install malicious software when opened.
  
• Documents that ask you to enable macros to view the content.
  

If an attachment seems unusual or unexpected, don't open it. Verify with the sender through a separate communication method first.

What to Do If You Think You Clicked a Phishing Link

If you think you clicked on a phishing link or entered your credentials on a fake site, act quickly.

• Disconnect from the internet to limit potential damage.
  
• Change your password immediately for the affected account and any other accounts using the same password.
  
• Report the incident to your IT team or managed service provider right away.
  
• Watch for any unusual activity in your accounts, such as unauthorized logins, password reset requests, or strange emails sent from your account.
  
• Run a security scan on your device if you downloaded an attachment or clicked a suspicious link.
  

The faster you respond, the more you can limit the damage.

How Businesses Can Reduce Phishing Risk

Spotting phishing emails is an important skill, but it's not the only line of defense. Taking precautions to stop unwanted emails is the next step.

Businesses should also:

• Use email filtering and security tools that flag or block known phishing attempts
  
• Enable multi-factor authentication (MFA) on all accounts so stolen passwords alone aren't enough to gain access
  
• Train employees regularly on how to recognize phishing emails and report them
  
• Establish verification processes for financial requests, password resets, and sensitive data sharing
  
• Monitor for compromised credentials using dark web monitoring and security alerts
  
• Test your team with simulated phishing campaigns to see how well they recognize real threats
