Most cyberattacks don’t begin with a hacker breaking through a firewall.
They begin with an email.
It may look like a message from Microsoft telling you that your password is about to expire. It might appear to come from your bank, a vendor, a coworker, or even your boss. Perhaps it contains an invoice you weren’t expecting or a notice that someone has shared a document with you.
And all it asks you to do is click.
That’s what makes phishing email so dangerous.
The Criminal Doesn’t Have to Defeat Your Security
Modern businesses can have multiple layers of cybersecurity protecting their networks—firewalls, security patching, antivirus protection, endpoint detection, application controls, email filtering, and more.
At NetSystems, we believe strongly in this layered approach to security.
But attackers understand something very important: sometimes it’s easier to convince a person to open the door than it is to break through it.
That’s the purpose of phishing.
Rather than attacking the technology directly, the criminal attacks the person using it.
Phishing Has Become Much More Convincing
Years ago, phishing emails were often easy to recognize.
They contained misspelled words, strange grammar, suspicious email addresses, and obviously fraudulent requests.
Those emails still exist, but today’s phishing attacks can be remarkably convincing.
Criminals can copy company logos, reproduce Microsoft 365 login pages, imitate legitimate email notifications, and create messages that appear to come from people you know.
Artificial intelligence is making this problem even more challenging. Attackers can now create professional, grammatically correct messages in seconds.
The old advice of simply looking for spelling mistakes isn’t enough anymore.
What Happens When You Click?
Clicking a phishing link doesn’t necessarily mean something bad immediately happens.
The real danger is usually what happens next.
You may be taken to a website that looks exactly like the Microsoft 365 login page. You enter your email address and password, and the page tells you that your password was incorrect.
You try again.
Meanwhile, you may have just handed your credentials to a criminal.
Depending upon the attack, criminals may then attempt to access your email, steal information, impersonate you, reset passwords for other services, or use your account to send additional phishing messages to your coworkers and customers.
One compromised account can quickly become a much larger problem.
Phishing Usually Creates a Sense of Urgency
One of the most effective weapons in a phishing attack isn’t technical at all.
It’s urgency.
Your password expires today.
Your account will be disabled.
Payment is required immediately.
You have a secure document waiting.
The CEO needs this handled right away.
The attacker wants you reacting instead of thinking.
Whenever an email creates pressure to act immediately—especially when it involves money, passwords, confidential information, or changing account information—slow down and verify the request.
Thirty seconds of verification can prevent days or weeks of recovery.
Be Especially Careful With Financial Requests
Some of the most damaging phishing attacks involve what is commonly called Business Email Compromise.
An employee may receive what appears to be an email from an executive asking for a wire transfer.
An accounting employee may receive a message supposedly from a vendor announcing that its banking information has changed.
Someone in payroll might receive a request to change an employee’s direct-deposit information.
These requests may look completely legitimate.
That’s why financial changes should never be trusted based solely on an email.
Verify the request using a known telephone number or another communication method that you already trust—not a phone number contained in the suspicious message.
Your Password Isn’t the Only Thing Criminals Want
Phishing isn’t limited to stealing passwords.
Attackers may attempt to obtain:
- Microsoft 365 credentials
- Banking information
- Credit-card information
- Employee information
- Patient information
- Social Security numbers
- Vendor payment information
- Remote-access credentials
For healthcare organizations, a successful phishing attack can become particularly serious because compromised systems or email accounts may contain protected health information.
What begins as a single email can potentially become a security incident, business interruption, or data breach.
Technology Matters—But So Does the Person Behind the Keyboard
There is no single cybersecurity product that can stop every phishing attack.
That’s why effective cybersecurity requires layers.
A properly protected workstation and network may include perimeter firewall protection, current security patches, Microsoft Windows Defender, advanced threat detection such as Huntress, application control such as ThreatLocker, email security, multifactor authentication, backups, and continuous monitoring.
Each layer makes an attack more difficult.
But there is another layer that is just as important:
You.
Employees who recognize suspicious messages and know when to stop and ask questions are an important part of an organization’s cybersecurity defense.
Before You Click, Ask Yourself Three Questions
When something about an email doesn’t feel right, ask:
Was I expecting this?
Is this asking me to do something unusual?
Can I verify this another way?
If you’re unsure, don’t click the link.
Don’t open the attachment.
Don’t reply to the message asking whether it’s legitimate.
Instead, contact the supposed sender through a telephone number, website, or communication method that you already know is legitimate.
And if your company has an IT support provider, send the message to them for review.
We would much rather examine 100 legitimate emails than respond to one compromised account.
Cybersecurity Is a Shared Responsibility
The goal isn’t to make employees afraid of email.
It’s to make them appropriately skeptical.
Most of us process dozens or even hundreds of electronic messages every day. Criminals understand that eventually we’re going to be busy, distracted, or in a hurry.
They’re counting on that moment.
Technology provides important protection, but cybersecurity ultimately works best when good technology is combined with informed people.
So the next time an unexpected email tells you that something is urgent and asks you to click a link, open an attachment, enter a password, or send money, remember:
Stop. Look. Verify.
That extra moment may be the thing that prevents the next cyberattack.
