Phishing is still the number one way businesses get breached, and in 2026 the emails are far harder to spot than the clumsy “Nigerian prince” messages of a decade ago. Attackers now use AI to write flawless, personalized messages, spoof your vendors, and even mimic your CEO’s writing style. For Boston small and mid-sized businesses, a single click can mean ransomware, a drained bank account, or a compliance incident. Here is how modern phishing works and how to defend against it.

What Modern Phishing Looks Like

The grammar mistakes are gone. Today’s phishing emails reference real projects, real coworkers, and real vendors, because attackers research your company on LinkedIn and your website first. The most common forms we see hitting Massachusetts businesses are: business email compromise (a spoofed message from an executive asking for a wire transfer or gift cards), vendor fraud (a fake invoice or a “new banking details” request from a supplier), and credential harvesting (a link to a fake Microsoft 365 login page that steals your password).

The Warning Signs to Train Your Team On

Urgency and secrecy

“I need this done in the next 10 minutes and I’m going into a meeting” is a classic pressure tactic. Legitimate requests can wait for verification.

A change to payment details

Any email that changes bank account or payment information should be verified by phone using a known number, never the number in the email.

Slightly wrong addresses and links

Hover over links before clicking. A login page at microsoft-365-login.com is not Microsoft. A message from [email protected] (with a zero) is not your vendor.

Unexpected attachments

Invoices, voicemails, and shared documents you weren’t expecting deserve a second look, especially if they ask you to “enable content” or sign in to view.

Training Is Your First Line of Defense

Technology can’t catch everything, which is why the human layer matters. Ongoing security awareness training with simulated phishing tests turns your employees from your biggest risk into your best sensor. The goal isn’t to trick people, it’s to build the habit of pausing and verifying. Businesses that run quarterly simulations see click rates drop dramatically within a year.

The Technical Controls That Stop Phishing

Training reduces risk, but layered technology catches what slips through:

Multi-factor authentication means a stolen password alone isn’t enough to get into your accounts. Advanced email filtering blocks known malicious senders and scans links and attachments before they reach the inbox. DNS and web filtering stops users who do click from reaching the malicious site. And endpoint detection and response catches malware that makes it onto a device. We build all of this into our cybersecurity services, and it’s increasingly what cyber insurance carriers require too.

What to Do If Someone Clicks

Mistakes happen. The key is speed: disconnect the device from the network, change the affected passwords, and call your IT provider immediately. A fast response often means the difference between a near-miss and a full breach. This is exactly the kind of incident a managed IT partner is built to handle.
