Imagine losing $31,583 every minute. That’s how much cybercrime cost American businesses in 2024, according to the FBI’s Internet Crime Complaint Center. Phishing was one of the top threats behind that number. If you're still thinking phishing is just about misspelled emails from a Nigerian prince, you're dangerously underestimating today’s threat.

This post will walk through educating your MSP’s clients on why phishing still works in 2025, how attackers have leveled up their game, and most importantly, how you can defend against it. We'll break it down simply, give you tools to spot it, and explain the role DNS-layer protection plays in stopping these attacks before they start.

Why Phishing Still Works

Phishing isn’t a new threat. But it’s still the most effective one. Why?

  • We trust people. Humans are wired to believe the sender, especially if the message looks like it’s from someone they know.

  • We respond quickly. Attackers create a sense of urgency with "Your account is compromised!", "Payment overdue!" to trigger impulse clicks.

  • We assume email is secure. Most users don’t know how easy it is to spoof email addresses or clone login pages.

  • Spam filters aren’t foolproof. Especially against well-crafted, low-volume spear phishing emails that slip under the radar.

Cybercriminals rely on human behavior. That’s the real vulnerability, not the tech.

Modern Phishing Tactics

Today’s phishing campaigns are polished, targeted, and often powered by AI. Here are the most dangerous methods:

  • AI-generated spear phishing
    • Attackers now use AI to mimic tone, grammar, and language from previous emails. These messages sound just like your boss.

  • Deepfake vishing
    • Audio phishing calls are now enhanced with voice cloning. Imagine hearing your CEO’s voice asking you to send a payment.

  • Look-alike domains and fake login pages
  • QR code phishing
    • Victims scan a QR code that leads to a malicious site, skipping traditional link-based detection.

How to Recognize a Phishing Attempt

Your clients don’t need a cybersecurity degree to spot most phishing attacks. They just need a system. Here's the checklist:

  • Is the sender address legit? Hover to see the real email address.

  • Were you expecting this email? Random attachments from "HR" should raise flags.

  • Check the tone and grammar. Awkward language or urgency should prompt caution but is less helpful with new AI technology.

  • Requests for sensitive info? Never send credentials or payment info via email.

  • Hover over links. Does the destination match the text? If not, don’t click.

Training your clients and staff to use this checklist can make the difference between a normal day and a data breach.

Layered Defense Strategy

No single tool stops phishing. You need layers.

  1. Email Security – Filters and threat intel help block basic attacks.

  2. MFA (Multi-Factor Authentication) – Stops damage even if credentials are stolen.

  3. Endpoint Protection – Detects malware if someone clicks a bad link.

  4. Security Awareness Training – Prepares your humans.

  5. DNS-layer Protection – Blocks access to malicious domains before users even reach them.

Each layer reduces risk, but together they’re a fortress.

The Role of DNS in Blocking Phishing

Here’s a simple way to explain DNS:

DNS is like the internet’s GPS. Every time you click a link or visit a website, your device asks a DNS server for directions.

Now imagine your GPS said, "Hey, that’s a dangerous neighborhood. I’m not taking you there."

That’s what DNS filtering does. If you try to visit a known phishing domain, DNS protection blocks it. Instantly.
