How to Train Your Employees to Spot Phishing Attacks (Before It's Too Late)

In 2024, the FBI's Internet Crime Complaint Center reported that Business Email Compromise (BEC) alone caused over $2.9 billion in losses in the United States. The vast majority of successful cyberattacks begin not with sophisticated hacking, but with a single employee clicking a link they shouldn't have.

Phishing works because it exploits human psychology — urgency, authority, curiosity, and trust — rather than technical vulnerabilities. No firewall or antivirus catches 100% of phishing attempts. Your employees are your most critical — and most vulnerable — security layer. Training them effectively is one of the highest-ROI cybersecurity investments your business can make.

What Is Phishing, Exactly?

Phishing is a cyberattack in which an attacker impersonates a trusted entity — your bank, Microsoft, your CEO, a vendor — to trick you into revealing credentials, transferring money, or installing malware.

Spear Phishing

Unlike generic phishing (mass emails sent to millions of addresses), spear phishing is targeted. The attacker researches the victim in advance — using LinkedIn, company websites, and social media — and crafts an email that appears highly personalized and credible. A spear phishing email might reference a real project your company is working on or use the name of an actual colleague.

Whaling

Whaling is spear phishing targeting high-value individuals: executives, CFOs, legal counsel, or IT administrators with elevated system access. These attacks often impersonate other executives ("CEO fraud") or boards of directors. The goal is typically a fraudulent wire transfer or the theft of sensitive credentials.

Business Email Compromise (BEC)

BEC is the most financially damaging phishing variant. In a typical BEC attack:

1. An attacker gains access to a legitimate email account (often through credential phishing)
2. They monitor the mailbox silently for weeks, learning the company's financial processes, vendors, and communication patterns
3. At the right moment, they insert themselves into an existing email thread and redirect a payment to their own account
4. By the time the fraud is discovered, the money is gone

Chicago-area real estate closings, law firms, and manufacturing companies have all been victimized by BEC attacks.

Red Flags Every Employee Should Know

Train your team to pause and verify before acting whenever they see:

Urgency and Pressure

• "Act immediately or your account will be locked"
• "This invoice is overdue — process payment today"
• "I need this wire sent before 3 PM"

Attackers create artificial urgency to prevent victims from thinking critically. A legitimate business request can always wait 10 minutes for you to verify it through a different channel.

Sender Address Spoofing

• The display name says "Microsoft Support" but the email is from support@micros0ft-helpdesk.ru
• An email appears to come from your CEO but the actual address is ceo@your-company.com.phishing.net
• The domain is off by one character: paypa1.com, arnazon.com

Always check the actual email address, not just the display name. On mobile devices, this requires an extra tap to reveal the true sender.

Suspicious Links

• Hover over any link before clicking — the displayed URL should match the destination URL
• Shortened URLs (bit.ly, tinyurl.com) hide the true destination
• Legitimate companies rarely use shortened URLs in business communications
• URLs with excessive subdomains: login.microsoft.com.verify-account.phishing.net is not Microsoft

Unusual Attachments

• Unexpected attachments, even from known senders (their account may be compromised)
• Password-protected ZIP files sent without prior warning
• Office documents asking you to "Enable Content" or "Enable Macros" — these execute malicious code

Requests That Bypass Normal Process

• "Don't go through the normal approval process for this one"
• "Don't mention this to anyone else"
• Wire transfer requests that arrive by email alone, without prior phone confirmation

Any request to transfer money or change payment information should be verified by calling the requestor directly using a phone number you already have — not one provided in the email.

Real-World BEC Examples

The Vendor Impersonation Attack: A Chicago accounting firm received an email from a long-term vendor stating their banking information had changed. The email looked identical to the vendor's real communications. The next three payments — totaling $87,000 — went to a fraudulent account before the discrepancy was caught.

The CEO Wire Request: A manufacturing company's CFO received an email from the CEO's name asking for a $45,000 wire to a new vendor for a confidential acquisition. The CFO, not wanting to bother the CEO during a busy time, processed the request. The real CEO had no idea until the next day.

Both of these attacks were preventable with proper training and verification procedures.

Simulated Phishing Tests: The Most Effective Training Tool

The research is clear: employees who have been caught by a simulated phishing test are significantly more vigilant afterward. Simulated phishing programs work by:

1. Sending realistic phishing emails to employees without warning
2. Tracking who clicks links, submits credentials, or opens attachments
3. Immediately delivering targeted training to employees who fall for the simulation
4. Tracking improvement in click rates over time

Platforms like KnowBe4, Proofpoint Security Awareness Training, and Microsoft Attack Simulator (included in Microsoft 365 Business Premium) make this accessible for small businesses. TechniWorx manages these programs for clients throughout the Chicago area.

What Good Results Look Like

• Average click rate for untrained organizations: 25–35%
• After 90 days of training: typically 5–10%
• After 12 months of ongoing training: typically 2–5%

Even 2% sounds small — but in a company of 50 employees sending and receiving hundreds of emails daily, that's still meaningful exposure. The goal is continuous improvement, not perfection.

Building a Reporting Culture

Many employees who recognize a phishing attempt don't report it because they don't know how, don't think it matters, or fear being judged for almost clicking. Changing this requires:

• A simple, visible reporting mechanism: Microsoft 365 and Google Workspace both have one-click reporting add-ins for suspicious emails
• Positive reinforcement: Praise employees who report suspicious messages — even if it turns out to be legitimate
• Closed-loop feedback: Tell employees what happened with their report ("That was a simulated test — great catch!" or "We confirmed that was malicious and blocked the sender")
• No blame for almost-clicking: Create psychological safety around reporting mistakes

An organization where employees actively report suspicious emails is far more resilient than one where people stay quiet about near-misses.

Putting Training Into Practice

A comprehensive security awareness program includes:

• Monthly phishing simulations with immediate training for clickers
• Short video modules (5–10 minutes) on rotating security topics
• Annual security policy review and signed acknowledgment
• Onboarding training for all new hires before they have access to systems

The investment is modest — typically $25–50 per employee per year for a managed program — and the ROI on preventing a single BEC incident is enormous.
