📞 Cybersecurity for Small Businesses: The Call That Triggered a Costly Mistake

Dr. Karen Patel, an administrator at Westview Medical Group, received an urgent voicemail from someone claiming to be with MedEquip Solutions, a vendor she trusted. The caller warned of an overdue invoice that needed immediate payment to avoid supply delays.

Shortly after, Dr. Patel received a follow-up email from billing@medequip-solutions.com. It looked legitimate and included a payment link. Wanting to avoid disruptions, she called the number from the voicemail, spoke to a representative, and processed an ACH transfer — a direct bank-to-bank payment — for $18,750.

Days later, the real MedEquip Solutions reached out about a different outstanding invoice. That’s when Dr. Patel realized she had been scammed.

🕵️‍♀️ What Happened? A TOAD Attack in Action

This was a TOAD attackTelephone-Oriented Attack Delivery. Cybercriminals used:

  • Voicemail phishing to create urgency
  • Email spoofing to mimic a trusted vendor
  • Caller ID spoofing to appear legitimate
  • ACH payment requests, which are difficult to reverse

They exploited trust, urgency, and familiarity — and it worked.


🚩 Cybersecurity for Small Businesses: Red Flags You Shouldn’t Ignore

  • Urgency: The caller and email both emphasized immediate payment to avoid supply issues.
  • Unverified contact info: Dr. Patel used the phone number and email provided in the scam, not ones she already trusted.
  • ACH transfer: Unlike credit card payments, ACH transfers are harder to trace and reverse.

How to Protect Your Business

At PhasedLogix, we help businesses like yours stay ahead of cyber threats. Here’s what we recommend:

Always Verify Financial Requests

Use known contact information — not what’s provided in a suspicious message. Call your vendor directly using a number from your records or their official website.

Be Wary of Urgency

Scammers often create pressure to act fast. Take a moment to verify before you respond.

Educate Your Team

Cybersecurity is a team effort. Make sure your staff knows how to spot phishing attempts and suspicious behavior.
