Phishing Red Flags for Small Businesses

FRFrozen River Security
Annotated phishing email example with red flags

For a small business, phishing usually shows up as something ordinary: a fake invoice, a password reset, a delivery notice, a bank alert, or a message that looks like it came from a vendor. You do not need a security team to catch many of these. You need a short pause before you click, pay, sign in, or download.

A quick visual inspection catches the most important clues: sender mismatch, suspicious link, pressure language, and unexpected attachment.

The red flags that matter most

Before you act, check for:

  • A vendor, bank, payroll, or shipping message you were not expecting.
  • A sender address that is close to the real one, but slightly wrong.
  • A link asking you to sign in from an email instead of your normal bookmark or app.
  • Pressure to pay, approve, reset, or respond right away.
  • An attachment you did not ask for, especially a zip file, invoice, or shared document.

Use a second path

Use the same four-step pause every time: pause, inspect, verify through a second channel, then report the message.

Do not reply to the suspicious message to ask if it is real. Use another path. Open your bank, payroll, email, or vendor portal from a saved bookmark. Call the vendor using the number you already have. Text the employee from your contacts, not the number in the message.

A 60-second routine

  1. Stop before clicking or paying.
  2. Check the real sender address.
  3. Open the service yourself instead of using the email link.
  4. Verify payment or account changes by phone or a known channel.

This does not have to be complicated. Put the routine near the computer where invoices are paid. Use it every time a message asks for money, passwords, codes, or files.
