Phishing uses trusted-looking messages and urgency to persuade someone to click, sign in, share information, approve MFA, or send money.

Key takeaways

What to know before you act

  • Phishing uses urgency, authority, or curiosity to get someone to click, sign in, open a file, or approve a payment.
  • Messages can arrive by email, text, phone, collaboration apps, or QR codes, and may come from a legitimate but compromised account.
  • Fast reporting is as important as avoiding clicks—it lets the organization block a campaign and reset exposed accounts.

Why it matters

What business leaders should understand

Phishing remains effective because it targets normal business processes such as invoices, document sharing, password resets, and executive requests.

The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.

What modern phishing looks like

Phishing has moved well beyond misspelled emails. Attackers copy real sign-in pages, reference current invoices or shipments, send messages from compromised vendor accounts, and use text messages, phone calls, or QR codes to move the target outside protected email channels.

Some campaigns are designed to capture a password and the MFA code at the same time, or to trick a user into approving a sign-in prompt. Others aim directly at payment processes by impersonating a vendor or executive.

  • Shared-document or voicemail notifications that lead to a sign-in page.
  • Invoice, payroll, or bank-detail change requests.
  • Urgent requests from an executive to buy gift cards or send funds.
  • Calls or texts claiming to be IT support and asking for a code or remote access.

How to respond to a suspicious message

Do not click links, open attachments, scan QR codes, or reply. Verify the request through a known phone number or by navigating directly to the service. Report the message using the organization's reporting button or process so others can be protected.

If you already entered a password or approved a prompt, report it immediately. Speed matters: IT can reset the password, revoke sessions, check for mailbox rules, and look for related messages before the attacker uses the access.

  • Report even if you are unsure—false alarms are useful data.
  • Never share MFA codes or approve unexpected prompts.
  • Verify payment changes with a known contact before acting.

Practical action plan

Steps your business can take

01

Verify unusual requests using a known phone number or separate communication channel.

02

Use MFA, email filtering, domain authentication, and safe-link protections.

03

Train employees to inspect sender details, links, tone, and unexpected attachments.

04

Make reporting easy and respond quickly when someone clicks or enters credentials.

Frequently asked questions

Common questions, answered.

What does a phishing email look like today?

Often polished and specific, such as a shared document, invoice, or MFA notice that leads to a fake sign-in page. Spelling mistakes are no longer a reliable sign.

What should I do if I clicked a phishing link?

Report it immediately. If you entered a password or approved a prompt, IT can reset the account, revoke sessions, and check for malicious rules.

Is phishing only an email problem?

No. Attackers also use text messages, phone calls, collaboration apps, and QR codes.
