Phishing attacks explained: a simple guide for non-technical leaders — Phishing & Email Security illustration

Phishing is the most common way UK SMEs get breached. Not zero-days. Not state actors. A convincing email or message that gets one person to click, type a password, or approve an MFA prompt.

What phishing actually is

A phishing attack is any attempt to trick someone into doing something harmful — usually by impersonating a trusted brand, colleague or supplier. The goal is almost always one of three things:

  • Steal credentials (usernames, passwords, MFA codes).
  • Trick a payment (change bank details, approve an invoice).
  • Install malware (a document, link or fake software update).

Why modern phishing slips past filters

2026's phishing rarely looks like the dodgy emails of a decade ago. Attackers now:

  • Use legitimate services (Microsoft, DocuSign, Dropbox) to host the lure.
  • Compromise a real supplier's mailbox and reply inside an existing thread.
  • Generate clean, on-brand copy with AI — no spelling mistakes, correct tone.
  • Send MFA-prompt-bombing or push-notification fatigue attacks.

The signals to train your team on

  1. Unexpected urgency — 'pay today', 'approve now', 'before close of business'.
  2. Any request to change bank details, even from a known supplier.
  3. A login page asking for credentials after clicking an email link.
  4. MFA prompts you didn't trigger.
  5. Attachments or links you weren't expecting, even from real contacts.

What actually reduces phishing risk

Awareness alone isn't enough. The combination that works:

  • MFA on every account — ideally phishing-resistant (passkeys, FIDO2).
  • Email authentication (SPF, DKIM, DMARC at p=reject).
  • Modern email security that inspects URLs at click time, not just send time.
  • Short, regular training plus realistic phishing simulations.
  • A clear, blame-free reporting button so staff flag suspicious mail in seconds.
