Phishing: The #1 Way In

Why phishing beats every exploit

Phishing is a fraudulent message that impersonates someone you trust to trick you into clicking a link, opening an attachment, handing over a password, or approving a payment. It is consistently the single most common entry point for real breaches — cheaper, faster and more reliable for an attacker than any software vulnerability, because it targets the person instead of the code.

This course is the defender's side of the story: how to recognise, stop and report phishing across every channel. We explain attacker technique only as far as you need to spot it — the goal is detection and response, not running a campaign.

What you will be able to do

• Name the phishing channels: email, smishing (SMS), vishing (voice), quishing (QR codes).
• Read a suspicious URL and find the real domain.
• Interpret SPF, DKIM and DMARC results in an email header.
• Know exactly what to do in the first minutes after a click.
