Phishing is the most common cyber attack in the world. It doesn't break into your computer with clever code — it tricks *you* into handing over the keys. Understanding how phishing works is the single most valuable cyber security skill you can learn.
How Phishing Works
A phishing attack usually starts with a message — an email, SMS, or DM — that pretends to be from someone you trust: your bank, a delivery company, or even your boss. The message creates urgency ("Your account will be locked!") and includes a link. That link leads to a fake login page that looks identical to the real one. You type your password, and the attacker captures it.
The whole attack takes minutes to set up and seconds to succeed.
7 Warning Signs of a Phishing Message
- Urgency and threats — “Act now or lose access.” Legitimate companies rarely pressure you like this.
- Suspicious sender address — Check the full email, not just the display name. `support@paypa1.com` is not PayPal.
- Generic greetings — “Dear customer” instead of your name.
- Unexpected attachments or links — Especially `.zip`, `.html`, or shortened URLs.
- Too-good-to-be-true offers — You didn't win a lottery you never entered.
- Requests for sensitive info — Banks never ask for passwords by email.
- Poor grammar and odd phrasing — A classic, though AI is making this harder to spot.
Common Types of Phishing
- Email phishing — Mass-sent fake emails impersonating trusted brands.
- Spear phishing — Targeted attacks customized with your name, job, or company.
- Smishing — Phishing via SMS text messages (“Your package is held — click here”).
- Vishing — Voice phishing: scam phone calls pretending to be tech support or officials.
- Whaling — Spear phishing aimed at executives and high-value targets.
How to Protect Yourself
- Never click links in unexpected messages. Go to the official site by typing the address yourself.
- Enable two-factor authentication (2FA) everywhere — even a stolen password becomes useless.
- Hover before you click to preview the real URL.
- Verify through another channel. Got a strange request from your “boss”? Call them.
- Use a password manager. It won't autofill credentials on fake domains — a silent alarm.
- Keep software updated. Browsers and email apps constantly improve phishing filters.
What To Do If You Clicked
Don't panic. Immediately change the password on the real site, enable 2FA, check your account for unauthorized activity, and if you entered payment details, contact your bank. Report the phishing email to your provider.
Phishing succeeds because of human psychology, not technical wizardry. Slow down, verify, and you'll stop the vast majority of attacks before they start.
