What phishing is, quickly

Phishing is when someone pretends to be a trusted company or person (bank, postal service, tax authority, supplier) by email to trick you into clicking a malicious link or providing sensitive data, like a password or card number.

The most common warning signs

How to check before clicking

Never click directly on the link in a suspicious email. Instead, open the company's official site by typing the address manually in your browser, or call a phone number you already know (not the one in the email) to confirm.

I already clicked a suspicious link, now what?

Don't enter any information on the page that opened. If you've already typed a password, change it immediately on the official site (not through the email link) and enable two-factor authentication, if you haven't already. Also run an antivirus scan on your computer.

Frequently asked questions

Do banks and serious companies ask for passwords by email?

No. No serious institution asks for a password, a full verification code, or card details by email. Any message asking for this should be treated as suspicious by default.

How do I recognize a fake email domain?

Carefully compare the sender's domain (the part after the @) with the company's official site — scammers often use subtle variations, like swapping a letter or adding extra words to the domain.
