How to: avoid being phished

Never respond to emails that request personal fi nancial information:

You should be suspicious of any email that asks for your password or account details or includes links for that purpose. Banks or e-commerce companies do not usually send such emails.

Look for signs that an email is “phishy”:

Phishing mails usually use a generic greeting, such as “Dear valued customer”, because the email is spam and the phisher does not have your name. They may also make alarming claims, e.g. that your account details have been stolen or lost. The email often includes misspellings or substitute characters, e.g. “1nformati0n”, in an attempt to bypass anti-spam software.

Visit banks’ websites by typing the address into the address bar:

Don’t follow links embedded in an unsolicited email. Phishers often use these to direct you to a bogus site. Instead, you should type the full address into the address bar in your browser.

Keep a regular check on your accounts:

Regularly log into your online accounts and check your statements. If you see any suspicious transactions, report them to your bank or credit card provider.

Check the website you are visiting is secure:

Check the web address in the address bar. If the website you are visiting is on a secure server, it should start with “https://” (“s” for secure) rather than the usual “http://”. Also look for a lock icon on the browser’s status bar. This tells you that the website is using encryption, but doesn’t necessarily mean that the website is legitimate.

Be cautious with emails and personal data:

Look at your bank’s advice on carrying out safe transactions. Don’t let anyone know your PINs or passwords, do not write them down, and do not use the same password for all your online accounts. Don’t open or reply to spam emails as this lets the sender know that your address is valid and can be used for future scams.

Keep your computer secure:

Anti-spam software will prevent many phishing emails from reaching you. A fi rewall also helps to keep your personal information secure and block unauthorized communications. You should also run anti-virus software to detect and disable malicious programs, such as spyware or backdoor Trojans, which may be included in phishing emails. Keep your internet browser up to date with the latest security patches.

Always report suspicious activity:

If you receive an email you suspect isn’t genuine, forward it to the spoofed organization. (Many companies have a dedicated email address for reporting such abuse.)
