Cyber Security: Spotting a Phishing Email

Example phishing email. Logo of Trusted bank – looks real. Text claims to be from bank, claiming there is fraudulent activity on your account and asking the recipient to confirm personal details. Real banks will never ask this via email.

Spotting a phishing email

Although a phishing attack may appear plausible at first glance, there are some tell-tale signs that should make you very cautious about clicking on any links or giving any personal information to the supposed sender.
Read through the points below to find out what to look out for.
  • Spelling mistakes Most English-language phishing expeditions are sent from countries where English is not the primary language. Attackers often give themselves away by imprecise use of English, even with quite common phrases, and including spelling errors. So read the message carefully.
  • Who is it to? Many, but not all phishing attacks do not use your name in the introduction – preferring ‘Dear valued customer,’ or ‘Dear user,’. This is because they cannot personalise the emails sufficiently. Your bank or online store can do this and should address you as ‘Dear Bob,’ or ‘Dear Mrs Jones,’ (or whatever your name is).
  • Poor quality images Sometimes, the images used in the emails are fuzzy, or your information may appear as an image rather than type. These images have been copied from screens and would not be used by original companies. It is easy to obtain images every bit as good as the originals though, so a high quality image should not persuade you the message is genuine.
  • Content of the email In almost all countries, banks and other financial bodies will not email you to tell you about problems with your account. They recognise that email is fundamentally insecure and that personal information should not be sent by email. So, even the method of communication will give you a clue about whether it’s genuine. The email may give a false sense of urgency, claiming that your account is at risk if you do not act quickly. This is not the case.
  • Links The text of a web link is not the same as the destination of the link itself – the link might say it is taking you tohttp://www.trustedbank.com, but in fact it can take you anywhere on the web – including to a phisher’s computer impersonating that of a reputable company. You can easily spot a fake link by hovering your mouse pointer over the link – but do not click the button. The actual destination of the link will appear at the bottom of the window or in a small floating window next to the link. In a phishing email, the link will probably be to an address you aren’t familiar with.

The example message below claims to come from a fictional site called ePay and is about unauthorised activity on the account. The link says it goes to ePay’s site, but the address is slightly different and is unlikely to be owned by ePay.
Example screen shot of a web page displaying a phishing email. Tab states: MyEmail – Inbox. Web address line states: www.myemail.com/inbox. Navigation across the top of the example web page: Inbox, Sent, Junk Mail, Contacts, Recycle Bin, Settings. Content of the message: logo of ePay, Dear ePay customer, We recently reviewed your account, and we suspect an unauthorised transaction on your account. Protecting your account is our primary concern. As a preventive measure we have temporary limited your access to sensitive information. 
                  To ensure that your account is not compromised, simply hit the link below and confirm your identity as a member of ePay. 
                  http://www.epay.com/confirm
                  *Please do not reply to this message, Mail sent to this address cannot be answered.

                  A mouse arrow is hovering over the web site address and at the bottom of the message there is the address to which this link points. It is: www.epay-secure-check.com/en/login.php

So the rules are to be suspicious and to look at the details of the message, the language, the quality of the images and where the links actually take you. Banks and shops will always prefer you to call them and check rather than risking your security.
