Since so many people around the world depend on email,
it has become one of the primary attack methods used by
cyber criminals. In this newsletter, we explain phishing, a common email attack method, and the steps you can take to use
email safely.
Phishing
Phishing refers to an attack that uses email or a messaging service (like those on social media sites) that tricks or fools
you into taking an action, such as clicking on a link or opening an attachment. By falling victim to such an attack, you risk
having your highly sensitive information stolen and/or your computer infected. Attackers work hard to make their phishing
emails convincing. For example, they will make their email look like it came from someone or something you know, such as
a friend or a trusted company you frequently use. They will even add logos of your bank or forge the email address so the
message appears more legitimate. Then the attackers send these phishing emails to millions of people. They do not know
who will fall victim, all they know is the more emails they send, the greater the chance for success. Phishing is similar to
using a net to catch fish; you do not know what you will catch, but the bigger the net, the more fish you will find. There are
several ways attackers use phishing to get what they want:
Harvesting Information: The attacker’s goal is to harvest your personal information, such as your passwords, credit
card numbers or banking details. To do this, they email you a link that takes you to a website that appears legitimate. This

website then asks you to provide your account information
or personal data. However, the site is fake, and any
information you enter goes directly to the attacker.
Malicious Links: The attacker’s goal is to take control
of your device. To do this, they send you an email with a
link. If you click on the link, it takes you to a website that
launches an attack on your device that, if successful, infects
your system.
Malicious Attachments: The attacker’s goal is the
same, to infect and take control of your device. But instead
of a link, the attacker emails you an infected file, such as

good to be true, it may be a phishing attack.
Scams: Some phishing emails are nothing more than
scams by con artists who have gone digital. They try to fool
you by saying you won the lottery, pretending to be a charity
needing donations or asking for your help to move millions of dollars. If you respond to any of these, they will say they first
need payment for their services or access to your bank account, scamming you out of your money.
Protecting Yourself
In almost all cases, opening and reading an email or message is fine. For a phishing attack to work, the bad guys need to
trick you into doing something. Fortunately, there are clues that a message is an attack. Here are the most common ones:
• The email creates a sense of urgency, demanding “immediate action” before something bad happens, like closing
your account. The attacker wants to rush you into making a mistake without thinking.
• You receive an email with an attachment that you were not expecting or the email entices you to open the attachment.
Examples include an email saying it has an attachment with details of unannounced layoffs, employee salary
information or a letter from the IRS saying you are being prosecuted.
• Instead of using your name, the email uses a generic salutation like “Dear Customer.” Most companies or friends
contacting you know your name.

Phishing
• The email requests highly sensitive information, such as your credit card number or password.
• The email says it comes from an official organization, but has poor grammar or spelling, or uses a personal email
address like @gmail.com, @yahoo.com or @hotmail.com.
• The link looks odd or not official. One tip is to hover your mouse cursor over the link until a pop-up shows you
where that link really takes you. If the link in the email doesn’t match the pop-up destination, don’t click it. On mobile
devices, holding down your finger on a link gets the same pop-up. An even safer step is to copy and then paste the
URL from the email into your browser or type the correct link.
• You receive a message from someone you know, but the tone or wording just does not sound like him or her. If you
are suspicious, call the sender to verify they sent it. It is easy for a cyber attacker to create an email that appears
to be from a friend or coworker.
If you believe an email or message is a phishing attack, simply delete it. Ultimately, common sense is your best defense.
