How To Avoid Phishing and Spear Phishing

Phishing is when someone sends you an email that looks like it came from a bank or service you trust. They try to get you to open an attachment that compromises your device or to click on a web link and to sign in on a malicious website.

Spear phishing is the same as phishing, except the email you receive is especially crafted just for you. The attacker has researched you well and knows who your friends, family and associates are. They may know who you work for and what you are working on. The phishing email received in a spear phishing campaign looks much more authentic, appears to come from someone you know and may refer to something you are working on. Spear phishing attacks have a much higher success rate.

Follow these two simple rules to avoid a phishing or spear phishing campaign:

  1. Never open an attachment unless you are 100% certain that someone you trust sent it to you. If you have any doubt at all, pick up the phone and call the person.
  2. Never click on a website link unless you are 100% certain that the person or organization that sent it to you is someone you trust. When you do open the link, check your browser location bar at the top for the following:
    • The location should start with https://
    • The part after https:// should be the domain name of an organization you trust. For example, it should say paypal.com and not paypal.com.badsite.com. Everything from the first forward slash to the final forward slash in the location should be a name that you trust.
    • The https:// part should be green if you are using Chrome and it should also say “Secure” to the left.

If you receive an email that looks suspicious in any way, just delete it. Then pick up the phone and call the person who sent it to you. They may not know their email account has been hacked.
