Detect & Protect

Watch out for these common email phishing scams:

  1. Forceful / faked urgency to get you to respond before you think.
  2. Offer a prize or reward to tempt you to click on a link.
  3. Use “masked” links that look like a trusted website address but take you somewhere else when you click on it.
  4. Ask you to provide your password or other confidential data for security purposes.
  5. Website addresses that are similar to, but not the same as the real thing; make sure to inspect the URL if you’re not sure. For example google.com could look like g00gle.com.
  6. Poor spelling and/or unusual grammar.

Similarly, your password is your first line of defense against hackers. Make sure it gets the attention it deserves. Change your password frequently and set it to at least 12 characters long, with a combination of numbers, letters, and special characters. We’ve discussed about his here.
