Never Give Someone Your Password

If an individual calls and says that they are from Microsoft, your bank, Facebook, etc., and then they ask you for your username and/or password, never give it to them! It is always a scam. Check out this story below:

There are a few simple steps to avoid phishing attacks / social engineering such as above:

1) If you didn't call the institute to request help, don't respond to someone saying that they noticed a problem and that they are there to help you.
2) Never give out a Username or Password. Ever. There is no exception to this rule. If the IT guy asks for it, say no. They DO NOT need it.
3) Never give out your bank account number, credit card number, or any personal information such as birth date and SSN unless you specifically called the institution on their listed number. This number is on the back of the card, your bank statement, or another bill. Still, never give out the full bank account number or CC number for verification purposes. The last four digits should always do.
4) If you ever feel uneasy, ask to speak with a manager. Get the managers name and then tell them you will call back in 10 minutes. Hang up and call customer support. Give them the individuals name and make sure that they really work their. If they give you a number for a direct line, don't take it.
5) If you ever have a doubt, call your local branch (if bank or other store) and ask them to help you out. If it is a company like Dell, Microsoft, HP, etc. Call their Customer call center.
6) Use common sense and your gut feeling. If something feels off, it most likely is.
