Question 5. What’s the passage mainly about? ----- Passage 1 ----- (Para. 1)To an identity thief, your personal information can provide instant access to your financial accounts, your credit record, and other assets. If you think no one would be interested in your personal information, think again. Anyone can be a victim of identity theft. In fact, according to the Federal Trade Commission, millions of people become victims every year. How do criminals get your personal information online? One way is by lying about who they are, to convince you to share your account numbers, passwords, and other information so they can get your money or buy things in your name. The scam is called “phishing”: criminals send email, text, or messages that appear to come from your bank, a government agency, an online seller or another organization with which you do business. The message asks you to click to a website or call a phone number to update your account information or claim a prize or benefit. It might suggest something bad will happen if you don’t respond quickly with your personal information. In reality, legitimate businesses should never use email, pop-ups, or text messages to ask for your personal information. (Para. 2)To avoid phishing: (Para. 3)Don’t reply to an email, text, or message that asks for personal or financial information, and don’t click on links in the message. If you want to go to a bank or firm’s website, type the web address into your browser yourself. (Para. 4)Don’t respond if you get a message, by email, text or phone, that asks you to call a phone number to update your account or give your personal information to access a refund. (Para. 5)Some identity thieves have stolen personal information from many people at once, by hacking into large databases managed by businesses or government agencies. While you can't enjoy the benefits of the Internet without sharing some personal information, you can take steps to share only with organizations you know and trust. Don’t give out your personal information unless you find out how it's going to be used and how it will be protected. ----- Question 5. What’s the passage mainly about?
