Why taking Facebook quizzes is a really bad idea

Which Dr. Seuss character are you? Who will be your Valentine's Day date?Only a true genius will score 100 per cent on this quiz.

Popular social media quizzes, like the ones that pop up in Facebook feeds,may look harmless and funbut taking them can leave you vulnerable to identity theft or fraud, according toCBC Information Morningtech columnist Nur Zincir-Heywood.

The Better Business Bureau, media literacy groups andpolice departments warn that hackers and scammersare behind many of thesesocial media quizzes, so they cancollect, use and profit from the personalinformation you share.

"Never do these," saidZincir-Heywood, a cybersecurity expert who teaches in the computer science department at Dalhousie University.

She said social media quizzes can ask the same questions your financial organizations use for security purposes to verify youridentity when you need to change your password or access your account without a password. Some examples includethe name of your hometown orthe name of your first pet.

The different questions may not all be asked on the same quiz, she said. But multiple quizzes can elicitenough information that a cybercriminal might be able toaccess a bank or credit card account.

Zincir-Heywood said this can leave you vulnerable.

"Maybe they are watching [your] social media in general, they know your location, they know other things about you," Zincir-Heywood said.

"All of these then put together is a way to collect your information and, in your name, maybe open another account or use your account to buy their own things. It can go really bad."

Zincir-Heywood offers the following tech tips to protect yourself from their more nefarious side ofsocial media quizzes:

• Be careful. Free quizzes offered on social media actually aren't free you're paying with your personal data that big data companies collect for targeted advertising, orcybercriminals collect to sell on the dark web.
• If you can't resist filling out these quizzes, provide fake information, especially to questions similar to security questions used by your financial institutions. For example, if you are asked, 'What is your favourite pet,' make up an answer.
• Once you take these quizzes, you can't take back the information you provide. So keep a closeeye on your online transactions for any unusual banking or credit card activity, for example a transaction you did not authorize or an account you did not create.
