Taking Facebook Quizzes Could Put You at Risk for Identity Theft

From phishing schemes to a thief pilfering your passport, there are plenty of ways to fall victim to identity theft. And now, participating in Facebook quizzes is one of them. As ABC News reports, the seemingly harmless surveys that populate your feed could wind up providing unscrupulous hackers with the answers to your online security questions.

Popular Facebook quizzes often ask users to answer a series of sharable personal questions, ranging from the name of their pet to their birth city. Some people see them as a fun way to bond with friends, or a way to make new ones. But as one local police department in Massachusetts recently noted on Facebook, many of these queries are similar—if not identical—to security questions used by banks and other institutions.

"Please be aware of some of the posts you comment on," the Sutton Police Department in Massachusetts wrote in a cautionary message. "The posts that ask what was your first grade teacher, who was your childhood best friend, your first car, the place you [were] born, your favorite place, your first pet, where did you go on your first flight … Those are the same questions asked when setting up accounts as security questions. You are giving out the answers to your security questions without realizing it."

Hackers can use these questions to build a profile and hack into your accounts or open lines of credit, the department said. They could also trick you into clicking on malicious links.

Experts say it's OK to take part in a Facebook quiz, but you should never reveal certain personal facts. Take quizzes only from respected websites, and always carefully vet ones that ask for your email address to access the poll or quiz. And while you're at it, consider steering clear of viral memes, like this one from 2017, which asked Facebook users to name memorable concerts (yet another common security question).

Samsung Is Making a Phone You Can Fold in Half

The iPhone vs. Galaxy war just intensified. Samsung is pulling out all the stops and developing a foldable phone dubbed Galaxy X, which it plans to release next year, according to The Wall Street Journal.

It would seem the rumors surrounding a mythical phone that can fold over like a wallet are true. The phone, which has been given the in-house code name “Winner,” will have a 7-inch screen and be a little smaller than a tablet but thicker than most other smartphones.

Details are scant and subject to change at this point, but the phone is expected to have a smaller screen on the front that will remain visible when the device is folded. Business Insider published Samsung patents back in May showing a phone that can be folded into thirds, but the business news site noted that patents often change, and some are scrapped altogether.

The Galaxy Note 9 is also likely to be unveiled soon, as is a $300 Samsung speaker that's set to rival the Apple HomePod.

The Galaxy X will certainly be a nifty new invention, but it won’t come cheap. The Wall Street Journal reports the phone will set you back about $1500, which is around $540 more than Samsung’s current most expensive offering, the Galaxy Note 8.

Why a Readily Available Used Paperback Is Selling for Thousands of Dollars on Amazon

At first glance, getting ahold of a copy of One Snowy Knight, a historical romance novel by Deborah MacGillivray, isn't hard at all. You can get the book, which originally came out in 2009, for a few bucks on Amazon. And yet according to one seller, a used copy of the book is worth more than $2600. Why? As The New York Times reports, this price disparity has more to do with the marketing techniques of Amazon's third-party sellers than it does the market value of the book.

As of June 5, a copy of One Snowy Knight was listed by a third-party seller on Amazon for $2630.52. By the time the Times wrote about it on July 15, the price had jumped to $2800. That listing has since disappeared, but a seller called Supersonic Truck still has used copy available for $1558.33 (plus shipping!). And it's not even a rare book—it was reprinted in July.

The Times found similar listings for secondhand books that cost hundreds if not thousands of dollars more than their market price. Those retailers might not even have the book on hand—but if someone is crazy enough to pay $1500 for a mass-market paperback that sells for only a few dollars elsewhere, that retailer can make a killing by simply snapping it up from somewhere else and passing it on to the chump who placed an order with them.

Not all the prices for used books on Amazon are so exorbitant, but many still defy conventional economic wisdom, offering used copies of books that are cheaper to buy new. You can get a new copy of the latest edition of One Snowy Knight for $16.99 from Amazon with Prime shipping, but there are third-party sellers asking $24 to $28 for used copies. If you're not careful, how much you pay can just depend on which listing you click first, thinking that there's not much difference in the price of used books. In the case of One Snowy Knight, there are different listings for different editions of the book, so you might not realize that there's a cheaper version available elsewhere on the site.

Even looking at reviews might not help you find the best listing for your money. People tend to buy products with the most reviews, rather than the best reviews, according to recent research, but the site is notorious for retailers gaming the system with fraudulent reviews to attract more buyers and make their way up the Amazon rankings. (There are now several services that will help you suss out whether the reviews on a product you're looking at are legitimate.)

For more on how Amazon's marketplace works—and why its listings can sometimes be misleading—we recommend listening to this episode of the podcast Reply All, which has a fascinating dive into the site's third-party seller system.
