Facebook - How Free Gift Scams work
Excellent advice by PC Magazine as scam attacks work through malicious applications on Facebook that appear to come from a trusted friend or contact. Avoid clicking the LIKE button or visiting a URL offered if it seems to good to be true.
QUOTE: "Get free stuff!" is a common lure scammers use on Facebook. It doesn't matter if the pitch is for a free airplane ticket, a free iPad, or just a voucher for a free coffee. Everyone likes getting something for free. While the bulk of Hunt's analysis focused on a supposed $400 voucher promotion from Australian retailer Woolworths, there are similar scams for other retailers, including Starbucks, Costco, and Harvey Norman, he said. "The scam relies of the power of social media leverage by making the victim the advocate for the scam. It’s their wall that's telling all their friends how awesome the scammer's page is," Hunt wrote.
It all begins with a friend. Or more precisely, a post from a Facebook friend in the Newsfeed advertising a voucher or a free gift from a company. Users who click on the link first land on the promotion page, which displays a share widget, user comments, and a Like button. After the user completes all three steps (and ensures friends will now see the post in their Newsfeeds), the user is redirected several times before landing on the final scam page. It may be a survey site, a form asking users to fill out information to win a prize, or some other malicious site. There will be no sign of that initial free gift, though.
