Over the past few months, Americans have been receiving emails promising them a free Yeti backpack cooler from Dick's Sporting Goods — a $325 value. These emails have gotten a lot of attention because they are sometimes able to evade sophisticated spam filters, like those built into Google 's Gmail, but they are spam emails. The spam campaign is an example of how scammers are getting increasingly sophisticated at targeting consumers to give up their private information, said Or Katz, principal security researcher at Akamai , which recently published a look into how the recent spam campaign works. A Google representative called the phishing campaign "widespread" and "particularly aggressive." The spam campaign hitting user inboxes is another reminder that online fraud is a major industry, driven by money, that continues to evolve.
