This is a typical mail a phishing campaign would send out, and we have already said to people "never believe this kind of messages. They are all fake.
Now, if a genuine company sends out mails with a genuine gift-cards (what the article on techcrunch seems to indicate) … this is NOT helpfull at all!!!
And that comming from a cybersecurity company (rolling-eyes)
Buy a $10 Xbox gift card and send us the code so that we can activate it. Then you get back to the shop and get $20 in cash - $10 for returning the card and $10 from us. We’ll pay the tax, too.
